  The committee met, pursuant to notice, at 10:05 a.m., in room 2318, Rayburn House Office Building, Hon. J. Edward Roush (chairman of the symposium) presiding.   Mr. Roush. The committee will be in order.   Today the House Committee on Science and Astronautics conducts a very special session, a symposium on the subject of unidentified flying objects; the name of which is a reminder to us of our ignorance on this subject and a challenge to acquire more knowledge thereof. We approach the question of unidentified flying objects as purely a scientific problem, one of unanswered questions. Certainly the rigid and exacting discipline of science should be marshaled to explore the nature of phenomena which reliable citizens continue to report. A significant part of the problem has been that the sightings reported have not been accompanied by so-called hardware or materials that could be investigated and analyzed. So we are left with hypotheses about the nature of UFO’s. These hypotheses range from the conclusion that they are purely psychological phenomena, that is, some kind of hallucinatory phenomena; to that of some kind of natural physical phenomena; to that of advanced technological machinery manned by some kind of intelligence, that is, the extraterrestrial hypotheses.   With the range in mind, then, we have invited six outstanding scientists to address us today, men who deal with the physical, the psychological, the sociological, and the technological data relevant to the issues involved. We welcome them and look forward to their remarks. Additionally we have requested several other scientists to make their presentations in the form of papers to be added to these when published by the committee.   We take no stand on these matters. Indeed, we are here today to listen to their assessment of the nature of the problem; to any tentative conclusions or suggestions they might offer, so that our judgments and our actions might be based on reliable and expert information. We are here to listen and to learn.   Events of the last half century certainly verify the American philosopher, John Dewey’s conclusion that “Every great advance in science has issued from a new audacity of imagination.” With an open and inquiring attitude, then, we now turn to our speakers for the day.

[[1]]

    They will include:     Dr. J. Allen Hynek, head of the Department of Astronomy, Northwestern University;   Dr. James E. McDonald, senior physicist, the Institute of Atmospheric Physics, the University of Arizona;   Dr. Carl Sagan, Department of Astronomy and Center for Radiophysics and Space Research, Cornell University;   Dr. Robert L. Hall, head of the Department of Sociology, University of Illinois at Chicago;   Dr. James A. Harder, associate professor of civil engineering, University of California at Berkeley, and;   Dr. Robert M. L. Baker, Jr., Computer Sciences Corp. and Department of Engineering, UCLA. Gentlemen, we welcome your presentations. We ask you to speak first, Dr. Hynek, followed by Dr. McDonald, and then Dr. Sagan. This afternoon Dr. Hall will commence our session, followed by Dr. Harder and then Dr. Baker. The subject matter of the presentations determines the order in which you speak. We hope at the end of the day to allow the six of you to discuss the material presented among yourselves and with the committee in a kind of roundtable discussion.   Mr. Chairman — the chairman of our full committee, Mr. George Miller.   Chairman Miller. I want to join in welcoming you here. I want to point out that your presence here is not a challenge to the work that is being done by the Air Force, a particular agency that has to deal with this subject.   Unfortunately there are those who are highly critical of the Air Force, saying that the Air Force has not approached this problem properly. I want you to know that we are in no way trying to go into the field that is theirs by law, and thus we are not critical of what the Air Force is doing.   We should look at the problem from every angle, and we are here in that respect. I just want to point out we are not here to criticize the actions of the Air Force.   Thank you.   Mr. Roush. I think it is only appropriate that Dr. Hynek be introduced by our colleague, Mr. Rumsfeld.   Mr. Rumsfeld.   Mr. Rumsfeld. Thank you, Mr. Chairman. It is a pleasure to welcome all the members of this distinguished panel, and particularly to welcome Dr. Allen Hynek, who is a son of Illinois, and presently serves in the Department of Astronomy and Director of the Lindheimer Astronomical Research Center. Dr. Hynek is a member of a number of scientific societies, and has served in the Government service as well as in the academic community. As his Congressman I am delighted he has been invited to appear on this panel, and we certainly look forward to his comments.   Thank you, Mr. Chairman.   Mr. Roush. Dr. Hynek, the floor is yours.     STATEMENT BY DR. J. ALLEN HYNEK 1. Biography 2. Start of Oral Statement 3. Article Read into the Record 4. Continuation of Oral Statement 5.

STATEMENT OF DR. J. ALLEN HYNEK, HEAD, DEPARTMENT OF ASTRONOMY, NORTHWESTERN UNIVERSITY, EVANSTON, ILL.   Dr. Hynek. Thank you.   My name is J. Allen Hynek. I am professor of astronomy at Northwestern University, Evanston, Ill., where I serve as chairman of the department of astronomy and director of the Lindheimer Astronomical Research Center. I have also served for many years, and still do, as scientific consultant to the U..S. Air Force on Unidentified Flying Objects, or UFO’s. Today, however, I am speaking as a private citizen and scientist and not as a representative of the Air Force.   We are here today, I gather, to examine whether the UFO phenomenon is worthy of serious scientific attention. I hope my comments may contribute to your understanding of the problem and help lead to its eventual solution.   The UFO problem has been with us now for many years. It would be difficult to find another subject which has claimed as much attention in the world press, in the conversation of people of all walks of life, and which has captured the imagination of so many, over so long a period of time. The word UFO, or flying saucer, can be found in the languages and dictionaries of all civilized peoples, and if one were to collect all the words that have been printed in newspapers, magazines, and books in the past two decades, it would be a staggering assemblage. The bibliography of the subject recently compiled at the Library of Congress is a most impressive document, and illustrates that the UFO became a problem for the librarian even before it did for the scientist.   As we all know, the scientific world is a world of exact calculations, of quantitative data, of controlled laboratory experiments, and of seemingly well-understood laws and principles. The UFO phenomenon does not seem to fit into that world; it seems to flaunt itself before our present-day science.   The subject of UFO’s has engendered an inordinate emotional reaction in certain quarters and has far more often called forth heated controversy rather than calm consideration. Most scientists have preferred to remain aloof from the fray entirely, thereby running the risk of “being down on what they were not up on,” as the old adage goes.   It is unlikely that I would have become involved in the study of the UFO phenomenon had I not been officially asked to do so. I probably would have — and in fact did for a time — regarded the whole

[[3]]

  subject as rank nonsense, the product of silly seasons, and a peculiarly American craze that would run its course as all popular crazes do.   I was asked by the Air Force 20 years ago to assist them, as an astronomer, in weeding out those reports arising from misidentification of planets, stars, meteors, and other celestial objects and events. In the course of doing my “homework” I found that some 30 percent of the then current cases very probably had astronomical causes, but my curiosity was aroused by some of the patently nonastronomical reports.   These were ostensibly being explained by the consultant psychologist, but I frequently had the same feeling about the explanations offered for some of these cases that I have had when I have seen a magician saw a woman in half. How he did it was beyond my own field of competence, but I did not question his competence. Yes, I was quite sure that he did not actually saw the woman in half!   My curiosity thus once aroused led me to look into reports other than those of a purely astronomical nature, and in the course of years I have continued to do so. I have pondered over the continuing flow of strange reports from this and a great many other countries, for it is a gross mistake to think that the United States has any exclusive claim to the UFO phenomenon.   Those reports which interested me the most — and still do — were those which, apparently written in all seriousness by articulate individuals, nonetheless seemed so preposterous as to invite derisive dismissal by any scientist casually introduced to the subject. Such baffling reports, however, represent a relatively small subset of reports. I did not — and still do not — concern myself with reports which arise from obvious misidentifications by witnesses who are not aware of the many things in the sky today which have a simple, natural explanation. These have little scientific value, except perhaps to a sociologist or an ophthalmologist; it matters not whether 100 or 100,000 people fail to identify an artificial satellite or a high-altitude balloon.   The UFO reports which in my opinion have potential scientific value are those — and this may serve us as a working definition of UFO’s — are those reports of aerial phenomena which continue to defy explanation in conventional scientific terms. Many scientists, not familiar with the really challenging UFO data, will not accept the necessity for a high order of scientific inquiry and effort to establish the validity of the data — and therefore such detailed, conscientious, and systematic inquiry has yet to be undertaken.   We cannot expect the world of science to take seriously the fare offered at airport newsstands and paperback shelves.   I have been asked by some why, as consultant to the Air Force for so many years, I did not alert the scientific world to the possible seriousness of the UFO problem years ago. The answer is simple; a scientist must try to be sure of his facts. He must not cry “wolf” unless he is reasonably sure there is a wolf.   I was painfully aware, and still am, of the amorphous nature of the UFO data, of the anecdotal nature of UFO reports, of the lack of followup and serious inquiry into reports (which would have required a large scientific staff and adequate funding), of the lack of hardware, of the lack of unimpeachable photographic evidence, and

[[4]]

of the almost total lack of quantitative data — of all those things which are part and parcel of the working environment of the scientist.   I was aware that in order to interest scientists, hard-core data were needed, and, while the store of unquestionably puzzling reports from competent witnesses continued to grow the wherewithal to obtain such hard-core data which would, once and for all, clinch the matter, was not forthcoming. Thus my scientific reticence was based on a carefully weighed decision.   In attempting analysis of the UFO problem today, I pay particular attention to reports containing large amounts of information which are made by several witnesses, if possible, who as far as I can ascertain, have unimpeachable reputations and are competent. For example, I might cite a detailed report I received from the associate director of one of the Nation’s most important scientific laboratories, and his family.   Reports such as these are obviously in a different category from reports which, say, identify Venus as a hovering spaceship, and thus add to the frustrating confusion.   On the other hand, when one or more obviously reliable persons reports — as has happened many times — that a brightly illuminated object hovered a few hundred feet above their automobile, and that during the incident their car motor stopped, the headlights dimmed or went out, and the radio stopped playing, only to have these functions return to normal after the disappearance of the UFO, it is clearly another matter.   By what right can we summarily ignore their testimony and imply that they are deluded or just plain liars? Would we so treat these same people if they were testifying in court, under oath, on more mundane matters?   Or, if it is reported, as it has been in many instances over the world by reputable and competent persons, that while they were sitting quietly at home they heard the barnyard animals behaving in a greatly disturbed and atypical manner and when, upon investigating, found not only the animals in a state of panic but reported a noiseless — or sometimes humming — brightly illuminated object hovering nearby, beaming a bright red light down onto the surroundings, then clearly we should pay attention. Something very important may be going on.   Now, when in any recognized field of science an outstanding event takes place, or a new phenomenon is discovered, an account of it is quickly presented at a scientific meeting or is published in a respected appropriate journal. But this is certainly not the case with unusual UFO reports made by competent witnesses.   There appears to be a scientific taboo on even the passive tabulation of UFO reports. Clearly no serious work can be undertaken until such taboos are removed. There should be a respectable mechanism for the publication, for instance, of a paper on reported occurrences of electromagnetic phenomena in UFO encounters.   It would be foolhardy to attempt to present such a paper on UFO’s to the American Physical Society or to the American Astronomical Society. The paper would be laughed down, if all that could be presented as scientific data were the anecdotal, incomplete, and nonquantitative reports available. Consequently reports of unexplainable UFO cases are’ likely to be found, if at all, in pulp magazines and paperbacks,

[[5]]

  of which the sole purpose of many seems to be, apart from making a fast buck for the authors, to titillate the fancy of the credulous.   Indeed, in such newsstand publications three or four UFO reports are frequently sensationalized on one page with gross disregard for accuracy and documentation; the result is that a scientist if he reads them at all is very likely to suffer mental nausea and to relegate the whole subject to the trash heap.   This is the first problem a scientist encounters when he takes a look at the UFO phenomenon. His publicly available source material is almost certain to consist of sensational, undocumented accounts of what may have been an actual event. Such accounts are much akin, perhaps, to the account we might expect from an aborigine encountering a helicopter for the first time, or seeing a total eclipse of the sun. There is nowhere a serious scientist can turn for what he would consider meaningful, hard-core data as hard core and quantitative as the phenomenon itself permits at present.   Here we come to the crux of the problem of the scientist and the UFO. The ultimate problem is, of course, what are UFO’s; but the immediate and crucial problem is, How do we get data for proper scientific study? The problem has been made immensely more difficult by the supposition held by most scientists, on the basis of the poor data available to them, that there couldn’t possibly be anything substantial to UFO reports in the first place, and hence that there is no point to wasting time or money investigating.   This strange, but under the circumstances understandable attitude, would be akin to saying, for instance, let us not build observatories and telescopes for the study of the stars because it is obvious that those twinkling points of light up there are just illusions in the upper atmosphere and do not represent physical things.   Fortunately, centuries ago there were a few curious men who did not easily accept the notion that stars were illusory lights on a crystalline celestial sphere and judged that the study of the stars might be worthwhile though, to many, a seemingly impractical and nonsensical venture. The pursuit of that seemingly impractical and possibly unrewarding study of astronomy and related sciences, however, has given us the highly technological world we live in and the high standard of living we enjoy — a standard which would have been totally impossible in a peasant society whose eyes were never turned toward the skies.   Can we afford not to look toward the UFO skies; can we afford to overlook a potential breakthrough of great significance? And even apart from that, the public is growing impatient. The public does not want another 20 years of UFO confusion. They want to know whether there really is something to this whole UFO business and I can tell you definitely that they are not satisfied with the answers they have been getting. The public in general maybe unsophisticated in scientific matters, but they have an uncanny way of distinguishing between an honest scientific approach and the method of ridicule and persiflage.   As scientists, we may honestly wish to see whether there is any scientific paydirt in this international UFO phenomenon. But to discover this paydirt we must devote serious study to UFO’s. To make

[[6]]

  serious study possible, however, requires recruiting competent scientists, engineers, and technical people, as well as psychologists and sociologists.   This in turn requires not only funds but a receptive scientific climate. Many scientists have expressed to me privately their interest in the problem and their desire to actively pursue UFO research as soon as the scientific stigma is removed. But as long as the unverified presumption is strongly entrenched that every UFO has a simple, rational everyday explanation, the required climate for a proper and definitive study will never develop.   I recall an encounter I had sometime ago with the then chief scientist at the Pentagon. He asked me just how much longer we were “going to look at this stuff.” I reminded him that we hadn’t really looked at it yet that is, in the sense, say, that the FBI looks at a kidnapping, a bank robbery, or a narcotics ring.   Up to this point I have not discussed another major impediment to the acceptance of the UFO phenomenon as legitimate material for scientific study. I refer to the adoption of the UFO phenomenon by certain segments of the public for their own peculiar uses. From the very start there have been psychically unbalanced individuals and pseudoreligious cultist groups — and they persist in force today — who found in the UFO picture an opportunity to further their own fanciful cosmic and religious beliefs and who find solace and hope in the pious belief that UFO’s carry kindly space brothers whose sole aim is a mission of salvation.   Such people “couldn’t care less” about documentation, scientific study, and careful critical consideration. The conventions and meetings these people hold, and the literature they purvey, can only be the subject of derisive laughter and, I must stress, it is a most serious mistake for anyone to confuse this unfortunate aspect of the total UFO phenomenon with the articulate reports made by people who are unmistakably serious and make their reports out of a sense of civic duty and an abiding desire to know the cause of their experience.   It may not be amiss here to remark in passing that the “true believers” I have just referred to are rarely that ones who make UFO reports. Their beliefs do not need factual support. The reporters of the truly baffling UFO’s, on the other hand, are most frequently disinterested or even skeptical people who are taken by surprise by an experience they cannot understand.   Hopefully the time is not far off when the UFO phenomenon can have an adequate and definitive hearing, and when a scholarly paper on the nature of UFO reports can be presented before scientific bodies without prejudice. Despite the scientific attitude to this subject in the past, I nevertheless decided to present a short paper on UFO’s to a scientific body in 1952, following a scientific hunch that in the UFO phenomenon we were dealing with a subject of great possible importance.   In my paper (JOSA 43, pp. 311-314, 1963), which I should like to have read into the record, I made reference to the many cases in 1952 and earlier which were nonastronomical in nature and did not seem to have a logical, ready explanation.

UNUSUAL AERIAL PHENOMENA

J. A. HYNEK, Ohio State University, Columbus, Ohio

(Received December 22, 1952)

  Over a period of years, diverse aerial sightings of an unusual character have been reported. On the assumption that the majority of these reports, often made in concert, come from reputable persons, and in the absence of any universal hypotheses for the phenomena which stimulated these reports, it becomes a matter of scientific obligation and responsibility to examine the reported phenomena seriously, despite their seemingly fanciful character. Accordingly, several hundred serious reports of “unidentified aerial objects” have been studied in detail in an attempt to get a pattern classification. It appears that those reported phenomena which do not admit of a ready and obvious explanation exhibit fairly well-defined patterns and that these are worthy of further study. One pattern in particular, that of a hovering nocturnal light, does not appear to be readily explainable on an astronomical basis or by mirages, balloons, or by conventional aircraft.   Perhaps the most bizarre phenomenon of our times is the continued popular interest in flying saucers. The term flying saucer, of course, dates back to the treatment by the press of the now famous triggering incident of June 24, 1947, another date which might well be said to live in infamy, when a lone pilot, Mr. Arnold, reported “nine peculiar-looking aircraft” without tails, which flew in a chain-like line and “swerved in and out of the high mountain peaks.” The unfortunate newspaper term, flying saucer, as you well know, captured both the press and the public imagination. One can speculate as to the turn of events, and the amount of newsprint that might have been conserved, had Mr. Arnold decided to stay on the ground that day!   Nevertheless, in the past five years, flying saucer has become a standard term in our language, with about as broad a definition as it has been the lot of any term to carry. We can define a flying saucer as any aerial phenomenon or sighting that remains unexplained to the viewer at least long enough for him to write a report about it. Lest anyone misunderstand what shall be meant by “flying saucers” in this paper, this definition must be emphasized. Each flying saucer, so defined, has associated with it a probable lifetime. It wanders in the field of public inspection like an electron in a field of ions, until “captured” by an explanation which puts an end to its existence as a flying saucer.   Thus flying saucers spawned by the planet Venus have generally a short lifetime. In almost no time an astronomer comes along and makes a positive identification, and another flying saucer is shattered. We can expect a host of Venus-inspired flying saucers when this planet is low in the western sky after sunset. It reaches greatest eastern elongation this year on January 31, 1953, and on March 8 attains its greatest brilliance. We can confidently predict a swarm of flying saucers from Venus!   The lifetime of a balloon-sponsored flying saucer is often longer, but before long someone like Dr. Liddell comes along and shoots it down. And Dr. Menzel has as his flying saucer ammunition a large variety of optical effects, the lethalness of which requires separate field tests.   My concern is with flying saucers of long lifetime — those which have not, as yet, been “captured” or demolished by an explanation. Let us further limit them to those that have been observed by two or more people, at least one of whom is practiced in the making of observations of some kind, that is, to pilots, control tower operators, weather observers, scientific workers, etc. Also, let us limit cases to sightings lasting a minute or more, again for obvious reasons.   The Wright-Patterson Air Force Base, where the responsibility for the Investigation of unidentified aerial objects has rested for the past several years, asked me in 1948 to help identify reports that had an astronomical basis. It was a relatively simple task to go through about 200 reports and pick out probable astronomical causes. Indeed, some of the most weird reports could be dismissed with clear conscience by the statement that no astronomical explanation is possible for this incident, thus leaving these unsolved cases to the psychologists.

[[8]]

  I did wonder of course, as to how they were disposing of the nonastronomical cases. How did they explain the incident in which a pilot, co-pilot, and stewardess followed some rapidly moving dark objects which were silhouetted against the sunset sky and which disappeared presumably because of their superior speed? But my faith in the psychologists was unshaken and when the Air Forces announced that Project Grudge had been dissolved, I assumed that my colleagues had been successful and had even solved the case in which several observers watched an object, hollow in the middle, travel at a constant slow rate, taking 15 minutes to make the journey across the sky from north to south.   After the project dissolved, Wright Field continued to take care of the slow but steady flow of reports as a part of their regular intelligence function. This spring I became curious and requested permission, through official channels, to look through the crop of reports that had accumulated since my official connection with Project Grudge had terminated. As I looked through the welter of fanciful tales, inaccurate reporting, of misobservation of natural objects, I could not help, as an astronomer, recalling another wave of stories of stones that fell from heaven. Because of poor reporting and poor imagery, scientific progress in meteorites had been held back for a good century. What a difference in imagery there is between “a stone falling from the sky” and “the interception by the earth of a particle pursuing an orbit around the sun.” The use of improper and inaccurate description of what actually happened kept meteorites in the category of old wives’ tales and out of the niche that celestial mechanics had made ready for them a century before! In 1801, Thomas Jefferson said that he would sooner believe that two Yankee professors had lied than that stones had fallen from heaven. And the French Academy of Sciences branded stories of meteorite falls as fanciful and absurd and dismissed a bona fide meteorite whose fall had been sworn to — as an ordinary stone that had been struck by lightning. Perhaps the moral of this is: Beware the ready explanation!   Now, it is clear that stories of real flying saucers, visitors from space, and strange aircraft violating the laws of physics are as reprehensible to the scientist of today as stones that fell from heaven were to the scientist of yesteryear. But, of course, stones did not fall from heaven that was poor reporting and a wrong slant on a perfectly natural phenomenon. And we don’t have space ships that disregard physical laws. But, do we have a natural phenomenon?   The steady flow of reports, often made in concert by reliable observers, raises questions of scientific obligation and responsibility. Is there, when the welter of varied reports are shorn of, in the words of Pooh Bah, all “Corroborative detail to lend artistic verisimilitude to an otherwise bald and unconvincing narrative” — any residue that is worthy of scientific attention?   Or, if there isn’t, does not obligation still exist to say so to the public — not in words of open ridicule, but seriously, to keep faith with the trust the public places in science and scientists?   The Air Forces are attempting to give all reports a fair hearing, in view of the above. They are having all reported data reduced to punch cards so that in a month or so it will be possible to compare quickly reports made by people facing west on clear Tuesday afternoons with those made on non-inversion Friday nights by pilots going south. In any event, if significant correlations between various sets of sightings exist, this method should bring them out.   In coming down to cases, to illustrate what constitutes at present the best evidence for unusual aerial phenomena, the examples submitted for examination are presented without an all-embracing explanation for them. These are presented in conformance with the school that believes that good observations and discussion of observations come before theory. It is hoped, however, that out of this discussion there may come a positive approach and, if these sightings do represent heretofore inadequately studied natural phenomena, that these examples will stimulate their serious study; if, on the other hand, no natural phenomena are involved, then an obligation exists to demonstrate explicitly how the following specific reports can be explained in terms of balloons, mirages, or conventional aircraft.   The chosen recent examples represent a definite pattern, and for each of the following there are many other similar examples in the flies.   One of these patterns might be called “Nocturnal Meandering Lights.” Reports falling into this category are characterized by the sighting of a bright star-like light, perhaps of -2 or -3 stellar magnitude which floats along without sound, frequently hovers, reverses its field without appearing to turn, and often abruptly speeds up. The light is most frequently described as a yellow amber or orange,

[[9]]

changing to blue or red occasionally, and changing in brightness markedly. Sometimes the description states that the light went out as if someone had pushed a button; at other times the light is reported only as variable. A very characteristic statement by those making the reports is: “I have never seen anything like this in my whole life.” The desire to identify these sightings as balloons is thwarted by the tactics observed.   As an example of a report of this kind, let us take one that came in from Florida this past July. On one night several airmen independently observed a light approach at a very slow speed, come to a halt nearly overhead, then reverse direction with no apparent turn. On two other nights, three other lights appeared in other sections of the sky, of similar appearance, but maneuvering more rapidly. They were observed for some 10 minutes by 9 airmen, including a control tower operator, an aircraft dispatcher, and two pilots from Wright Field.   In the words of one of the men, “For the next fifteen minutes we watched this light and speculated on what it might be. It was not a sharp light like a bare bulb but more like a light shining through frosted glass. No shape of any kind was discernible. It appeared to blink, but with no regularity whatever.”   Also this past July at an air base in New Mexico, a similar sighting was made. Paraphrasing from sworn statements made by observers, “Our station was notified that an unconventional aircraft had been picked up with both electronic and visual contact. Our station made electronic contact with the object and two of our men and I had gone outside the building and saw it hovering under a cloud layer to the east of us. It appeared as a large light, at an uncertain distance, and was hovering at the time. A minute or so later, it moved rapidly toward the north for a short distance and stopped as suddenly as it had begun to move.”   And from another statement, “Our scope operator at that time reported a strange target about thirty miles east of our station. Two of us went outside and sighted a very bright light traveling at what we estimated to be around 200 miles an hour. The light went out at least two times but did not stay out more than two or three minutes. The light seemed to have a floating effect and made no sound. At one time around seven or eight smaller lights could be seen. The object seemed to drop to about 10 or 12 thousand feet and then climbed to about 25,000 taking a northern course.”   Radar observations as well as visual observations are involved in this problem. Early last month shortly before dawn colored lights were observed in the sky southeast of the radar station. At the same time and the same azimuth, unidentified targets appeared on the scope. Only a very slight temperature inversion was present, 1° at 25,000 feet. No more than two lights appeared at one time. They were observed to be moving in a rather erratic pattern and changing colors occasionally. The last thirty minutes of observation revealed the lights remaining yellow prior to that they were red, green, and blue. They moved in no apparent formation but mostly appeared in one area and disappeared in another, when either the light went out or the objects dived behind clouds. They were starlike objects and appeared to develop long, white vapor trails, when they dived. They were motionless at times and moved rapidly at other times. This corresponded to similar movements observed on the radar scope.   One white light went out as it changed direction and continued as a black silhouette against the dawn sky. Observation was for a period of about an hour and was made by two airmen and a radar operator — all three observers were experienced aircraft control and warning operators. Objects were observed 20 to 40° above horizon. Radar gave distances of 50 to 80 miles. This implies a height of about 40 miles. There was no air traffic on radar within 100 miles.   Quoting from the observer’s statement, “receiving a call concerning a strange light in the sky, I went out and scanned the sky in several directions before I saw a light. My first glimpse was a very bright blue light, but it lasted only about a minute, then it faded into a light green. It moved in a slow orbit.   I was startled at first so I closed my eyes and opened them again. The light was still there. I stared at it a few minutes and now the light seemed more yellow than before.   I did not think anyone would believe me, so I went inside the building and relieved the radar scope operator. I found a target at 123°, 53 miles. After that it appeared as a permanent echo. In about two minutes, it disappeared and almost immediately another pip appeared, at 134°, 73 miles. It also seemed

[[10]]

  like a permanent echo. It stayed on the scope for 1½ minutes. These pips were at no time caused by malfunction of the radar set.   It was daylight when it (the object) seemed to fade both visually outdoors and electronically indoors.”   And another sighting — in Northern Michigan — on July 29 of last year, a pilot chased a brilliant multicolored object close to the horizon, and due north. He flew at 21,000 feet, followed the object for over a half-hour but could not gain on it. Radar operator reported contact with the object for about thirty seconds. And ground control interceptor station reported blips too. In this case, it seems certain that our harried pilot was pursuing Capella! Reference to a star map will show that at his latitude, at the time of his sighting, Capella was at lower culmination, that is, at the lowest point of its swing around the pole just skirting the horizon. I have seen it at that position myself in Canada, and, can vouch for the fact that its blue, yellow, and red twinkling can be spectacular.   Unfortunately, neither Capella nor any other star can explain many other nocturnal meandering lights. But there is no question in my mind, just to make this point exceedingly clear, that there exists a relatively simple, natural explanation for them, perhaps even ordinary aircraft under special test conditions. The chief point here, is to suggest that nothing constructive is accomplished for the public at large — and therefore for science in the long run by mere ridicule and the implication that sightings are the products of “bird-brains” and “intellectual flyweights.” In short, it would appear that the flying saucer situation has always been a problem in science-public-relations, and that fine chance has consistently been missed to demonstrate on a national scale how scientists can go about analyzing a problem. A lot is said about the proper interpretation of science to the public, but the only answer they receive to a question about which they are more widely concerned than perhaps any other in this century, is ridicule. Ridicule is not a part of the scientific method and the public should not be taught that it is.   Let me quote an additional report, to show that the original flying disks, as distinct from wandering lights, are still with us.   On the day that our pilot chased Capella, a radio from Seattle announced that flying saucers were seen heading toward Montana. At an airport in Montana several pilots gathered outside the hangars to wait and watch. A perfect set-up for suggestibility and yet, quoting from one of the many signed statements, “Objects were seen that resembled flat disks reflecting sun’s rays. One of the objects hovered from three to four minutes, while the other three circled around it like satellites. Then the stationary object moved southeast to disappear, while the three satellites moved due west and disappeared at very high speeds!”   And from another observer: “After watching for approximately five minutes I was able to see what appeared to be a disk, white or metal in color approaching from the west. As it moved directly overhead it turned generally north at a 90° turn, then slowing down and then making several more 90° turns and proceeding east. After seeing this I knew what I was looking for and was able to pick up at least five more of these objects. Being skeptical, I did my best to see them as either dandelion seeds or other small particles close to the surface of the earth rather than large objects at extreme distance. However, after keeping them in sight long enough to study their appearance they definitely seemed to be very high. I won’t make an estimate of the height since I did not know their size. All of these appeared in the west and proceeded east at what appeared to be an extremely high rate of speed.”   I submit that this Air Force lieutenant was not incompetent, but rather that his manner of reporting — as far as it went — was commendable and that his report, made in good faith, is therefore entitled to a hearing without prejudice or ridicule, but also, without fanfare, hysteria, and fantastic newspaper publicity.   I cautioned against the then prevalent attitude of ridicule, pointing out that the UFO phenomenon, which had generated vast public interest, represented an unparalleled opportunity to demonstrate to the public the operation of the scientific method in attacking a problem, and that “ridicule is not a part of the scientific method and the public should not be taught that it is.”   In those years and the following ones I repeatedly asked for the upgrading of the method of reporting UFO’s to the Air Force. In

[[11]]

  1960, in a hearing before Congressman Smart and his committee I urged “immediate reaction capabilities” in the investigation of UFO reports. The recommendation was applauded but not funded.   As the scientific climate grew more receptive in giving the UFO phenomenon a scientific hearing, I published a letter in “Science” (Oct. 21, 1966), not without difficulty, in which I pointed out the following general misconceptions regarding UFOs. I should like to have that letter made a part of the record.   (The letter referred to is as follows 🙂

UFO’S MERIT SCIENTIFIC STUDY

  Twenty years after the first public furor over UFO’s (called “flying saucers” then) reports of UFO’s continue to accumulate. The Air Force has now decided to give increased scientific attention to the UFO phenomenon. Thus I feel under some obligation to report to my scientific colleagues, who could not be expected to keep up with so seemingly bizarre a field, the gist of my experience in “monitoring the noise level” over the years in my capacity as scientific consultant to the Air Force. In doing so, I feel somewhat like a traveler to exotic lands and far. away places, who discharges his obligation to those who stayed at home by telling them of the strange ways of the natives.   During my long period of association with the reports of strange things in the sky, I expected that each lull in the receipt of reports signaled the end of the episode, only to see the activity renew; in just the past two years It has risen to a new high. Despite the fact that the great majority of reports resulted from misidentifications of otherwise familiar things, my own concern and sense of personal responsibility have increased and caused me to urge the initiation of a meaningful scientific investigation of the residue of puzzling UFO cases by physical and social scientists. I have guardedly raised this suggestion in the literature [1] and at various official hearings, but with little success. UFO was a term that called forth buffoonery and caustic banter; this was both a cause and an effect of the lack of scientific attention. I speak here only of the puzzling reports; there is little point to concern ourselves with reports that can be easily traced to balloons, satellites, and meteors. Neither is there any point to take account of vague oral or written reports which contain few information bits. We need only be concerned with “hard data,” defined here as reports, made by several responsible witnesses, of sightings which lasted a reasonable length of time and which were reported in a coherent manner.   I have strongly urged the Air Force to ask physical and social scientists of stature to make a respectable, scholarly study of the UFO phenomenon. Now that the first firm steps have been taken toward such a study, I can set forth something of what I have learned, particularly as it relates to frequently made misstatements about UFO’s. Some of these statements which lead to misconceptions are:

  1. Only UFO “buffs” report UFO’s. The exact opposite is much nearer the truth. Only a negligible handful of reports submitted to the Air Force are from the “true believers,” the same who attend UFO conventions and who are members of “gee-whiz” groups. It has been my experience that quite generally the truly puzzling reports come from people who have not given much or any thought to UFO’s.

 

  1. UFO’s are reported by unreliable, unstable, and uneducated people. This is, of course, true. But UFO’s are reported in even greater numbers by reliable, stable, and educated people. The most articulate reports come from obviously intelligent observers; dullards rarely overcome their inherent inertia toward making written reports.

 

  1. UFO’s are never reported by scientifically trained people. This is unequivocally false. Some of the very best, most coherent reports have come from scientifically trained people. It is true that scientists are reluctant to make a public report. They also usually request anonymity which is always granted.

 

  1. UFO’s are never seen at close range and are always reported vaguely. When we speak of the body of puzzling reports, we exclude all those which fit the above description. I have in my files several hundred reports which are fine brain teasers and could easily be made the subject of profitable discussion among physical and social scientists alike.

1 J. Opt. Soc. Amer. 43, 311 (1953).

[[12]]

  1. The Air Force has no evidence that UFO’s are extraterrestrial or represent advanced technology of any kind. This is a true statement but is widely interpreted to mean that there is evidence against the two hypotheses. As long as there are “unidentifieds,” the question must obviously remain open. If we knew what they were, they would no longer be UFO’s — they would be IFO’s. Identified Flying Objects! If you know the answer beforehand, it isn’t research. No truly scientific investigation of the UFO phenomenon has ever been undertaken. Are we making the same mistake the French Academy Sciences made when they dismissed stories of “stones that fell from the sky”? Finally, however, meteorites were made respectable in the eyes of science.

 

  1. UFO reports are generated by publicity. One cannot deny that there is a positive feedback, a stimulated emission of reports, when sightings are widely publicized, but it is unwarranted to assert that this is the whole cause of high incidence of UFO reports.

 

  1. UFO’s have never been sighted on radar or photographed by meteor or satellite tracking cameras. This statement is not equivalent to saying that radar, meteor cameras, and satellite tracking stations have not picked up “oddities” on their scopes or films that have remained unidentified. It has been lightly assumed that although unidentified, the oddities were not unidentifiable as conventional objects.

For these reasons I cannot dismiss the UFO phenomenon with a shrug. The “hard data” cases contain frequent allusions to recurrent kinematic, geometric, and luminescent characteristics. I have begun to feel that there is a tendency in 20th-century science to forget that there will be a 21st-century science, and indeed, a 30th-century science, from which vantage points our knowledge of the universe may appear quite different. We suffer perhaps, from temporal provincialism, a form of arrogance that has always irritated posterity.   J. ALLEN HYNEK, Dearborn Observatory, Northwestern University, Evanston, Ill. One great misconception is that only UFO buffs report UFO’s; quite the opposite is the case, as is the misconception that the most baffling reports come from unreliable, unstable, and uneducated people. Most reports of this baffling sort which I at least receive in my mail, are remarkably articulate.   Other misconceptions are that UFO’s are never reported by scientifically trained people, are never seen at close range, have never been detected on radars, and have never been recorded by scientific cameras.   It is well to remind ourselves at this point of the definition of an UFO: those aerial phenomena reports which continue to defy explanation in conventional scientific terms, even after appropriate study. There is no point to be interested in anything else; lights at night which might be aircraft, balloons, meteors, or satellite re-entries all these fit more readily into the category of IFO’s or identified flying objects.   In other words, only truly unidentified cases should be of interest. The Air Force has its own definition of an unidentified case, and it has many hundreds in its files. The Air Force calls a sighting unidentified when a report apparently contains all pertinent data necessary to suggest a valid hypothesis concerning the cause or explanation of the report but the description of the object or its motion cannot be correlated with any known object or phenomena. .   It is most logical to ask why do not the unidentified in the Air Force files call forth investigative efforts in depth and of wide scope. The answer is compound: the Air Force position is that there is no evidence that UFO’s represent a threat to the national security: consequently it follows that it is not their mission to be scientifically curious about the hundreds of unidentified cases in their own files.

[[13]]

  It may be that, properly investigated, many of the Air Force unidentifieds would turn out to be IFO’s after all, but it is illogical to conclude that this would be true of all unidentified reports. As long as unidentified cases exist, thus bona fide UFO’s according to definition, we don’t know what they are, and these should represent a remarkable challenge to science and an open invitation to inquiry.   But so powerful and all-encompassing have the misconceptions among scientists been about the nature of UFO information that an amazing lethargy and apathy to investigation has prevailed. This apathy is unbecoming to the ideals of science and undermines public confidence.   Now it is of interest to report that in just the past few years, probably because of the persistent flow of UFO reports from this and many other countries (one could base his whole plea for a major investigative effort solely on the reports of the years 1966 and 1967) there has been a growing but unheralded interest on the part of more and more scientists, engineers, and technicians in doing something positive about the UFO problem. To this growing body of qualified people it seems increasingly preposterous to allow another two decades of confusion to exist.   The feeling is definitely on the increase that we should either fish or cut bait, that we should mobilize in earnest adequate groups of scientists and investigators, properly funded, adopt a “we mean business” attitude, or drop the whole thing. My recommendation is to fish.   As a scientist I can form conclusions from and act upon only reliable scientific data. Such data are extremely scarce in the UFO field for reasons already pointed out: it has never been considered worthwhile to improve the data-gathering process because the whole subject has been prejudged. Even as a scientist, however, I am permitted a scientific hunch, and that hunch has told me for some time, despite the tremendous muddiness of the scientific waters in this area, the continued reporting from various parts of the world of unidentified flying objects, reports frequently made by people of high repute who would stand nothing whatever to gain from making such reports, that there is scientific paydirt in the UFO phenomenon — possibly extremely valuable paydirt — and that therefore a scientific effort on a much larger scale than any heretofore should be mounted for a frontal attack on this problem.   In saying this I do not feel that I can be labeled a flying saucer “believer” — my swamp gas record in the Michigan UFO melee should suffice to quash any such ideas — but I do feel that even though this may be an area of scientific quicksand, signals continue to point to a mystery that needs to be solved. Can we afford to overlook something that might be of great potential value to the Nation?   I am reminded of the old story of the member of Parliament who visited Faraday’s laboratory where he was at work on early experiments on electrical induction. When asked of what possible value all this might have, Faraday replied, “Sir, someday you may be able to tax it.”   Apart from such inducements, I have the following recommendations to make: first, that a mechanism be set up whereby the problem posed by the reports from all over the world, but especially by those in the United States, from people of high credibility, can be adequately

[[14]]

  studied, using all methods available to modern science, and that the investigation be accorded a proper degree of scientific respectability and an absence of ridicule so that proper investigations can be carried out unhampered by matters not worthy of the ideals of scientific endeavor. I might suggest that this could be accomplished by the establishment, by the Congress, of a UFO Scientific Board of Inquiry, properly funded, for the specific purpose of an investigation in depth of the UFO phenomenon.   Secondly, I recommend that the United States seek the cooperation of the United Nations in establishing a means for the impartial and free interchange among nations of information about, and reports of, unidentified flying objects — a sort of international clearinghouse for the exchange of information on this subject. For, since the UFO phenomenon is global, it would be as inefficient to study it without enlisting the aid of other nations as it would be to study world meteorology by using weather reports from one country alone.   Now, it may be well to remind ourselves at this point, that the UFO problem may not lend itself to an immediate solution in our time. The problem may be far more complex than we imagine. Attempts to solve it may be no more productive than attempts to solve the problem of the Aurora Borealis would have been 100 years ago.   The cause of northern lights could not have been determined in the framework of the science of 1868. Scientific knowledge in those days was not sufficient to encompass the phenomenon.   Similarly, our scientific knowledge today may be grossly insufficient to encompass the problem posed by UFO’s. A profound scientific obligation exists, nonetheless, to gather the best data possible for scientific posterity.   To summarize: in the course of 20 years of study of UFO reports and of the interviewing of witnesses, I have been led to a conclusion quite different from the one I reached in the very first years of my work. At first I was negatively impressed with the low scientific content of UFO reports, with the lack of quantitative data, with the anecdotal nature of the reports, and especially with the lack of hardware, of unimpeachable photographs, and with the lack of instrumental recordings.   I am still aware of the paucity of truly hard-core data — but then, no effort has really been made to gather it. Nonetheless, the cumulative weight of continued reports from groups of people around the world whose competence and sanity I have no reason to doubt, reports involving close encounters with unexplainable craft, with physical effects on animals, motor vehicles, growing plants, and on the ground, has led me reluctantly to the conclusion that either there is a scientifically valuable subset of reports in the UFO phenomenon or .that we have a world society containing people who are articulate, sane, and reputable in all matters save UFO reports.   Either way, I feel that there exists a phenomenon eminently worthy of study. If one asks, for what purpose, I can only answer — how does one ever know where scientific inquiry will lead. If the sole purpose of such a study is to satisfy human curiosity, to probe the unknown, and to provide intellectual adventure, then it is in line with what science has always stood for.

[[15]]

  Scientific inquiry has paid off, even though pioneers like Faraday, Curie, Hahn, Pasteur, Goddard, and many others little realized where the paths they blazed would lead. As far as UFO’s are concerned, I believe we should investigate them for the simple reason that we want to know what lies behind this utterly baffling phenomenon even more simply, we want to find out what it’s all about.   Thank you.   ——————————————————————————– Mr. Roush. Thank you, Dr. Hynek.   Although we have reserved the latter part of the afternoon for our roundtable discussion, the Chair is well aware the Members of Congress, because of other duties, may not find it possible to be here during that time.   If any of my colleagues do have questions and can keep them brief, which I realize is impossible, I will entertain those questions at this time. But keep in mind that we have two more papers this morning, and three this afternoon. Mr. Hechler. Mr. Chairman. Mr. Roush. Mr. Hechler. Mr. Hechler. First I would like to commend you, Mr. Roush, for your initiative in setting up this symposium.   I would like to ask you, Dr. Hynek, whether you consider this scientific board of inquiry which you outlined as a sort of a one-shot thing which would make its report, or do you consider this to be a continuing body that could examine, as the Air Force has, reports and analyze them? And with this question, I would like to ask if your assumption is that the Air Force, because of its emphasis on national security, has really not measured up to a thorough scientific analysis of UFO’s? Dr. Hynek. Well, in answer to the first part of that question, sir, I would say I don’t believe in a problem as complex as this the one-shot approach would be sufficient. I think there should be this board of inquiry which should be a continuing board in the same sense that we have, I presume, boards of study for world population problems, of pollution problems, of world health, and so forth.   The letter that came with the invitation to speak here, strongly stated that we would not discuss the Air Force participation in these matters, and I would like to therefore not speak to that point. Mr. Roush. Mr. Rumsfeld. Mr. Rumsfeld. Because of the fact it does look as though we will have a busy afternoon on the floor, I very likely will not be present for the remainder of the discussion. I would like to express the hope the other members of the panel might at some point comment on the two recommendations that Dr. Hynek has set forth in his paper. Further, I would hope that each member of the panel, during the afternoon session, might address himself to the questions of priorities.   Assuming that there is some agreement with Dr. Hynek’s conclusion that this is an area worthy of additional study, then the question for Congress, of course, becomes what is the priority? This is a rather unique situation in that it is a scientific question that has reached the public prior to the time that anything beneficial can even be imagined. In many instances a scientific effort is not widely known to the public until it is successful.

[[16]]

Each of you are experts in one or more disciplines. I am sure there are a number of things on your shopping lists for additional funding. I would be interested to know how this effort that is proposed here might fit into your lists of priorities.   Thank you, Mr. Chairman. Mr. Roush. Thank you, Mr. Rumsfeld.   Mr. Miller. Chairman Miller. Doctor, you mentioned a number of things — population studies at least. A great many of these are carried out not by Government directly, but in the National Science Foundation or through the National Academy of Sciences or scientific bodies themselves.   Do you think, I merely offer this as a suggestion, perhaps the scientific community try to encourage NSF or the scientific societies dealing in this field to take the initiative in doing this, rather than to wait for Government to take the initiative? Dr. Hynek. I know, of course, most of the bodies you have mentioned are funded by the Government anyway. Most or a great part of our scientific research today has to be so funded. Private sources are certainly not sufficient. And, therefore, I think it is rather academic, really, to worry too much about who does it. It is more a question of who is going to pay for it.   We have a rather interesting situation here, as Congressman Rumsfeld has already pointed out. This is one of those strange situations in which the cart is sort of before the horse. Generally this results in the scientific laboratories and the results of the studies of scientists finally come to the public attention, but here we have the other situation. it is the public pressure, the public wants to know actually, more than the scientists, at the moment. So you are facing public pressures, even, definitely more than scientific pressures at the moment. Chairman Miller. Unfortunately in some of our problems, for example the NASA problems, where the public is indifferent, the matter of waste disposal, pollution, health, and these things. They are quite indifferent to them, and it takes a lot of effort to get them interested in them sometimes.   The committee has studied this on several occasions, but we have generally had a group of the scientific community behind us to give pressure, to bring pressure, to get some of these things done. Dr. Hynek. I think we will see, sir, in this testimony today that you will find a corps of scientists stand ready to do this. In fact, as I mentioned in my testimony, I have private information from a very large number of scientists who are interested. Chairman Miller. I think this one of the values of the symposium. Mr. Roush. Are there other questions or comments ?   (No response.)   Our next participant is Dr. James E. McDonald. Dr. McDonald is presently with the University of Arizona. He is a senior physicist, Institute of Atmospheric Physics, the University of Arizona, and has had a long and distinguished career as a scientist.   Dr. McDonald, we are pleased to have you as one of our participants. You may proceed.

STATEMENT OF DR. JAMES E. MCDONALD, SENIOR PHYSICIST, INSTITUTE OF ATMOSPHERIC PHYSICS, AND PROFESSOR, DEPARTMENT OF METEOROLOGY, THE UNIVERSITY OF ARIZONA, TUCSON, ARIZ. Dr. McDonald. Thank you, Mr. Roush.   I am very pleased to have this chance to make some comments and suggestions based on my own experience to the committee, and I do wish to commend the Committee on Science and Astronautics for taking this first, and I hope very significant step, to look at the problem that has puzzled many for 20 years.   As Dr. Hynek has emphasized in his remarks, it is one of the difficulties of the problem we are talking about today that the scientific community, not just in the United States but on a world basis, has tended to discount and to regard as nonsense the UFO problem. The fact that so much anecdotal data is involved has understandably discouraged many scientists from taking seriously what, in fact, I believe is a matter of extraordinary scientific importance.   I have been studying now for about 2 years, on a rather intensive basis, the UFO problem. I have interviewed several hundred witnesses in selected cases, and I am astonished at what I have found.

[[18]]

  I had no idea that the actual UFO situation is anything like what it really appears to be.   There is a certain parallel between Dr. Hynek’s slow recognition of the problem and my slow recognition of the problem. I have been curious about UFO’s in a casual way for 10 or 20 years and have even checked cases in the southern Arizona area off and on rather casually, mainly encountering sincere laymen who do not recognize an aircraft strobe light, or Venus, or a bright fireball, when they see them. It is quite true that many persons misidentify natural phenomena; and my experience was mainly but not entirely limited to that sort of case.   About 2 years ago I became more than casually curious for several reasons that are not too relevant here, and began to spend much more time and very quickly changed my notions about the problem. I visited Wright-Patterson Air Force Base, saw their very impressive and surprising UFO files, the pattern of which is entirely different from what I had imagined.   At the same time, I contacted a number of private investigating UFO groups, one of the best and most constructive located here in Washington, the National Investigations Committee on Aerial Phenomena; contacted another one of the large national groups, the Aerial Phenomenon Research Organization, and found again somewhat to my surprise, that these amateur groups operating on a shoestring basis, and frequently scorned by us scientists, were, in fact, doing really a rather good investigative job within their resources, and had compiled in their files, for instance in NICAP, on the order of 10,000 or 12,000 cases, many of which I have subsequently checked, and all of which imply a problem that has been lost from sight, swept under the rug, ignored, and now needs to be very rapidly brought out into the open as a problem demanding very serious and very high-caliber scientific attention.   I wish to emphasize that. We must very quickly have very good people looking into this problem, because it appears to be one of very serious concern. We are dealing here with inexplicable phenomena, baffling phenomena, that will not be clarified by any but the best scientists.   The scope of my remarks this morning, and the scope of my more detailed remarks in my prepared statement which has been submitted, deal with two broad areas:   I have been asked to summarize the results of my interviewing of witnesses in the last 2 years, what I found, the problems I have encountered and so on; and, secondly to address myself to the categories of past explanations of UFO sightings, that hinge on my own field of atmospheric physics.   Let me turn very briefly to my experience. In the past 2 years I have been able to devote a substantial part of my time to this problem. I have mainly concentrated on witnesses in UFO sightings that have already been checked by some of the independent groups; that is, I was no longer, in the last 2 years, dealing with original raw data where it was primarily misidentified phenomena, but rather, I was dealing with presifted, presorted data, leaning very heavily on groups like NICAP and APRO, and other groups in this country and other groups abroad for my leads and background material.

[[19]]

  I have also had a chance to interview 75 or 80 witnesses in Australia, New Zealand, and Tasmania, when I was down in that area last summer. There were various kinds of atmospheric explanations that bad been invoked in Australian cases. I must say that many of them are just as reasonable from the scientific point of view as many that we have heard in this country. But primarily I found in Australia that the nature of the sightings is similar to those in the United States, disk-like objects, cigar-shaped objects, objects without wings, without evident means of propulsion, frequently hovering without any sound, sometimes making sounds, hovering over cars, stopping cars, as Dr. Hynek has pointed out, causing interference with the ignition system, and the same kind of public reluctance to report was very evident.   I want to emphasize, as one of the very important misconceptions that has been fostered, that instead of dealing with witnesses who are primarily looking for notoriety, who want to tell a good story, who are all out to gain attention, it is generally quite the opposite. And this is true in Australia, too. People are quite unwilling to tell you about a UFO sighting, afraid acquaintances would think they nave “gone around the bend,” as Australians put it. Over and over you encounter that. People are reluctant to report what they are seeing. There is a real ridicule lid that has not been contrived by any group, it just has evolved in the way the whole problem has unfolded. This is not entirely new in science. It has occurred before.   I am sure a number here at the speakers’ table are familiar with an interesting chapter in science years ago when meteorites, out of which NASA and many scientists around the world now get a very large amount of useful scientific information, were scorned and scoffed as unreal. It was regarded as nonsense that peasants were telling stories about stones falling out of the sky. The efforts of a few scientists to take a look at the problem and to get some initial data simply were ignored until a very unusual but very real event occurred in northern France, a meteorite shower. So they sent an eminent academician out to have a look at what these people were talking about, and by golly, the peasants appeared to be right. Everybody in the village, the prefect of police, the local administrators, all the peasants, had seen stones fall out of the sky, and for the first time the French Academy deigned to take a look at the problem. Meteoritics was born.   Here we now face a very similar situation in science. We have tended to ignore it because we didn’t think it made sense. It definitely defies any explanation, and hence the situation has evolved where we can’t get going because we aren’t already going.   The scientific community as a whole won’t take this problem seriously because it doesn’t have scientific data. They want instrumental data.   Why don’t they have instrumental data ? Because the scientists don’t take it seriously enough to get the scientific data. It is like the 20-year-old who can’t get a job because he lacks experience, and he lacks experience because he hasn’t had a job. In the same way you find the scientist wishing you would give him good hard meter readings and magnetometer traces, and so on: but we don’t have it yet because the collective body of scientists, including myself, have ignored UFO’s.

[[20]]

  Turning to some of the highlights of my interviewing experience, I first mention the “ridicule lid.” We are not dealing with publicity seekers. We are not, and I here concur with Dr. Hynek’s remarks, we are not dealing with religiosity and cultism. Those persons aren’t really the least bit interested in observations. They have firm convictions entirely independent of observations. They do not cause noise that disturbs the real signal at all.   General Samford of the Air Force put it well, 16 years ago. General Samford, then Director of Intelligence, said, and I would concur 100 percent, “Credible observers are observing relatively incredible objects.” That was said 16 years ago, and it is still occurring.   I will touch in a moment or two on a sighting in Mr. Pettis’ district that very well illustrates that, a sighting this year in Redlands, Calif., which I think Dr. Harder may be able to tell still more about.   Another characteristic in interviewing the witnesses is the tendency for the UFO witness to turn first not to the hypothesis that he is looking at a spaceship, but rather it must be an ambulance out there with a blinking red light or that it is a helicopter up there. There is a conventional interpretation considered first; only then does the witness get out of the car or patrol car and realize the thing is stopped in midair and is going backwards and has six bright lights, or something like that. Only after an economical first hypothesis does the witness, in these impressive cases, go further in his hypotheses, and finally realize he is looking at something he has never seen before.   I like Dr. Hynek’s phrase for this, “escalation of hypotheses.” This tendency to take a simple guess first and then upgrade it is so characteristic that I emphasize it as a very important point.   Then, looking at the negative side, all of us who have checked cases are sometimes in near anguish at the typical inability of the scientifically untrained person to estimate angles, to even understand what you are asking for when you ask for an angular estimation. We are all aware of the gross errors in distances, heights, and speeds so estimated.   And I would emphasize to those who cite jury trial experience that the tendency for a group of witnesses to an accident to come in with quite different accounts, must not be overstressed here. Those witnesses don’t come in from, say, a street corner accident and claim they saw a giraffe killed by a tiger. They talk about an accident. They are confused about details. There is legally confusing difference of timing and distance, and so on; but all are in agreement that it was an auto accident.   So also when you deal with multiple-witness cases in UFO sightings. There is an impressive core of consistency; everybody is talking about an object that has no wings, all of 10 people may say it was dome shaped or something like that, and then there are minor differences as to how big they thought it was, how far away, and so on. Those latter variations do pose a very real problem. It stands as a negative factor with respect to the anecdotal data, but it does not mean we are not dealing with real sightings of real objects.   Then there’s the very real but not terribly serious problem of the hoaxers, fabricators, liars, and so on. You do encounter cases from time to time where you end up thinking, well, this person has some

[[21]]

  reason to have invented the whole story. Sometimes it is fairly apparent. Sometimes it takes a lot of digging to prove it.   I might say here that the independent investigative groups have done an excellent job. It takes a knowledge of human characteristics, not scientific expertise to detect lies and hoaxes.   Then there is the problem that you always have to be sure in talking with witnesses that you are not dealing with somebody already very enthusiastic about UFO’s. You have to try to establish, and this is not always easy, whether he has prior knowledge of the whole UFO literature. Are you dealing with somebody who is just telling you again what he has read in a recent magazine in the barber chair?   I emphasize that my experience is that again and again you find people who were not really interested in UFO’s until they saw one themselves. Then they suddenly became very, very concerned, as one more member of the public who has become a UFO witness; and in this body of citizens there are some very distressed persons who wish that the scientific community, or the Government, were doing something about this problem.   The types of objects that are being seen, and I state the word “objects” not “hazy lights,” are spread over quite a range of types, a baffling range.   I want to use that word many times, because it speaks for my experience. The UFO problem is baffling. But there is a predominance of disc-shaped objects and elongated cigar-shaped objects, objects without wings, appendages, tails, and that sort of thing. Typically, wingless objects, disc- and cigar-shaped.   The same type of observations have been coming from all parts of the world, and have been for a number of years. My direct interviews with a witness in Australia speak for that global pattern.   Another characteristic that emerges is a quite fluctuatory frequency of sightings. Right now, in the past few months, there have not been very many really impressive cases that have come up; but last fall, for example, England had a wave of sightings which was unprecedented in the English experience, that led, for example, to a BBC documentary that has just been produced. It led also to a recently published study, that I got only a couple of weeks ago from the Stoke-on-Trent area in Staffordshire, 70 sightings in about a 2½ month period in this area. It happens that one of my colleagues is an English physicist from that very area. As he points out, these are no-nonsense people who are not airy-fairy types that would be on LSD), or seeing ghosts in the sky.   He is puzzled, and I am puzzled.   Well, there are many questions that are asked by skeptical scientists, skeptical members of the public; and skepticism, as Mark Twain said, is what gets you an education.   There are questions like. “Why aren’t UFO’s seen abroad?” “Why aren’t UFO’s seen by airline pilots?” “Why aren’t UFO’S seen by crowds of people rather than by lone individuals?” “Why aren’t they tracked by radar?” “Why don’t weather observers and meteorologists see UFO’s?”   “Why aren’t there sonic booms, or why aren’t there crashed UFO’s?”   Finally, a very frequently raised question, “If the UFO’s are from somewhere else,’ if they are really devices that represent some high

[[22]]

  civilization, why no contact?” This is a question that comes up again and again, since most persons who know enough about the UFO problem to realize there must be something there, cannot, in their first view of the problem, visualize a visitation from elsewhere, surveillance, or what have you, without contact.   I want to return to that point later, but I wish to emphasize that that is a fallacious question. If we were under surveillance from some advanced technology sufficiently advanced to do what we cannot do in the sense of interstellar travel, then, as Arthur Clarke has put it quite well, quoted in Time magazine the last week, we have an odd situation. Arthur Clarke points out that any sufficiently advanced technology would be indistinguishable from magic. How well that applies to UFO sightings. You have a feeling you are dealing with some very high technology, devices of an entirely real nature which defy explanation in terms of present-day science. To say that we could anticipate the values, reasons, motivations, and so on, of any such system that has the capability of getting here from somewhere else is fallacious.   That is a homocentric fallacy of the most obvious nature, yet it is asked over and over again.   In my prepared statement I will be able to cover more of these points, of course.   The heart of the problem lies in citing cases, and I have investigated, personally, on the order of 300 cases dealing with key witnesses. I have looked as carefully as I can for all reasonable explanations.   There are many cases that fall apart when you investigate them. Then there are far too many that resist the best analysis that many of us have been able to subject them to.   Let me just cite briefly, to take a recent case rather than an old one, the instance at Redlands, and perhaps Dr. Harder can fill you in in more detail.   On February 4 of this year, at 7:20 in the evening, over a residential area in that city of population 30,000, a disc was seen. Twenty witnesses interviewed by University of Redlands’ investigators, described it as having “windows” or “ports” or something of that sort. They interviewed a little over half a dozen of them and all saw something on the bottom that they described as “looking like jets.”   This object was hovering at an estimated height of about 300 feet. The estimates vary, but it came out about 300 feet. The citizens had gone out in the street because dogs were barking and, because they had heard an unusual noise, and pretty soon there were people all up and down the street. It was estimated that more than 100 witnesses were involved, and 20 were directly interviewed.   Here was an object seen by many persons. It hovered, then shot up to about double the height, hovered again, and moved down across Redlands a short distance, hovered once again, and then took off rapidly to the northwest.   This case has not received any scientific attention beyond this investigation by Dr. Philip Seff and his colleagues. It has not received public notoriety. This was, in fact, only reported in a short column in the local paper and not on the wires anywhere. That happens over and over again.   Here, for example, are the reports for one month of last fall, clipping-service coverage on the things that get local coverage, but

[[23]]

  don’t get on the wires, because in the present climate of the opinion, wire editors, like scientists, Congressmen, and the public at large, feel sure there is nothing to all this, and they don’t put them on the wires. You have to go right to the local town to get press coverage in most cases.   The Redlands, February 1968, case illustrates that very well. Once in a while a case will get on the wires and receive national attention, but by and large, one just doesn’t read about these cases in other parts of the country, because wire services don’t carry them.   Let me tell you another case that answers the questions: “Why aren’t there multiple witnesses?” “Why aren’t they seen in cities?” “Why aren’t these ever seen in the daytime?”   It is true that there is a preponderance of nighttime sights. Maybe this is merely a matter of luminosity.   It is also true that there seem to be more reports from rather remote areas, say desert areas or swampy areas, than in the middle of cities. But there are city observations. And it is also true there are more individual witness cases than sightings by large crowds. But in every instance there are striking exceptions to this.   In New York City, on November 22, 1966, a total of eight witnesses, members of the staff of the American Newspaper Publishers Association, were the witnesses in a good case. I interviewed William Leick, of that staff, the manager of the office there. I heard about it through a NICAP report. It did not appear in the papers, as I will mention. William Leick had been looking out the window, saw an object over the U.N. building. It was hovering, and as he talked to a colleague he realized there was something odd about it, so they walked out on the terrace. Soon they had six others out on the terrace. This was at 4:30 in the afternoon. It was kind of a cushion-shaped object, as he described it, and had no wings. It was rocking a little from time to time, blinked in the afternoon sun a little bit, had kind of an orange glow. All eight were watching, and after it hovered for several moments it rose vertically and then took off at high speed. There is an example of midtown sighting in New York where the witnesses are staff members of a responsible organization. Leick, himself, had been trained in intelligence, in World War II. There is no reason at all to think he and his colleagues would invent this.   They did call a New York paper, but to say they weren’t the least bit interested. There was no report published in a New York paper. Next they called a local Air Force office but no one came to investigate it. It came to my attention because one of the members of the staff knew of NICAP and sent NICAP a report.   This sort of thing has happened over and over again. The ridicule lid keeps these out of sight; too many of them are occurring to delay any longer in getting at this problem with all possible scientific assistance.   A famous multiple-witness instance occurred in Farmington, N. Mex., on March 17, 1950. I interviewed seven witnesses there. A very large number of objects were involved. There were several different groups of objects, all described as disc-shaped objects. They were explained as Skyhook balloons, officially, so I checked into that.   I finally established that there was no Skyhook balloon released anywhere in the United States on or near that day. The witnesses included

[[24]]

  some of the leading citizens in the town. It was reported nationally at that time but was soon forgotten.   I have interviewed one of the witnesses in a Washington State sighting, at Longview, Wash., July 3, 1949. An air show was being held and someone spotted the UFO because there was a sky-writing aircraft overhead that some people were watching. They spotted the first of three disc-like objects that came over Longview that morning. The person whom I interviewed is a former Navy commander, Moulton B. Taylor. He was the manager of the air show, so he got on the public address system and got everybody to look at this object before it crossed the skies. It was fluttering as it went across the sky. There were pilots, engineers, police officers, and Longview residents in the audience. Many had binoculars. Taylor estimated it to be about 10 minutes of arc in diameter. Because the aircraft was still skywriting people continued to watch the sky. Two successive objects of the same type flew over in the next 20 minutes. A total of three objects came over, and they were from three different directions: one from the north, one from the northwest, and one almost from the west, quite clearly ruling out an explanation like balloons, which became the official explanation. There were no balloon stations anywhere near Longview, Wash., as a matter of fact, and the balloon explanation is quite inadequate.   Here we have a case of over a hundred witnesses to the passage of a wingless object moving at relatively high velocity. When the second and third objects went over, someone had the presence of mind to time the fluttering rate — it was 48 per minute.   Here again we have a multiple-witness case, a daytime sighting case, and one which you can’t quickly write off.   If time permitted I would talk about a number of radar cases. One of the most famous is the Washington National Airport sighting. On July 19, 1952, CAA radars and Andrews Air Force radars tracked unknowns moving at variable speeds from 100 miles an hour to over 800 miles an hour, and a number of airline pilots in the air saw these, and were in some instances vectored in by the CAA radar people, and then saw luminous objects in the same area that they showed on radar up near Herndon and Martinsburg.   I talked to five of these CAA people. One can still go back and check these old cases, I emphasize. I also talked to four of the airline pilots who were in the air at the time. I have gone over the quantitative aspects of the official explanation that this was ducting or trapping of the radar beams. That is quite untenable. I have gone over the radiosonde, computed the radar refractive index gradient, and it is nowhere near the ducting gradient.   Also, it is very important that at one time three different radars, two CAA and one Andrews Air Force Base radar, all got compatible echoes. That is extremely significant.   And finally from a radar-propagation point of view, the angles of propagation, radar and visual, were far above any values that would permit trapping, which makes this a case which is not an explained case. It was an instance of unidentified aerial objects over our Capital, I believe.   One could go on with many cases. I want to just briefly touch two categories of atmospheric explanations that have been rather widely discussed, and close with that.

[[25]]

  Meteorological optics is a subject, that I enjoy and have looked into over the years rather carefully, and I must express for the record my very strong disagreement with Dr. Donald H. Menzel, former director of Harvard Observatory, whose two books on the subject of UFO’s lean primarily on meteorological explanations. I have checked case after case of his, and his explanations are very, very far removed from what are well-known principles and quantitative aspects of meteorological optic objects. He has made statements that simply do not fit what is known about meteorological objects.   I would be prepared to talk all day on specific illustrations but time will not permit more.   Secondly, there has more recently been a suggestion made by “Aviation Week” Senior Editor Philip J. Klass, that the really interesting UFO’s are atmospheric-electrical plasmas of some type similar to ball lightning, but perhaps something different, something we don’t yet understand but are generated by atmospheric processes.   The first time anyone tried the ball lightning hypothesis was in Air Force Project Grudge, back in 1949. The Weather Bureau was asked to do a special study of ball lightning. I recently got a declassified copy of that, and the Air Force position at that time, and since then was that ball lightning doesn’t come near to explaining these sightings. I concur in that. When you deal with multiple-witness cases involving discs with metallic luster, definite outline, seen in the daytime, completely removed from a thunderstorm, perhaps seen over center Manhattan, or perhaps in Redlands, Calif., they are not ball lightning or plasmas.   In weather completely unrelated to anything that could provide a source of energy, the continuous power source required to maintain a plasma in the face of recombination and decay of a plasma, Klass’ views just do not make good sense.   It is just not reasonable to suggest that, say the BOAC Stratocruiser that was followed by six UFO’s for 90 miles up in the St. Lawrence Valley in 1954 was followed by a plasma, or that these people in Redlands were looking at a plasma, or that the 20 or so objects that went over Farmington were plasmas.   One of the most characteristic features of a plasma is its very short lifetime and exceedingly great instability, as some of your members will know from your contact with fusion research problems. The difficulty of sustaining a plasma for more than microseconds is a very great difficulty. To suggest that clear weather conditions can somehow create and maintain plasmas that persist for many minutes, and fool pilots with 18,000 flight hours into thinking that they are white- and red-domed discs, to take a very famous case over Philadelphia where the pilot thought he was about 100 yards from this dome-disc, is unreasonable. It is not a scientifically well-defended viewpoint.   To conclude, then, my position is that UFO’s are entirely real and we do not know what they are, because we have laughed them out of court. The possibility that these are extraterrestrial devices, that we are dealing with surveillance from some advanced technology, is a possibility I take very seriously.   I reach that hypothesis, as my preferred hypothesis, not by hard fact, hardware, tailfins, or reading license plates, but by having examined

[[26]]

  hundreds of cases and rejected the alternative hypothesis as capable of accounting for them.   I am afraid that this possibility has sufficiently good backing for it, despite its low a priori ability, that we must examine it. I think your committee, with its many concerns for the entire aerospace program, as well as our whole national scientific program, has a very special reason for examining that possibility. Should that possibility be correct, if there is even a chance of its being correct, we ought to get our best people looking at it. Instead, we are collectively laughing at this possibility.   To meet Mr. Rumsfeld’s request, let me remark on Dr. Hynek’s two recommendations. I strongly concur in the need for some new approach. I am sure Dr. Hynek was not suggesting there be one single UFO committee. In fact, he said, “not a one-shot approach.” A pluralistic approach to the problem is needed here.   The Defense Department is already supporting some work on it. NASA definitely has a need to look at this problem. We have to pay very serious attention to the problem and get a variety of new approaches.   The other point Dr. Hynek mentioned was that we try to look at this on a worldwide basis. This is crucially important. We are dealing with a real problem here, and I insist it is a global problem. We can study it in the United States, but if we ignore what is happening in France and England — one of the greatest UFO waves that ever occurred was in France — would be a serious mistake. I strongly urge that your committee consider holding rather more extensive Hearings in which a larger segment of the scientific community is given the opportunity to talk pro and con on the issue, hearings aimed at getting a new measure of scientific attention to this important problem.   Thank you. Mr. Roush. Thank you, Dr. McDonald, for your presentation. As we explained awhile ago, we are pressed for time. We are entertaining questions from members of the committee. Mr. Bell. Dr. McDonald, I want to compliment you on your interesting statement. But what leads you to believe that whatever these phenomena are, they are extraterrestrial?   What facts do you have? Dr. McDonald. May I say I wouldn’t use the word “believe.” I would say the “hypothesis” that these are extraterrestrial surveillance, is the hypothesis I presently regard as most likely.   As I mentioned, it is not hard facts in the sense of irrefutable proof, but dealing with case after case wherein the witnesses showed credibility I can’t impugn. That impresses me. These are not at all like geophysical or astronomical phenomena; they appear to be craft-like machine-like devices. I would have to answer you in terms of case after case that I and others have investigated, to make all this clear. It is this very large body of impressive witnesses’ testimony, radar-tracking data on ultra-high-speed objects sometimes moving at over 5,000 miles an hour, UFO’s, combined radar-visual sightings, and just too much other consistent evidence that suggests we are dealing with machine-like devices from somewhere else.

[[27]]

  Mr. Bell. Have there been pictures taken ? Dr. McDonald. Yes; there nave been pictures taken.   For instance, a photograph taken in Ohio, by an Air Force photo reconnaissance plane May 24, 1954. I recently have looked a little more closely at the data. This was explained as an undersun, but that idea is subject to quantitative observation. The angles just do not fit. There is a very important case at Edwards Air Force base with two witnesses, where they got photographs of the object. Unfortunately, in this case I have not seen the photo, but I have talked with the persons who took it. There are photographs, but not nearly as many as we would like. We would like to have lots of them. In a case in Corning, Calif., a police officer, one of five witnesses, had a loaded camera in his patrol car, 20 paces from where he watched the object, didn’t even think of getting his camera. He said he was too flabbergasted to think of it. That is a part of the problem. Mr. Roush. Mr. Hechler. Mr. Hechler. Have you examined any reports of communication by these objects ? Dr. McDonald. Yes; the problem of contact is very important. There is one category of contact, not in the sense of shaking hands, but rather light response. I have a file on several of these, and I’m looking for more. For instance, in Shamokin, Pa., Kerstetter is the name of the witness, he works for a bank in Shamokin. I talked to the president of the bank as to his reliability and got very good recommendations. Last year, he and his wife and family were in a car near a mountain ridge in Shamokin, saw a thing hovering over the mountain, like the flashing lights of a theater marquee. He had a flashlight. He didn’t know Morse code, but it really didn’t matter. He sent light flashes in various orders and he got lights back from the thing. That same thing happened in Newton, N.H., in August of last year, where several persons saw an object coming overhead. The same thought occurred to them and they signaled with a flashlight. It wasn’t Morse, it was dot dash dot, then dash dash dash, and it came back with no failure, replicated light signals. The same thing happened in West Virginia, where a pharmacist, named Sommers, did it with his headlights. When I was in Australia, I talked about some hunters out hunting kangaroo. A disk came over, one said “give them Morse”; the flash came back faithfully, and they left in a hurry. Is that contact? I don’t know. Nobody got any intelligence out of it either way, if you will pardon the whimsy. It would be terrible if in fact this was surveillance and our technology was represented by the Eveready flashlight. [Laughter.]   We may be flunking our exam. Mr. Roush. Mr. Downing. Mr. Downing. I’m interested in your testimony. On page 10 of your written statement, you say it is unfortunate no acceptable version of Reference 6 exists, though it has managed to get it into the status of limited acceptability.   Why is this not available? Dr. McDonald. Well, that was an Air Force document. This was completed in 1949. These were classified until just a few years back. No one could get access to them, because they were under DOD classification. But the 12-year rule expired, and Dr. Leon Davidson managed to get a copy.

[[28]]

  It is accessible in the sense that if I want to pay $90 for Xeroxes I can now get it. It is not published in the sense of being available to every library in the country. My Reference 7, which NICAP just published, is available to scientists all over the country. It is a matter of the Air Force having a policy of not publishing such items, and they were classified. I think the Moss committee and NICAP are to be highly praised to get out in the open Reference 7. Mr. Downing. Is there a reason why this is classified? Dr. McDonald. There is an understandable reason why the Air Force has had to classify this. An unidentified aerial object, on presumption, is hostile until proved otherwise. So there has been this unfortunate, but entirely understandable measuring of these two areas. The national defense mission of the Air Force has necessitated they have some part of the UFO problem inevitably, and they got it in the first instance. They have long since told us there is no hostility here, hence the scientific curiosities going unattended because it doesn’t fall under the defense mission, in other words to be transferred into NASA, NSF, or something like that. That does not mean the Air Force won’t continue to watch unidentified objects on the millisecond basis. But they not need worry about this other part of the problem. I think it is understandable, but needs changing. Mr. Roush. Mr. Pettis. Mr. Pettis. Mr. Chairman, Doctor.   I was a little bit interested in your observations about this UFO sighting in my hometown of Redlands.   I might observe that Redlands is a rather conservative community, when people in Redlands say they saw something, they saw something. I did not happen to be in Redlands that particular date, so I did not see this.   But I would like to observe this, that having spent a great deal of my life in the air, as a pilot, professional and private pilot, I know that many pilots and professional pilots have seen phenomena that they could not explain.   These men, most of whom have talked to me, have been very reticent to talk about this publicly, because of the ridicule that they were afraid would be heaped upon them, and I’m sure that if this committee were ever to investigate this, or bring them in here, there probably would have to be a closed hearing, Mr. Chairman.   However, there is a phenomena here that isn’t explained.   I think probably we ought to do a little looking into this, is my personal opinion. Mr. Roush. Mr. Ryan. Mr. Ryan. Yes, thank you, Mr. Chairman.   First I should like to commend you, Mr. Roush, for your interest in the subject matter, and the chairman of the full committee for having arranged for hearings into this problem.   I think it is important that this committee not waive its jurisdiction, but that it explore very carefully the proposals that have been made by the witnesses here, and that it have a continuing field of exploration into this whole question. I want to commend Dr. McDonald for having been persistent in presenting his views to the various members of the committee, helping to bring about these hearings.

[[29]]

  I wondered, Dr. McDonald, if you would care to evaluate the research project at the University of Colorado, and comment on that? Mr. Roush. Mr. Ryan, may I just say we had agreed that this was not the place to discuss that particular project, and that the purpose of the symposium was not to go into the activities of another branch of government, but rather to explore that as a scientific phenomena.   I’m sure that Dr. McDonald would be very happy to confer with you privately on this, but if you could show some restraint here, the Chair would be real grateful to you. Mr. Ryan. Well, let me rephrase my question.   In view of the fact that there has been a study conducted by a project in the Air Force, and the University of Colorado, do you believe there is anything further that should be done by any branch of the Government? Dr. McDonald. Emphatically, yes. Mr. Ryan. What would you recommend? Dr. McDonald. I think that we need to get a much broader basis of investigation of UFO’s, as I did say, a few moments ago, it would be very salutary to have a group in NASA looking at this problem, and to have some NASA support of independent studies. It would be very good for the National Science Foundation to support, say, some university people interested in it. It would be good to have the Office of Naval Research et cetera involved.   We don’t deal with many other important problems, space, or molecular biology or health without a pluralistic approach, a multiplicity of research programs. I don’t want to touch a frayed nerve here. This problem of duplication is sometimes lamented. But by and large I think you will agree we would gain from having a lot of different people with slightly different points of view going at every problem. At the moment everything is focused through one agency, and everything now hinges on that one particular program you have asked me about, and my answer was, we very definitely need some independent programs.   I am on record elsewhere than here in my specific views on that project. Mr. Ryan. Looking back at page 14, you wrote a letter to the National Academy of Sciences, concerning this project. Have you had any reaction from the National Academy of Sciences? Dr. McDonald. Yes, I received a letter from Dr. Seitz, saying for the time being we must let the Colorado project run its course. That was the gist of the answer. Mr. Roush. I would appreciate it, if we dispensed with that. Let me say that the National Academy is undertaking an evaluation of the University of Colorado project, and this will be published. Mr. Ryan. I’m suggesting maybe this committee should make an investigation of the University of Colorado project. Chairman Miller. That is something we don’t have authority to do here. Mr. Ryan. To what extent, Dr. McDonald, have sightings been picked up by radar, and what extent of those that have been picked up been explored? Dr. McDonald. Well, there are many such sightings, I dare say there are thousands of military radar sightings that were for the short

[[30]]

  period unidentified. Then they identify them. But here is an impressive number of both military and civilian radar sightings that defy radar explanation in terms of unknown phenomena. Most of these deficiencies are well understood, so one can be fairly sure that many of these unidentified radar cases have no conventional explanation.   In a case where a P-61 flew over Japan, back some years ago, made six passes at an unidentified object it was getting radar returns on, and the pilot saw it visually. Here you are dealing with an unknown. Then there was a case in Michigan where a ground radar detected an object at 600 miles an hour coming in over Saginaw Bay. The pilot got a radar return, and also saw a vast luminous object; the object turned in a very sharp 180 degree turn and went back, and eluded the F-94. Here you are dealing with a case where radar propagation anomalies will not explain it. There was one radar in the airplane at 20,000 feet and one radar on the ground, both showing the object. There are many cases like that which I could enlarge on. Mr. Ryan. Let me ask a further question: In the course of your investigation and your study of UFO sightings, have you found any cases where contemporaneously with the sighting of UFOs allegedly, there were any other events which took place, which might or might not be related to the UFO’s ? Dr. McDonald. Yes. Certainly there are many physical effects. For instance, in Mr. Pettis’ district, several people found the fillings in their mouth hurting while this object was nearby, but there are many cases probably on record of car ignition failure. One famous case, was at Levelland, Tex., in 1967. Ten vehicles were stopped within a short area, all independently in a 2-hour period, near Levelland, Tex. There was no lightning or thunder storm, and only a trace of rain. There is another which I don’t know whether to bring to the committee’s attention or not. The evidence is not as conclusive as the car stopping phenomenon, but there are too many instances for me to ignore. UFO’s have often been seen hovering near power facilities. There are a small number but still a little too many to seem pure fortuitous chance, of system outages, coincident with the UFO sighting. One of the cases was Tamaroa, Ill. Another was a case in Shelbyville, Ky., early last year. Even the famous one, the New York blackout, involved UFO sightings. Dr. Hynek probably would be the most appropriate man to describe the Manhattan sighting, since he interviewed several witnesses involved. I interviewed a woman in Seacliff, N.Y. She saw a disk hovering and going up and down. And then shooting away from New York just after the power failure. I went to the FPC for data, they didn’t take them seriously although they had many dozens of sighting reports for that famous evening. There were reports all over new England in the midst of that blackout, and five witnesses near Syracuse, N.Y., saw a glowing object ascending within about a minute of the blackout. First they thought it was a dump burning right at the moment the lights went out. It is rather puzzling that the pulse of current that tripped the relay at the Ontario Hydro Commission plant has never been identified, but initially the tentative suspicion was centered on the Clay Substation of the Niagara Mohawk network right there in the Syracuse area, where unidentified aerial phenomenon has been seen by some of the witnesses.

[[31]]

  This extends down to the limit of single houses losing their power when a UFO is near. The hypothesis in the case of car stopping is that there might be high magnetic fields, d.c. fields, which saturate the core and thus prevent the pulses going through the system to the other side. Just how a UFO could trigger an outage on a large power network is however not yet clear. But this is a disturbing series of coincidences that I think warrant much more attention than they have so far received. Mr. Ryan. As far as you know, has any agency investigated the New York blackout in relation to UFO? Dr. McDonald. None at all. When I spoke to the FPC people, I was dissatisfied with the amount of information I could gain. I am saying there is a puzzling and slightly disturbing coincidence here. I’m not going on record as saying, yes, these are clear-cut cause and effect relations. I’m saying it ought to be looked at. There is no one looking at this relation between UFO’s and outages. Mr. Roush. Our time is really running short, Mr. Ryan. Mr. Ryan. One final question. Do you think it is imperative that the Federal Power Commission, or Federal Communications Commission, investigate the relation if any between the sightings and the blackout? Dr. McDonald. My position would call for a somewhat weaker adjective. I’d say extremely desirable. Mr. Roush. Thank you.   Thank you, Dr. McDonald.

INTRODUCTION

I should like first to commend the House Committee on Science and Astronautics for recognizing the need for a closer look at scientific aspects of the long-standing puzzle of the Unidentified Flying Objects (UFOs). From time to time in the history of science, situations have arisen in which a problem of ultimately enormous importance went begging for adequate attention simply because that problem appeared to involve phenomena so far outside the current bounds of scientific knowledge that it was not even regarded as a legitimate subject of serious scientific concern. That is precisely the situation in which the UFO problem now lies. One of the principal results of my own recent intensive study of the UFO enigma is this: I have become convinced that the scientific community, not only in this country but throughout the world, has been casually ignoring as nonsense a matter of extraordinary scientific importance. The attention of your Committee can, and I hope will, aid greatly in correcting this situation. As you will note in the following, my own present opinion, based on two years of careful study, is that UFOs are probably extraterrestrial devices engaged in something that might very tentatively be termed “surveillance.” If the extraterrestrial hypothesis is proved correct (and I emphasize that the present evidence only points in that direction but cannot be said to constitute irrefutable proof), then clearly UFOs will become a top-priority scientific problem. I believe you might agree that, even if there were a slight chance of the correctness of that hypothesis, the UFOs would demand the most careful attention. In fact, that chance seems to some of us a long way from trivial. We share the view of Vice Adm. R. H. Hillenkoetter, former CIA Director, who said eight years ago, “It is imperative that we learn where the UFOs come from and what their purpose is (Ref. 1)” Since your committee is concerned not only with broad aspects of our national scientific program but also with the prosecution of our entire space program, and since that space program has been tied in for some

[[32]]

years now with the dramatic goal of a search for life in the universe, I submit that the topic of today’s Symposium is eminently deserving of your attention. Indeed, I have to state, for the record, that I believe no other problem within your jurisdiction is of comparable scientific and national importance. Those are strong words, and I intend them to be. In addition to your Committee responsibilities with respect to science and the aerospace programs, there is another still broader basis upon which it is highly appropriate that you now take up the UFO problem: Twenty years of public interest, public puzzlement, and even some public disquiet demand that we all push toward early clarification of this unparalleled scientific mystery. I hope that our session here today will prove a significant turning point, orienting new scientific efforts towards illumination of this scientific problem that has been with us for over 20 years.

SCOPE AND BACKGROUND OF PRESENT COMMENTS

It has been suggested that I review for you my experiences in interviewing UFO witnesses here and abroad and that I discuss ways in which my professional experience in the field of atmospheric physics and meteorology illuminates past and present attempts at accounting for UFO phenomena. To understand the basis of my comments, it may be helpful to note briefly the nature of my own studies on UFOs. I have had a moderate interest in the UFO problem for twenty years, much as have a scattering of other scientists. In southern Arizona, during the period 1956-66, I interviewed, on a generally rather random basis, witness in such local sightings as happened to come to my attention via press or personal communications. This experience taught me much about lay misinterpretations of observations of aircraft, planets, meteors, balloons, flares, and the like. The frequency with which laymen misconstrue phenomena associated with fireballs (meteors brighter than magnitude 5), led me to devote special study to meteor physics; other topics in my own field of atmospheric physics also drew my closer attention as a result of their bearing on various categories of UFO reports. This period of rather casual UFO-witness interviewing on a local basis proved mainly educational; yet on a few occasions I encountered witnesses of seemingly high credibility whose reports lay well outside any evident meteorological, astronomical, or other conventional bounds. Because I was quite unaware, before 1966, that those cases were, in fact, paralleled by astonishing numbers of comparable cases elsewhere in the U.S. and the rest of the world, they left me only moderately puzzled and mildly bothered, since I came upon relatively few impressive cases within the environs of Tucson in those dozen years of discursive study. I was aware of the work of non-official national investigative groups like NICAP (National Investigations Committee on Aerial Phenomena) and APRO (Aerial Phenomena Research Organization) ; but lacking basis for detailed personal evaluation of their investigative methods, I simply did not take their publications very seriously. I was under other misimpressions, I found later, as to the nature of the official UFO program, but I shall not enlarge on this before this Committee. (I cite all of this here because I regard it relevant to an appreciation, by the Committee, of the way in which at least one scientist has developed his present strong concern for the UFO problem, after a prior period of some years of only mild interest.) Despite having interviewed a total of perhaps 150-200 Tucson-area witnesses prior to 1966 (75 of them in a single inconclusive case in 1958), I was far from overwhelmed with the importance of the UFO problem. A particular sighting incident in Tucson in early 1966, followed by the widely-publicized March, 1966, Michigan sightings (I, too, felt that the “swamp gas” explanation was quite absurd once I checked a few relevant points), led me finally to take certain steps to devote the coming summer vacation months to a much closer look at the UFO problem. Within only a few weeks in May and June of 1966, after taking a close look at the files and modes of operation of both private and official (i.e., Project Bluebook) UFO investigative programs, after seeing for the first time press-clipping files of (to me) astonishing bulk, covering innumerable intriguing cases I had never before heard of, and (above all) after the beginning of what became a long period of personal interviewing of key witnesses in important UFO cases, I rapidly altered my conception of the scientific importance of the UFO question. By mid-1966, I had already begun what became months of effort to arouse new interest and to generate new UFO investigative programs in various science agencies of the Federal government

[[33]]

and in various scientific organizations. Now, two years later, with very much more background upon which to base an opinion, I find myself increasingly more concerned with what has happened during the past twenty years’ neglect, by almost the entire scientific community, of a problem that appears to be one of extremely high order of scientific importance.

THE UNCONVENTIONAL NATURE OF THE UFO PROBLEM

To both laymen and scientists, the impressive progress that science has made towards understanding our total environment prompts doubt that there could be machine-like objects of entirely unconventional nature moving through our atmosphere, hovering over automobiles, power installations, cities, and the like, yet all the while going unnoticed by our body scientific. Such suggestions are hard to take seriously, and I assure you that, until I had taken a close look at the evidence. I did not take them seriously. We have managed to so let our preconceptions block serious consideration of the possibility that some form of alien technology is operating within our midst that we have succeeded in simply ignoring the facts. And we scientists have ignored the pleas of groups like NICAP and APRO, who have for years been stressing the remarkable nature of the UFO evidence. Abroad, science has reacted in precisely this same manner, ignoring as nonsensical the report-material gathered by private groups operating outside the main channels of science. I understand this neglect all too well; I was just one more of those scientists who almost ignored those facts, just one more of those scientists who was rather sure that such a situation really could not exist, one more citizen rather sure that official statements must be basically meaningful on the non-existence of any substantial evidence for the reality of UFOs. The UFO problem is so unconventional, involves such improbable events, such inexplicable phenomenology, so defies ready explanation in terms of present-day scientific knowledge, has such a curiously elusive quality in many respects, that it is not surprising (given certain features in the past twenty years’ handling of the problem) that scientists have not taken it very seriously. We scientists are, as a group, not too well-oriented towards taking up problems that lie, not just on the frontiers of our scientific knowledge, but far across some gulf whose very breadth cannot be properly estimated. These parenthetical remarks are made here to convey, in introductory manner, viewpoints that will probably prove to be correct when many more scientists begin to scrutinize this unprecedented and neglected problem. The UFO problem is, if anything, a highly unconventional problem. Hence, before reviewing my own investigations in detail, and before examining various proposed explanations lying within atmospheric physics, it may be well to take note of some of the principal hypotheses that have been proposed. at one time or another, to account for UFOs.

SOME ALTERNATIVE HYPOTHESES

In seeking explanations for UFO reports, I like to weigh witness-accounts in terms of eight principal UFO hypotheses:

  1. Hoaxes, fabrications, and frauds.
  2. Hallucination, mass hysteria, rumor phenomena.
  3. Lay misinterpretations of well-know physical phenomena (meteorological, astronomical, optical, aeronautical, etc.).
  4. Semi-secret advanced technology (new test vehicles, satellites, novel weapons, flares, re-entry phenomena, etc.).
  5. Poorly understood physical phenomena (rare atmospheric-electrical or atmospheric-electrical effects, unusual meteoric phenomena, natural or artificial plasmoids, etc.).
  6. Poorly understood psychological phenomena.
  7. Extraterrestrial devices of some surveillance nature.
  8. Spaceships bringing messengers of terrestrial salvation and occult truth.

Because I have discussed elsewhere all of these hypotheses in some detail (Ref. 2), I shall here only very briefly comment on certain points. Hoaxes and fabrications do crop up, though in percentually [sic] far smaller numbers than many UFO scoffers seem to think. Some of the independent groups like APRO and NICAP have done good work in exposing certain of these. Although there has been a good deal of armchair-psychologizing about unstable UFO witnesses, with easy charges of hallucination and hysteria, such charges seem to have almost no

[[34]]

bearing in the hundreds of cases I have now personally investigated. Misinterpreted natural phenomena (Hypothesis 3) do explain many sincerely-submitted UFO reports; but, as I shall elaborate below, efforts to explain away almost the entirety of all UFO incidents in such terms have been based on quite unacceptable reasoning. Almost no one any longer seriously proposes that the truly puzzling UFO reports of close-range sighting of what appear to be machines of some sort are chance sightings of secret test devices (ours or theirs) ; the reasons weighing against Hypothesis 4 are both obvious and numerous. That some still-not-understood physical phenomena of perhaps astronomical or meteorological nature can account for the UFO observations that have prompted some to speak in terms of extraterrestrial devices would hold some weight if it were true that we dealt therein only with reports of hazy, glowing masses comparable to, say, ball lightning or if we dealt only with fast-moving luminous bodies racing across the sky in meteoric fashion. Not so, as I shall enlarge upon below. Jumping to Hypothesis 6, it seems to receive little support from the many psychologists with whom I have managed to have discussions on this possibility; I do not omit it from consideration, but, as my own witness-interviewing has proceeded, I regard it with decreasing favor. As for Hypothesis 8, it can only be remarked that, in all of the extensive literature published in support thereof, practically none of it has enough ring of authenticity to warrant serious attention. A bizarre “literature” of pseudo-scientific discussion of communications between benign extraterrestrials bent on saving the better elements of humanity from some dire fate implicit in nuclear-weapons testing or other forms of environmental contamination is certainly obtrusive on any paperback stand. That “literature” has been one of the prime factors in discouraging serious scientists from looking into the UFO matter to the extent that might have led them to recognize quickly enough that cultism and wishful thinking have essentially nothing to do with the core of the UFO problem. Again, one must here criticize a good deal of armchair researching (done chiefly via the daily newspapers that enjoy feature-writing the antics of the more extreme of such groups). A disturbing number of prominent scientists have jumped all too easily, to the conclusion that only the nuts see UFOs. The seventh hypothesis, that UFOs may be some form of extraterrestrial devices, origin and objective still unknown, is a hypothesis that has been seriously proposed by many investigators of the UFO problem. Although there seems to be some evidence that this hypothesis was first seriously considered within official investigative channels in 1948 (a year after the June 24,1947 sighting over Mt. Rainier that brought the UFO problem before the general public), the first open defense of that Hypothesis 7 to be based on any substantial volume of evidence was made by Keyhoe (Ref. 3) in about 1950. His subsequent writings, based on far more evidence than was available to him in 1950, have presented further arguments favoring an extraterrestrial origin of UFOs. Before I began an intensive examination of the UFO problem in 1966, I was disposed to strong doubt that the numerous cases discussed at length in Keyhoe’s rather dramatically-written and dramatically-titled books (Ref. 4) could be real cases from real witnesses of any appreciable credibility. I had the same reaction to a 1956 book (Ref. 5) written by Ruppelt, an engineer in charge of the official investigations in the important 1951-3 period. Ruppelt did not go as far as Keyhoe in suggesting the extraterrestrial UFO hypothesis, but he left his readers little room for doubt that he leaned toward that hypothesis. I elaborate these two writers’ viewpoints because, within the past month, I have had an opportunity to examine in detail a large amount of formerly classified official file material which substantiates to an almost alarming degree the authenticity and hence the scientific import of the case-material upon which Keyhoe and Ruppelt drew for much of their discussions of UFO history in the 1947-53 period (Refs. 6 and 7). One of these sources has just been published by NICAP (Ref. 7), and constitutes, in my opinion, an exceedingly valuable addition to the growing UFO literature. The defense of the extraterrestrial hypothesis by Keyhoe, and later many others (still not within what are conventionally regarded as scientific circles), has had little impact on the scientific community, which based its write-off of the UFO problem on press accounts and official assurances that careful investigations were turning up nothing that suggested phenomena beyond present scientific explanation. Hypothesis No. 7 has thus received short shrift from science to date. As one scientist who has gone to some effort to try to examine the facts, I say that this has been an egregious, if basically unwitting, scientific error — an error that must be rectified with minimum further delay. On the basis of the evidence I

[[35]]

have examined, and on the basis of my own weighing of alternative hypotheses (including some not listed above), I now regard Hypothesis 7 as the one most likely to prove correct. My scientific instincts lead me to hedge that prediction just to the extent of suggesting that if the UFOs are not of extramundane origin, then I suspect that they will prove to be something very much more bizarre, something of perhaps even greater scientific interest than extraterrestrial devices.

SOME REMARKS ON INTERVIEWING EXPERIENCE AND TYPES OF UFO CASES ENCOUNTERED

1. Sources of cases dealt with Prior to 1966, I had interviewed about 150-200 persons reporting UFOs; since 1966, I have interviewed about 200-250 more. The basis of my post-1966 interviewing has been quite different from the earlier period of interviewing of local witnesses, whose sightings I heard about essentially by chance. Almost all of my post-1966 interviews have been with witnesses in cases already investigated by one or more of the private UFO investigatory groups such as NICAP or APRO, or by the official investigative agency (Project Bluebook). Thus, after 1966, I was not dealing with a body of witnesses reporting Venus, fireballs, and aircraft strobe lights, because such cases are so easily recognizable that the groups whose prior checks I was taking advantage of had already culled out and rejected most of such irrelevant material. Many of the cases I checked were older cases, some over 20 years old. It was primarily the background work of the many independent investigatory groups here and in other parts of the world (especially the Australian area where I had an opportunity to interview about 80 witnesses) that made possible my dealing with that type of once-sifted data that yields up scientifically interesting information so quickly. I wish to put on record my indebtedness to these “dedicated amateurs”, to use the astronomer’s genial term; their contribution to the ultimate clarification of the UFO problem will become recognized as having been of basic importance, notwithstanding the scorn with which scientists have, on more than one occasion, dismissed their efforts. Although I cite only the larger of these groups (NICAP about 12,000 members, APRO about 8,000), there are many smaller groups here and abroad that have done a most commendable job on almost no resources. (Needless to add, there are other small groups whose concern is only with sensational and speculative aspects.) 2. Some relevant witness-characteristics By frequently discussing my own interviewing experience with members of those non-official UFO groups whose past work has been so indispensable to my own studies, I have learned that most of my own reactions to the UFO witness-interview problem are shared by those investigators. The recurrent problem of securing unequivocal descriptions, the almost excruciating difficulty in securing meaningful estimates of angular size, angular elevation, and angular displacements from laymen, the inevitable variance of witness-descriptions of a shared observation, and other difficulties of non-instrumental observing are familiar to all who have investigated UFO reports. But so also are the impressions of widespread concern among UFO witnesses to avoid (rather than to seek) publicity over their sightings. The strong disinclination to make an open report of an observation of something the witness realizes is far outside the bounds of accepted experience crops up again and again. In my interviewing in 1947 sightings, done as a crosscheck on case material used in a very valuable recent publication by Bloecher (Ref. 8), I came to realize clearly for the first time that this reluctance was not something instilled by post-1947 scoffing at UFOs, but is part of a broadly disseminated attitude to discount the anomalous and the inexplicable, to be unwilling even to report what one has seen with his own eyes if it is well outside normal experience as currently accepted. I have heard fellow-scientists express dismay at the unscientific credulity with which the general public jumps to the conclusion that UFOs are spaceships. Those scientists have certainly not interviewed many UFO witnesses; for almost precisely the opposite attitude is overwhelmingly the characteristic response. In my Australian interviewing, I found the same uneasy feeling about openly reporting an observation of a well-defined UFO sighting, lest acquaintances think one “has gone round the bend.” Investigators in still other parts of the world where modern scientific values dominate world-views have told me of encountering just this same witness-reluctance. The charge that UFO witnesses, as a group, are hyperexcitable types is entirely incorrect I would agree with the way Maj. Gen. John A. Samford, then Director of

[[36]]

Air Force Intelligence, put it in a 1952 Pentagon press conference: “Credible observers have sighted relatively incredible objects.” Not only is the charge of notoriety-seeking wrong, not only is the charge of hyperexcitability quite inappropriate to the witnesses I have interviewed, but so also is the easy charge that they see an unusual aerial phenomenon and directly leap to some kind of “spaceship hypothesis.” My experience in interviewing witnesses in the selected sample I have examined since 1966 is that the witness first attempts to fit the anomalous observation into some entirely conventional category. “I thought it must be an airplane.” Or, “At first, I thought it was an auto-wrecker with its red light blinking.” Or, “I thought it was a meteor — until it stopped dead in midair,” etc. Hynek has a very happy phrase for this very typical pattern of witness-response: he terms it “escalation of explanation”, to denote the often rapid succession of increasingly more involved attempts to account for and to assimilate what is passing before the witness’ eyes, almost invariably starting with an everyday interpretation, not with a spaceship hypothesis. Indeed, I probably react in a way characteristic of all UFO investigators; in those comparatively rare cases where the witness discloses that he immediately interpreted what he sighted as an extraterrestrial device, I back away from what is likely to be a most unprofitable interview. I repeat: such instances are really quite rare; most of the general population has soaked up a degree of scientific conventionalism that reflects the net result of decades, if not centuries of scientific shaping of our views. I might interject that the segment of the population drawn to Hypothesis 8 above might be quick to jump to a spaceship interpretation on seeing something unusual in the sky, but, on the whole, those persons convinced of Hypothesis 8 are quite uninterested in observations, per se. Their conviction is firm without bothering about such things as observational matters. At least that is what I have sensed from such exposure as I have had to those who support Hypothesis 8 fervently. 3. Credibility of witnesses Evaluating credibility of witnesses is, of course, an ever-present problem at the present stage of UFO studies. Again, from discussions with other investigators, I have concluded that common sense and previous everyday experience with prevaricators and unreliable persons lead. each serious UFO investigator to evolve a set of criteria that do not differ much from those used in jury instructions in our courts (e.g. Federal Jury Instructions). It seems tedious to enlarge here on those obvious matters. One can be fooled, of course; but it would be rash indeed to suggest that the thousands of UFO reports now on record are simply a testimony to confabulation, as will be better argued by some of the cases to be recounted below. 4. Observational reliability of witnesses Separate from credibility in the sense of trustworthiness and honesty is the question of the human being as a sensing system. Clearly, it is indispensable to be aware of psychophysical factors limiting visual discrimination, time estimation, distance estimation, angular estimation, etc. In dealing with the total sample of all observations which laymen initially label as UFOs, such factors play a large role in sorting out dubious cases. In the type of UFO reports that are of primary significance at present, close-range sightings of objects of large size moving at low velocities, or at rest, and in sight for many seconds rather than fractions of a second, all of these perceptual problems diminish in significance, though they can never be overlooked. A frequent objection to serious consideration of UFO reports, made by skeptics who have done no first-hand case investigations, is based on the widely discrepant accounts known to be presented by trial-witnesses who have all been present at some incident. To be sure, the same kind of discrepancies emerge in multiple-witness UFO incidents. People differ as to directions, relative times, sizes, etc. But I believe it is not unfair to remark, as the basic rebuttal to this attack on UFO accounts, that a group of witnesses who see a street-corner automobile collision do not come to court and proceed, in turn, to describe the event as a rhinoceros ramming a baby carriage, or as an airplane exploding on impact with a nearby building. There are, it needs to be soberly remembered, quite reasonable bounds upon the variance of witness testimonies in such cases. Thus, when one finds a half-dozen persons all saying that they were a few hundred feet from a domed disk with no resemblance to any known aircraft, that it took off without a sound, and was gone from sight in five seconds, the almost inevitable variations in descriptions of distances, shape, secondary features, noises, and times

[[37]]

cannot be allowed to discount, per se, the basically significant nature of their collective account. I have talked with a few scientists, especially some psychologists, whose puristic insistence on the miserable observing equipment with which the human species is cursed almost makes me wonder how they dare cross a busy traffic intersection. Some balance in evaluating witness perceptual limitations is surely called for in all of these situations. With that balance must go a healthy skepticism as to most of the finer details, unless agreed upon by several independent witnesses. There is no blinking that anecdotal data are less than ideal; but sometimes you have to go with what you’ve got. To make a beginning at UFO study has required scrutiny of such anecdotal data; the urgent need is to get on to something much better. 5. Problem of witness’ prior knowledge of UFO phenomena In interviewing UFO witnesses, it is important to try to ascertain whether the witness was, prior to his reported sighting, familiar or unfamiliar with books and writings on UFOs. Although a strong degree of familiarity with the literature of UFOs does not negate witness testimony, it dictates caution. Anyone who has done a lot of interviewing at the local level, involving previously unsifted cases, will be familiar with occasional instances where the witness exhibited such an obvious enthusiasm for the UFO problem that prudence demanded rejection of his account. However, in my own experience, a much more common reaction to questions concerning pre-sighting interest in UFO matters is some comment to the effect that the witness not only knew little about UFOs beyond what he’d happened to read in newspapers, but he was strongly disinclined to take the whole business seriously. The repetitiveness and yet the spontaneity with which witnesses of seeming high credibility make statements similar to, “I didn’t believe there was anything to all the talk about UFOs until I actually saw this thing,” is a notable feature of the interview-experience of all of the investigators with whom I have talked. Obviously, an intending prevaricator might seek to deceive his interrogator by inventing such an assertion ; but I can only say that suspicion of being so duped has not been aroused more than once or twice in all of the hundreds of witnesses I have interviewed. On the other hand, I suppose that. In several dozen instances, I have lost interest in a case because of a witness openly stressing his own prior and subsequent interest in the extraterrestrial hypothesis. Occasionally one encounters witnesses for whom the chance of prior knowledge is so low as to be almost amusing. An Anglican missionary in New Guinea, Rev. N. E. G. Cruttwell (Ref. 9), who has done much interviewing of UFO witnesses in his area, has described testimony of natives who come down into the mission area from their highland home territory only when they are wallaby-hunting, natives who could not read UFO reports in any language of the world, yet who come around, in their descriptions of what they have seen, to the communications-shortcut of picking up a bowl or dish from a nearby table to suggest the shape they are seeking to describe in native tongue. Little chance of bias gained from reading magazines in a barber-chair in such instances. 6. Types of UFO accounts of present interest The scope of the present statement precludes anything approaching an exhaustive listing of categories of UFO phenomena: much of what might be made clear at great length will have to be compressed into my remark that the scientific world at large is in for a shock when it becomes aware of the astonishing nature of the UFO phenomenon and its bewildering complexity. I make that terse comment well aware that it invites easy ridicule; but intellectual honesty demands that I make clear that my two years’ study convinces me that in the UFO problem lie scientific and technological questions that will challenge the ability of the world’s outstanding scientists to explain as soon as they start examining the facts. (a) Lights in the night sky. — (“DLs” As they are called by the NICAP staff, on the basis that the profusion of reports of “damnable lights” meandering or hovering or racing across the night sky in unexplainable manner are one of the most common, yet one of the least useful and significant categories of UFO reports.) Ultimately, I think their significance could become scientifically very substantial when instrumental observing techniques are in wide use to monitor UFO movements. But there are many ways that observers can be misled by lights in the night sky, so I shall discuss below only such few cases as are of extremely unconventional nature and where the protocols of the observations are unusually strong.

[[38]]

 (b) Close-range sighting’s of wingless discs and cigar-shaped objects. — This category is far more interesting. Many are daytime sightings, many have been made by witnesses of quite high credibility. Structural details such as “ports” and “legs” (to use the terms the witnesses have adopted to suggest most closely what they think they have seen) are described in many instances. Lack of wings and lack of evident means of propulsion clearly rule out conventional aircraft and helicopters. Many are soundless, many move at such speeds and with such accelerations that they defy understanding in terms of present technology. It is to be understood that I speak here only of reports from what I regard as credible observers. (c) Close-range nighttime sightings of glowing, hovering objects, often with blinking or pulsating discrete lights. — In these instances, distinct shape is not seen, evidently in many cases because of the brilliance of the lights. Less significant than those of the preceding category, these nonetheless cannot be accounted for in terms of any known vehicles. Frequently they are reported hovering over vehicles on the ground or following them. Sometimes they are reported hovering over structures, factories, power installations, and the like. Soundlessness is typical. Estimated sizes vary widely, over a range that I do not believe can be accounted for simply in terms of the known unreliability of distance and size estimates when one views an unknown object. (d) Radar-tracked objects, sometimes seen visually simultaneously by observers on the ground or in the air. — In many of these cases, the clues to the non-conventional nature of the radar target is high speed (estimated at thousands of miles per hour in certain instances); in others, it is alternate motion and hovering; in still others, it has been the unconventional vertical motions that make the radar observations significant. Clearly, most important are those instances in which there was close agreement between the visual and the radar unknown. There are far more such cases than either scientists or public would guess. Those four categories do not exhaust the list by any means. But they constitute four commonly encountered categories that are of interest here. Examples will be found below. 7. Commonly encountered questions As Mark Twain said, “Faith is a great thing, but it’s doubt that gets you an education.” There are many questions that one encounters again and again from persons who have done no personal case-checking and who maintain a healthy skepticism about UFOs. Why don’t pilots report these things if they are buzzing around in our skies? Why aren’t they tracked on radar? Why don’t our satellite and astronomical tracking systems get photos of UFOs? Why are they always seen in out-of-the way rural areas but never over large cities? Why don’t large groups of people ever simultaneously see UFOs, instead of lone individuals? Why don’t astronomers see them? Shouldn’t UFOs occasionally crash and leave clear-cut physical evidence of their reality? Or shouldn’t they at least leave some residual physical evidence in those alleged instances where the objects have landed? Shouldn’t they affect radios and produce other electromagnetic effects at times? If UFOs are a product of some high civilization, wouldn’t one expect something of the nature of inquisitive behavior, since innate curiosity must be a common denominator of anything we would call “Intelligence”? Why haven’t they contacted us if they’re from somewhere else in the universe and have been here for at least two decades? Is there any evidence of hostility or hazard? Are UFOs seen only in this country? Why didn’t we see them before 1947, if they come from remote sources? And so on. In the following sections, I shall show how some of these questions do have quite satisfactory answers, and how some of them still defy adequate rebuttal. I shall use mostly cases that I have personally investigated, but, in a few instances (clearly indicated), I shall draw upon cases which I have not directly checked but for which I regard the case-credentials as very strong. 8. Useful source materials on UFO’s Hoping that Committee staff personnel will be pursuing these matters further, I remark next on some of the more significant items in the UFO literature. All of these have been helpful in my own studies. One of the outstanding UFO references (though little-known in scientific circles) is The UFO Evidence, edited by R. H. Hall and published by NICAP (Ref. 10). It summarizes about 750 UFO cases in the NICAP flies up to about

[[39]]

1964. I have cross-checked a sufficiently large sample of cases from this reference to have confidence in its generally very high reliability. A sequel volume, now in editorial preparation at NICAP, will cover the 1964-68 period. Reference 8, by Bloecher, is one of the few sources of extensive documentation (here primarily from national newspaper sources) of the large cluster of sightings in a period of just a few weeks in the summer of 1947; its study is essential to appreciation of the opening phases of the publicly recognized UFO problem. Reference 7 is another now-accessible source of extremely significant UFO documentation; it is unfortunate that no generally accessible version of Reference 6 exists, though the Moss Subcommittee, through pleas of Dr. Leon Davidson, has managed to get it into a status of at least limited accessibility. I am indebted to Davidson for a recent opportunity to study it for details I missed when I saw it two years ago at Bluebook headquarters. The 1956 book by Ruppelt (Ref. 8) is a source whose authenticity I have learned, through much personal cross-checking, is far higher than I surmised when I first read it a dozen years ago. It was for years difficult for me to believe that the case-material which he summarized could come from real cases. References 5 and 6, plus other sources, do, however, now attest to Ruppelt’s generally high reliability. Similarly Keyhoe’s books (Refs. 3 and 4) emerge as sources of UFO case material whose reliability far exceeds my own first estimates thereof. As a scientist, I would have been much more comfortable about Keyhoe’s books had they been shorn of extensive direct quotes and suspenseful dramatizations; but I must stress that much checking on my part has convinced me that Keyhoe’s reportorial accuracy was almost uniformly high. Scientists will tend to be put off by some of his scientific commentary, as well as by his style; but on UFO case material, his reliability must be recognized as impressive. (Perhaps it is well to insert here the general proviso that none of these sources, including myself, can be expected to be characterized by 100 per cent accuracy in a problem as intrinsically messy as the UFO problem; here I am trying to draw attention to sources whose reliability appears to be in the 90+% range.) A useful collection of 160 UFO cases drawn from a wide variety of sources has been published by Olsen (Ref. 11), 32 of which he obtained directly from the official files of Project Bluebook, a feature of particular interest. A book devoted to a single short period of numerous UFO observations within a small geographic area, centering around an important sighting near Exeter, N.H., is Fuller’s Incident at Exeter (Ref. 12). Having checked personally on a number of features of the main Sept. 3, 1965, sighting, and having checked indirectly on other aspects, I would describe Reference 12 as one of the significant source-items on UFOs. Several books by the Lorenzens, organizers of APRO, the oldest continuing UFO investigating group in this country, contain valuable UFO reference material (Ref. 13). Through their writing, and especially through the APRO Bulletin, they have transmitted from South American sources numerous unusual sightings from that country. I have had almost no opportunity to cross-check those sightings, but am satisfied that some quite reliable sources are being drawn upon. An extremely unusual category of cases, those involving reports of humanoid occupants of landed UFOs, has been explored to a greater extent by APRO than by NICAP. Like NICAP, I have tended to skirt such cases on tactical grounds; the reports are bizarre, and the circumstances of all such sightings are automatically charged in a psychological sense not found in other types of close-range sightings of mere machine-like devices. Since I shall not take up below this occupant problem, let me add the comment that I do regard the total number of such seemingly reliable reports (well over a hundred came just from central France in the outstanding 1954 sighting wave in that country), far too great to brush aside. Expert psychological opinion is badly needed in assessing such reports (expert but not close-minded opinion). For the record, I should have to state that my interviewing results dispose me toward acceptance of the existence of humanoid occupants in some UFOs. I would not argue with those who say that this might be the single most important element of the entire UFO puzzle; I would only say that most of my efforts over the past two years, being aimed at arousing a new degree of scientific interest among my colleagues in the physical sciences, have led me to play down even the little that I do know about occupant sightings. One or two early attempts to touch upon that point within the time-limits of a one-hour colloquium taught me that one loses more than he gains in speaking briefly about UFO occupants. (Occupant sightings must be carefully distinguished from elaborate “contact-claims” with the Space Brothers;

[[40]]

I hold no brief at all for the latter in terms of my present knowledge and interviewing experience. But occupants there seem to be, and contact of a limited sort may well have occurred, according to certain of the reports. I do not regard myself as very well-informed on this point, and will say little more on this below.) It is, of course, somewhat more difficult to assess the reliability of foreign UFO references. Michel (Ref. 13) has assembled a day-by-day account of the remarkable French UFO wave of the fall of 1954, translated into English by the staff of CSI (Civilian Saucer Intelligence) of New York City, a now-inactive but once very productive independent group. I have spoken with persons having first-hand knowledge of the French 1954 episode, and they attest to its astonishing nature. Life and The New Yorker published full contemporary accounts at the time of the 1954 European wave. An earlier book by Michel (Ref. 14), also available in English, deals with a broader temporal and geographic range of European UFO sightings. A just-published account of about 70 UFO sightings that occurred within a relatively small area around Stoke-on-Trent, England, in the summer and fall of 1967 (Ref. 15) presents an unusual cross-section of sightings that appear to be well-documented. A number of foreign UFO journals are helpful sources of the steady flow of UFO reports from other parts of the world, but a cataloging will not be attempted here. Information on some of these, as well as on smaller American groups, can be found in the two important books by Vallee (Refs. 16 and 17). Information on pre-1947 UFO-type sightings form the subject of a recent study by Lore and Denault (Ref. 18). I shall return to this phase of the UFO problem below; I regard it as being of potentially very great significance, though there is need for far more scholarly and scientific research before much of it can be safely interpreted. Another source of sightings of which many may ultimately be found to fall within the presently understood category of UFO sightings is the writings of Charles Fort (Ref. 19). His curious books are often drawn upon for material on old sightings, but not often duly acknowledged for the mine of information they comprise. I am afraid that it has not been fashionable to take Fort seriously; it certainly took me some time to recognize that, mixed into his voluminous writings, is much that remains untapped for its scientific import. I cannot imagine any escalated program of research on the UFO program that would not have a subgroup studying Fortean reports documented from 19th century sources. To close this brief compilation of useful UFO references, two recent commentaries (not primarily source-references) of merit may be cited, books by Stanton (Ref. 20) and by Young (Ref. 21). Next, I examine a number of specific UFO cases that shed light on many of the recurrent questions of skeptical slant often raised against serious consideration of the UFO problem.

WHY DON’T PILOTS SEE UFO’S?

This question may come in just that form from persons with essentially no knowledge of UFO history. From others who do know that there have been “a few” pilot-sightings, it comes in some altered form, such as, “Why don’t airline and military pilots see UFO’s all the time if they are in our atmosphere?” By way of partial answer, consider the following cases. (To facilitate internal reference, I shall number sequentially all cases hereafter treated in detail.) 1. Case 1. Boise, Idaho, July 4, 1947 Only about a week after the now-famous Mt. Rainier sighting by private pilot Kenneth Arnold, a United Air Lines DC-3 crew sighted two separate formations of wingless discs, shortly after takeoff from Boise (Refs. 8, 10, 22, 28). I located and interviewed the pilot, Capt. Emil J. Smith, now with United’s New York office. He confirmed the reliability of previously published accounts. United Flight 105 had left Boise at 9:04 p.m. About eight minutes out, en route to Seattle, roughly over Emmet, Idaho, Co-pilot Stevens, who spotted the first of two groups of objects, turned on his landing lights under the initial impression the objects were aircraft. But, studying them against the twilight sky, Smith and Stevens soon realized that neither wings nor tails were visible on the five objects ahead. After calling a stewardess, in order to get a third confirming witness, they watched the formation a bit longer, called Ontario, Oregon CAA to try to get ground-confirmation, and then saw the formation spurt ahead and disappear at high speed off to the west.

[[41]]

Smith emphasized to me that there were no cloud phenomena to confuse them here and that they observed these objects long enough to be quite certain that they were no conventional aircraft. They appeared “flat on the bottom, rounded on top”, he told me, and he added that there seemed to be perceptible “roughness” of some sort on top, though he could not refine that description. Almost immediately after they lost sight of the first five, a second formation of four (three in line and a fourth off to the side) moved in ahead of their position, again traveling westward but at a somewhat higher altitude than the DC-3’s 8000 ft. These passed quickly out of sight to the west at speeds which they felt were far beyond then-known speeds. Smith emphasized that they were never certain of sizes and distances, but that they had the general impression that these disc-like craft were appreciably larger than ordinary aircraft. Smith emphasized that he had not taken seriously the previous week’s news accounts that coined the since-persistent term, “flying saucer.” But, after seeing this total of nine unconventional, high-speed wingless craft on the evening of 7/4/47, he became much more interested in the matter. Nevertheless, in talking with me, he stressed that he would not speculate on their real nature or origin. I have spoken with United Air Lines personnel who have known Smith for years and vouch for his complete reliability. Discussion. — The 7/4/47 United Air Lines sighting is of historic interest because it was obviously given much more credence than any of the other 85 UFO reports published in press accounts on July 4, 1947 (see Ref. 8). By no means the most impressive UFO sighting by an airliner crew, nevertheless, it is a significant one. It occurred in clear weather, spanned a total time estimated at 10-12 minutes, was a multiple-witness case including two experienced observers familiar with airborne devices, and was made over a 1000-ft. altitude range (climb-out) that, taken together with the fact that the nine objects were seen well above the horizon, entirely rules out optical phenomena as a ready explanation. It is officially listed as a Unidentified. 2. Case 2. Montgomery, Alabama, July 24, 1948 Another one of the famous airline sightings of earlier years is the Chiles-Whitted Eastern Airlines case (Refs. 3, 5, 6 , 10, 23, 24, 25, 26). An Eastern DC-3, en route from Houston to Atlanta, was flying at an altitude of about 5000 ft., near Montgomery at 2:45 a.m. The pilot, Capt. Clarence S. Chiles, and the co-pilot, John B. Whitted, both of whom now fly jets for Eastern, were experienced fliers (for example, Chiles then had 8500 hours in the air, and both had wartime military flying duty behind them). I interviewed both Chiles and Whitted earlier this year to cross-check the many points of interests in this case. Space precludes a full account of all relevant details. Chiles pointed out to me that they first saw the object coming out of a distant squall-line area which they were just reconnoitering. At first, they thought it was a jet, whose exhaust was somehow accounting for the advancing glow that had first caught their eyes. Coming almost directly at them at nearly their flight altitude, it passed off their starboard wing at a distance on which the two men could not closely agree: one felt it was under 1000 ft, the other put it at several times that. But both agreed, then and in my 1968 interview, that the object was some kind of vehicle. They saw no wings or empennage, but both were struck by a pair of rows of windows or some apparent openings from which there came a bright glow “like burning magnesium.” The object had a pointed “nose”, and from the nose to the rear along its underside there was a bluish glow. Out of the rear end came an orange-red exhaust or wake that extended back by about the same distance as the object’s length. The two men agreed that its size approximated that of a B-29, though perhaps twice as thick. Their uncertainty as to true distance, of course, renders this only a rough impression. There is uncertainty in the record, and in their respective recollections, as to whether their DC-3 was rocked by something like a wake. Perception of such an effect would have been masked by Chiles’ spontaneous reaction of turning the DC-3 off to the left as the object came in on their right Both saw it pass aft of them and do an abrupt pull-up, but only Whitted, on the right side, saw the terminal phase in which the object disappeared after a short but fast vertical ascent By “disappeared”, Whitted made clear to me that he meant just that; earlier interrogations evidently construed this to mean “disappeared aloft” or into the broken cloud deck that lay above them. Whitted said that was not so; the object vanished instantaneously after its sharp pull-up. (This is not an isolated instance of abrupt disappearance. Obviously I cannot account for such cases.)

[[42]]

Discussion. — This case has been the subject of much comment over the years, and rightly so. Menzel (Ref. 24) first .proposed that this was a “mirage”, but gave no basis for such an unreasonable interpretation. The large azimuth-change of the pilots’ line of sight, the lack of any obvious light source to provide a basis for the rather detailed structure of what was seen, the sharp pull-up, and the high flight altitude involved all argue quite strongly against such a casual disposition of the case. In his second book, Menzel (Ref. 25) shifts to the explanation that they had obviously seen a meteor. A horizontally-moving fireball under a cloud-deck, at 5000 ft., exhibiting two rows of lights construed by experienced pilots as ports, and finally executing a most non-ballistic 90-degree sharp pull-up, is a strange fireball indeed. Menzel’s 1963 explanation is even more objectionable, in that he implies, via a page of side-discussion, that the Eastern pilots had seen a fireball from the Delta Aquarid meteor stream. As I have pointed out elsewhere (Ref. 2), the radiant of that stream was well over 90 away from the origin point of the unknown object. Also, bright fireballs are, with only rare exceptions, not typical of meteor streams. The official explanation was shifted recently from “Unidentified” to “Meteor”, following publication of Menzel’s 1963 discussion (see Ref. 20, p. 88). Wingless, cigar-shaped or “rocket-shaped” objects, some emitting glowing wakes, have been reported by other witnesses. Thus, Air Force Capt. Jack Puckett, flying near 4000 ft. over Tampa in a C-47 on August 1, 1946 (Ref. 10, p. 23), described seeing “a long, cylindrical shape approximately twice the size of a B-29 with luminous portholes”, from the aft end of which there came a stream of fire as it flew near his aircraft. Puckett states that he, his copilot, Lt. H. F. Glass, and the flight engineer also saw it as it came into within an estimated 1000 yards before veering off. Another somewhat similar airborne sighting, made on January 22, 1956 by TWA Flight Engineer Robert Mueller at night over New Orleans, is on record (Ref. 27). Still another similar sighting is the AAL case cited below (Sperry case). Again, over Truk Is., in the Pacific, a Feb. 6, 1953, mid-day sighting by a weather officer involved a bullet-shaped object without wings or tail (Ref. 7, Rept. No. 10). Finally, within an hour’s time of the Chiles-Whitted sighting. Air Force ground personnel at Robins AFB, Georgia, saw a rocket-like object shoot overhead in a westerly direction (Refs. 3, 5, 10, 6). In none of these instances does a meteorological or astronomical explanation suffice to explain the sightings. 3. Case 3. Sioux City, Iowa, January 20, 1951. Another of the many airline-crew sightings of highly unconventional aerial devices that I have personally checked was, like Cases 1 and 2, widely reported in the national press (for a day or two, and then forgotten like the rest). A check of weather data confirms that the night of 1/20/51 was clear and cold at Sioux City at the time that a Mid-Continent Airlines DC-3, piloted by Lawrence W. Vinther, was about to take off for Omaha and Kansas City, at 8:20 p.m. CST. In the CAA control tower, John M. Williams had been noting an oddly manenvering light high in a westerly direction. Suddently the light abruptly accelerated, in a manner clearly precluding either meteoric or aircraft origin, so Williams alerted Vinther and his co-pilot, James F. Bachmeier. The incident has been discussed many times (Ref. 4,5, 10, and 28), but to check details of these reports, I searched for and finally located all three of the above-named men. Vinther and Bachmeier are now Braniff pilots, Williams is with the FAA in Sacramento. From them I confirmed the principal features of previous accounts and learned additional information too lengthy to recapitulate in full here. The essential point to be emphasized is that, shortly after Vinther got his DC-3 airborne, under Williams’ instructions to investigate the oddly-behaving light, the object executed a sudden dive and flew over the DC-3 at an estimated 200 ft. vertical clearance, passing aft and downward. Then a surprising maneuver unfolded. As Vinther described it to me, and as described in contemporary accounts, the object suddenly reversed course almost 180°, without slowing down or slewing, and was momentarily flying formation with their DC-3, off its port wing. (Vinther’s dry comment to me was: “This is something we don’t see airplanes do.”) Vinther and Bachmeier agreed that the object was very big, perhaps somewhat larger than a B-29, they suggested to newspapermen who interviewed them the following day. Moonlight gave them a good silhouetted view of the object, which they described as having the form of a fuselage and unswept wing, but not a sign of any empennage, nor any sign of engine-pods, propellers, or jets. Prior to its dive, it had been seen only as a light; while pacing their DC-3, the men saw no luminosity, though during the dive they saw a light on its underside. After about five seconds, the unknown object

[[43]]

began to descend below them and flew under their plane. They put the DC-3 into a steep bank to try to keep it in view as it began this maneuver; and as it crossed under them, they lost it, not to regain sight of it subsequently. There is much more detail, not all mutually consistent as to maneuvers and directions, in the full accounts I obtained from Vinther, Bachmeier, and Williams. The dive, pacing, and fly-under maneuvers were made quickly and at such a distance from the field that Williams did not see them clearly, though he did see the object leave the vicinity of the DC-3. An Air Force colonel and his aide were among the passengers, and the aide caught a glimpse of the unknown object, but I have been unable to locate him for further cross-check. Discussion. — The erratic maneuvers exhibited by the unknown object while under observation from the control tower would, by themselves, make this a better-than-average case. But the fact that those maneuvers prompted a tower operator to alert a departing aircrew to investigate, only to have the object dive upon and pace the aircraft after a non-inertial course-reversal, makes this an unusually interesting UFO. Its configuration, about which Vinther and Bachmeier were quite positive in their remarks to me (they repeatedly emphasized the bright moonlight, which checks with the near-full moon on 1/20/51 and the sky-cover data I obtained from the Sioux City Weather Bureau), combines with other features of the sighting to make it a most significant case. The reported shape (tailless, engineless, unswept aircraft of large size) does not match that of any other UFO that I am aware of; but my exposure to the bewildering range of reported configurations now on record makes this point less difficult to assimilate. This case is officially carried as Unidentified, and, in a 1958 publication (Ref. 29), was one of 12 Unidentifieds singled out for special comment. A contemporary account (Ref. 28), taking note of a then recent pronouncement that virtually all UFOs are explainable in terms of misidentified Skyhook balloons, carried a lead-caption. “The Office of Naval Research claims that cosmic ray balloons explain all saucer reports. If so, what did this pilot see?” Certainly it would not be readily explained away as a balloon, a meteor, a sundog, or ball lighting. Rather, it seems to be just one more of thousands of Unidentified Flying Objects for which we have no present explanations because we have laughed such reports out of scientific court. Bachmeier stated to me that, at the time, he felt it had to be some kind of secret device, but, in the ensuing 17 years, we have not heard of any aircraft that can execute instantaneous course-reversal. Vinther’s comment to me on a final question I asked as to what he thinks, in general, about the many airline-pilot sightings of unidentified objects over the past 20 years, was: “We’re not all having hallucinations.” 4. Case 4. Minneapolis, Minn., October 11, 1951 There are far more private pilots than airline pilots, so it is not surprising that there are more UFO sightings from the former than the latter. An engineer and former Air Force P-38 pilot, Joseph J. Kaliszewski, flying for the General Mills Skyhook balloon program on balloon-tracking missions, saw highly unconventional objects on two successive days in October, 1951 (Refs. 5, 7, 10). Both were reported through company channels to the official investigative agency (Bluebook), whose report (Ref. 7) describes the witnesses as “very reliable” and as “experienced high altitude balloon observers.” On October 10, at about 10:10 a.m., Kaliszewski and Jack Donaghue were at 6000 ft in their light plane, climbing toward their target balloon, when Kaliszewski spotted “a strange object crossing the skies from East to West, a great deal higher and behind our balloon (which was near 20,000 ft. at that time).” When I interviewed Kaliszewski, he confirmed that this object “had a peculiar glow to it, crossing behind and above our balloon from east to west very rapidly, first coming in at a slight dive, leveling off for about a minute and slowing down, then into a sharp left turn and climbing at an angle of 50° to 60° into the southeast with a terrific acceleration.” The two observers had the object in view for an estimated two minutes, during which it crossed a span of some 45 of the sky. No vapor trail was seen, and Kaliszewski was emphatic in asserting that it was not a balloon, jet, or conventional aircraft. The following morning, near 0630, Kaliszewski was flying on another balloon mission with Richard Reilly and, while airborne north of Minneapolis, the two of them noticed an odd object. Quoting from the account submitted to the official agency (Ref. 7, Rept. No. 2) : “The object was moving from east to west at a high rate and very high. We tried keeping the ship on a constant course and using the reinforcing member

[[44]]

of the windshield as a point. The object moved past this member at about 50 degrees per second. This object was peculiar in that it had what can be described as a halo around it with a dark undersurface. It crossed rapidly and then slowed down and started to climb in lazy circles slowly. The pattern it made was like a falling oak leaf inverted. It went through these gyrations for a couple minutes and then with a very rapid acceleration disappeared to the east. This object Dick and I watched for approximately five minutes.” Shortly after, still another unknown object shot straight across the sky from west to east, but not before Kaliszewski succeeded in radioing theodolite observers at the University of Minnesota Airport. Two observers there (Douglas Smith, Richard Dorian) got fleeting glimpses of what appeared to them to be a cigar-shaped object viewed through the theodolite, but could not keep it in view due to its fast angular motion. In my conversations with Kaliszewski about these sightings, I gained the impression of talking with a careful observer, in full accord with impressions held by three other independent sources, including Air Force investigators. Discussion. — The October 10 sighting is officially categorized as “Aircraft,” the October 11 main sighting as “Unidentified.” When I mentioned this to Kaliszewski, he was unable to understand how any distinction could be so drawn between the two sightings, both of which he felt matched no known aeronautical device. Clearly, objects performing such intricate maneuvers are not meteors, nor can they be fitted to any known meteorological explanations of which I am aware. Instead, these objects seem best described as devices well beyond the state of 1951 (or 1968) technology. 5. Case 5. Willow Grove, Pa., May 21, 1966 Skipping over many other pilot observations to a more recent one which I have personally checked, I call attention to a close-range airborne sighting of a domed-disc, seen under midday conditions by two observers. One of them, William O. Powell, of Radnor, Pa., is a pilot with 18,000 logged flight hours. He and a passenger. Miss Muriel McClave, were flying in Powell’s Luscombe in the Philadelphia area on the afternoon of 5/21/66 when an object that had been first spotted as it apparently followed an outbound flight of Navy jets from Willow Grove NAS made a sharp (non-banking) turn and headed for Powell’s plane on a near-collision course. As the object passed close by, at a distance that Powell put at roughly 100 yards, they both got a good look at the object. It was circular in planform and had no wings or visible means of propulsion, both witnesses emphasized to me in interviews. The upper domed portion they described as “porcelain-white”, while the lower discoid portion was bright red (“dayglow red” Powell put it). It was slightly below their altitude as it passed on their right, and Powell pointed out that it was entirely solid, for it obscured the distant horizon areas. His brief comment about its solidity and reality was, “It was just like looking at a Cadillac.” He estimated its airspeed as perhaps 200 mph, and it moved in a steady, non-fluttering manner. He estimated its diameter at perhaps 20 feet. Miss McClave thought it might have been nearer 40 feet across. Each put the thickness-to-diameter ratio as about one-half. After it passed their starboard wing, Powell could see it only by looking back over his shoulder through a small aft window, but Miss McClave had it in full view when suddenly, she stated to me, it disappeared instantaneously, and they saw no more of it. Discussion. — Powell flies executive transports for a large Eastern firm, after years of military and airline duty. I have discussed the case with one of his superiors, who speaks without qualification for Powell’s trustworthiness. At a UFO panel discussion held on April 22, 1967 at the annual meeting of the American Society of Newspaper Editors, Powell was asked to summarize his sighting. His account is in the proceedings of that session (Ref. 30). I know of no natural phenomenon that could come close to explaining this sighting. The visibility was about 15 miles, they were flying in the clear at 4500 ft., and the object passed nearby. A pilot with 18,000 hours flight experience is not capable of precise midair distance and speed estimates, but his survival has probably hinged on not commonly making errors of much over a factor or two. Given the account and accepting its reliability, it seems necessary to say that here was one more case of what Gen. Samford described as “credible observers seeing relatively incredible objects”. I felt that Powell’s summary of his sighting at the ASNE meeting was particularly relevant because, in addition to my being on the panel there. Dr. D. H. Menzel and Mr. Philip J. Klass, both strong exponents of meteorological-type UFO theories, were present to hear his account. I cannot see how one could explain this incident in terms of meteorological optics nor in terms of ball

[[45]]

lighting plasmoids. Here again, we appear to be dealing with a meaningful observation of some vehicle or craft of non-terrestrial origin. Its reported instantaneous disappearance defies (as does the same phenomenon reported by J. B. Whitted and numerous other UFO witnesses) ready explanation in terms of present-day scientific knowledge. Powell reported his sighting at Willow Grove NAS, but it engendered no interest. 6. Case 6. Eastern Quebec, June 29, 1954. A case in which I have not been able to directly interview any witnesses, but about which a great deal is on record, through contemporary press accounts, through the pilot’s subsequent report, and through recent interviews by BBC staff members, occurred near Seven Islands, Quebec, just after sunset on 6/29/54. A BOAC Stratocruiser, bound from New York to London with 51 passengers, was followed for 18 minutes (about 80 miles of airpath) by one large object and six smaller objects that flew curious “formations” about it. The pilot of the Stratocruiser was Capt. James Howard, a highly respected BOAC flight officer still flying with BOAC. At the time, he had had 7500 flight hours. About 20 witnesses, including both passengers and crew, gave statements as to the unprecedented nature of these objects (Refs. 4, 10, and Associated Press wire stories datelined June 30, 1954). Discussion. — The flight was at 19,000 ft in an area of generally fair weather, with good visibility, attested by Howard and by weather maps for that day. No obvious optical or electrical explanation seems capable of accounting for this long-duration sighting. The objects were dark, not glowing, and their position relative to the sunset point precludes sundogs as an explanation. Mirage phenomena could not account for the eighty-mile persistence, nor for the type of systematic shape-changes described by the witnesses, nor for the geometrically regular formations taken up by the satellite objects as they shifted positions from time to time. Just before an F-86 arrived from Goose AFB at Howard’s request, First Officer Boyd and Navigator George Allen, who were watching the objects at that moment, said the small objects seemed to merge into the larger object. Then the large object receded rapidly towards the northwest and was out of sight in a matter of seconds. Such a maneuver of a number of satellite objects seeming to merge with or to enter a larger object has been reported in other UFO incidents around the world. 7. Case 7. Goshen, Ind., April 21, 1950 Another early airline sighting that seemed worth personally cross-checking involved the crew and passengers of a TWA DC-3 on the evening of 4/27/50 (Refs. 4, 5, 10, 23). I have interviewed both the pilot, Capt. Robert Adickes, and the copilot, Capt. Robert F. Manning, and confirmed all of the principal features first reported in detail in a magazine account by Keyhoe (Ref. 31). The DC-3 was at about 2000 ft, headed for Chicago, when, at about 8:25 p.m.. Manning spotted a glowing red object aft of the starboard wing, well to their rear. Manning sent to me a copy of notes that he had made later that night at his Chicago hotel. Quoting from the notes: “It was similar in appearance to a rising blood red moon, and appeared to be closing with us at a relatively slow rate of convergence. I watched its approach for about two minutes, trying to determine what it might be. I then attracted Adickes’ attention to the object asking what he thought it was. He rang for our hostess, Gloria Henshaw, and pointed it out to her. At that time the object was at a relative bearing of about 100 degrees and slightly lower than we were. It was seemingly holding its position relative to us, about one-half mile away.” Manning’s account then notes that Capt. Adickes sent the stewardess back to alert the passengers (see Keyhoe’s account, Ref. 31), and then banked the DC-3 to starboard to try to close on the unknown object. Manning continues in his 4/27/50 notes: “As we turned, the object seemed to veer away from us in a direction just west of north, toward the airport area of South Bend. It seemed to descend as it increased its velocity, and within a few minutes was lost to our sight …” Discussion. — Although, in my interview, I found some differences in the recollected shape of the object, as remembered by the two TWA pilots, both were positive it was no aircraft, both emphasized its red glow, and both were impressed by its high speed departure. Manning remarked to me that he’d never seen anything else like it before or since; and he conceded, in response to my query, that the decreased number of airline reports on UFOs in recent years

[[46]]

probably stems chiefly from pilot reluctance to report. Both be and Adickes, like most other pilots I have asked, indicated they were unaware of any airline regulations precluding reporting, however. I mentioned to Adickes that there is indirect indication in one reference (Ref. 5) that the official explanation for this sighting was “blast-furnace reflections off clouds.” He indicated this was absolutely out of the question. It is to be noted that here, as in many other pilot sightings, an upper bound, even if rough, is imposed on the range to the unknown by virtue of a downward-slanting line of sight. In such instances, meteor-explanations are almost automatically excluded. The Goshen case has no evident meteorological, astronomical, or optical explanation. 8. Case 8, Newport News, Va., July 14, 1952 Another case in which experienced pilots viewed UFOs below them, and hence had helpful background-cues to distance and size, occurred near 8:12 p.m. BST, July 14, 1952. A Pan American DC-4, en route from New York to Miami, was at 8000 ft over Chesapeake Bay, northeast of Newport News, when its cockpit crew witnessed glowing, disc-shaped objects approaching them at a lower altitude (estimated at perhaps 2000 ft). First Officer Wm. B. Nash, at the controls for Capt. Koepke (who was not on the flight deck during the sighting) and Second Officer Wm. H. Fortenberry saw six amber-glowing objects come in at high velocity and execute a peculiar flipping maneuver during an acute-angle direction-change. Almost immediately after the first six reversed course, two other apparently identical discs shot in under the DC-4, joining the other six. I am omitting here certain other maneuver details of significance, since these are on record in many accounts (4, 5, 10, 11, 25). Although I have not interviewed Nash (now in Germany with PAA, and Fortenberry is deceased), I believe that there has never been any dispute as to the observed facts. Nash has stated to T. M. Olsen (author of Ref. 11) that one of the most accurate accounts of the facts has been given by Menzel (Ref. 25), adding that Menzel’s explanation seems entirely out of the question to him. A half-dozen witnesses on the ground also saw unknowns at that time, according to official investigators. The objects had definite edges, and glowed “like hot coals”, except when they blinked out, as they did in unison just after the first six were joined by the latter two. When the lights came back on, Nash and Fortenberry saw them climbing westward, eight in line, north of Newport News. The objects climbed above the altitude of the DC-4 and then blinked out in random order and were seen no more. Discussion. — Menzel explains this famous sighting as resulting from a searchlight playing on thin haze layers, an almost entirely ad hoc assumption, and one that will not account for the amber color, nor for the distinct edges, nor for the final climb-out of the objects. The rapid motion, abrupt course-reversal, and the change from negative to positive angles of elevation of the line of sight to the unknowns seem to preclude any meteorological-optical explanation, and there is, of course, no possibility of explaining cases like this in terms of bail lightning, meteors, balloons, or many of the other frequently adduced phenomena. Nash has stated that he feels these were “intelligently operated craft” This case is officially “Unidentified.” 9. Many other pilot sightings, both recent and old, could readily be cited. Not only civilian pilots but dozens of military pilots have sighted wholly unconventional objects defying ready explanation (see esp. Ref. 10 and Ref. 7 for many such instances). Thus, the answer to the question, “Why don’t pilots see UFOs?” is: “They do.”

WHY ARE UFO’S ONLY SEEN BY LONE INDIVIDUALS? WHY NO MULTIPLE-WITNESS SIGHTINGS?

It is true that there are more single-witness UFO reports than multiple-witness cases. But, to indicate that by no means all interesting UFO reports entail lone witnesses, consider the following examples: 1. Case 9. Farmington, N.M., March 17, 1950 In the course of checking this famous case that made short-lived press headlines in 1950, I interviewed seven Farmington witnesses out of a total that was contemporarily estimated at “hundreds” to “over a thousand.” (Refs. 5, 25) It became clear from my interviewing that the streets were full of residents looking up at the strange aerial display that day. It was not only a multiple-witness case, but also a multiple-object case. My checking was done seventeen years after

[[47]]

the fact, so the somewhat confused recollective impressions I gained are not surprising. But that unidentified aerial objects moved in numbers over Farmington on 8/17/50 seems clear. One witness with whom I spoke, Clayton J. Boddy, estimated that he had observed a total of 20 to 30 disc-shaped objects, including one red one substantially larger than the others, moving at high velocity across the Farmington sky on the late morning of 8/17/50. John Baton, a Farmington realtor, described being called out of a barber shop when the excitement began and seeing a high, fast object suddenly joined by many objects that darted after it. Baton sent me a copy of an account he had jotted down shortly after the incident A former Navy pilot. Baton put their height at perhaps 15,000 ft. “The object that has me puzzled was the one we saw that was definitely red. It was seen by several and stated by all to be red and traveling northeast at a terrific speed.” Baton also spoke of the way the smaller objects would “turn and appear to be flat, then turn and appear to be round,” a description matching an oscillating disc-shaped object. No one described seeing any wings or tails, and the emphasis upon the darting, “bee-like” motion was in several of the accounts I obtained from witnesses. I obtained more details, but the above must suffice here for a brief summary. Discussion. — This once-headlined, but now almost forgotten multiple-witness case has been explained as resulting from the breakup of a Skyhook balloon (Ref. 25). Skyhooks do shatter at the very low temperatures of the upper troposphere, and occasionally break into a number of smaller pieces. But to suggest that such fragments of transparent plastic at altitudes of the order of 40-50,000 ft. could be detected by the naked eye, and to intimate that these distant objects of low angular velocity could confuse dozens of persons into describing fast-moving disc-shaped objects (including a large red object) is simply not reasonable. However, to check further on this, I contacted first Holloman AFB and then the Office of Naval Research, who jointly hold records on all Alamogordo Skyhook releases. No Skyhooks or other experimental balloons had been released from the Holloman area or any other part of the country on or near the date of this incident. A suggestion that the witnesses were seeing only cotton-wisps was not only unreasonable, given the witness accounts, but was in fact tracked down by a local journalist to comments casually made by a law enforcement officer and overheard by another reporter. From my examination of this case, I see no ready explanation for the numerous disc-shaped objects moving in unconventional manner and seen by large numbers of Farmington residents on 3/17/50. 2. Case 10. Longview, Wash., July 3, 1949 Many of the UFO cases I am citing are drawn intentionally from earlier years, in order to illustrate that the evidence for the existence of a quite real and scientifically significant phenomenon has been with us for a disturbing number of years. I discuss next a case on which I hold copies of material from the official investigative flies, copies that state that this incident was “observed by 150 other people at an Air Show”, in addition to the reporting witness, Moulton B. Taylor. I have interviewed Mr. Taylor and have obtained strong recommendations of his reliability from a former superior officer, Adm. D. S. Fahrney, under whom Taylor served in Navy guided missiles work prior to the incident. Taylor is an aeronautical engineer, and was airport manager at Longview, in charge of an air show that was to be held on the afternoon of 7/3/49, the day of the incident in question. A skywriting Stearman was at 10,000 ft. at 10:40 a.m., laying down “Air Show Today”, and hence holding the attention of a number of the personnel already at the airport, when the first of three unidentified objects flew over at high altitude. Alerted by one of the persons who first spotted the object coining from the northwest, Taylor got on the public address system and announced to all persons at hand that they should look up to see the odd object. Many had binoculars, and among the over 150 persons present were police officers, city officials and a number of Longview’s leading citizens, Taylor emphasized. The object was observed by a number of experienced pilots; and, according to official file summaries, all agreed that the object was shaped much like a discus. It seemed to have metallic luster and oscillated periodically as it crossed the sky from northwest to southeast until lost in mill-smoke. Taylor described the motion as a “sculling or falling-leaf motion rather than a movement through the axis of the disc.” Its angular size he estimated as about that of a pinhead at arm’s length, or about that of a DC-3 at 30,000 ft., both of which come out to be near 10 minutes of arc (one-third of moon’s diameter).

[[48]]

The crowd’s attention to events in the sky did not lapse when the first object was lost from view, and, about nine minutes later, someone spotted a second object, whereupon the event was again announced via the public address system. Still a third object was brought to the attention of the crowd in the same manner at 11:25. The second object came out of the north, the third came from almost due west. In the third case, someone thought of timing the oscillation frequency (all three exhibited the same unconventional oscillation, with sun-glint perceptible in certain of the instances of tipping, Taylor mentioned). The oscillation frequency was clocked at 48 per minute. In the official report are height estimates and some disparate comments on color, etc., from several other witnesses, as well as remarks on other sightings in the same area on the same day. Full details cannot be recounted here, for reasons of space limitation. Taylor, in his statement submitted to official investigators, said: “My experience in radio control of pilotless aircraft and guided missiles for the Navy at NAMU during the war, and over 20 years of aircraft study, does not permit my identification of the objects which were seen. They definitely were not balloons, birds, common aircraft, parachutes, stars, meteors, paper, clouds, or other common objects. They moved in a regular motion either straight or in curved lines. They were all at approximately the same altitude, but moved on different courses as indicated on the sketch. The oscillations were clearly visible and timed on the 3rd sighting ***.” Discussion. — The official explanation for this case is “Balloons”. I obtained information on upper winds over that part of Washington on that day (700 and 500 mb charts), and the flow aloft between 10,000 and 20,000 ft was from the southwest. The objects, all reported as about the same angular size, came from three distinctly different directions, all within a period of less than an hour. This immediately casts very strong doubt on the balloon hypothesis, as does the flipping motion, the sunglint, and, above all, the fact that no pilot balloon stations were located close upwind of Longview. Furthermore, a typical pilot balloon of about 1 meter diameter could be no higher than about 2500 ft altitude to subtend as large an angle as 10 minutes of arc. Taylor’s report (official flies) gave transit times of 2-3 minutes for the unknowns to cross the Longview sky, and, during such a time interval, the normal ascent rate of a pilot balloon would carry it up by 1200-1800 ft. To then fit the angular-size requirements would clearly require that the balloons have been released at some nearby location, which fails to match known pibal-station locations at that time. Furthermore, surface winds were from the west, and winds a short distance above the ground were southwesterly, as indicated by pulp mill smoke-drift described in Taylor’s report. This, plus the previously cited upper-flow directions, contradict the balloon hypothesis for all three directions of arrival, particularly those coming from north and northwest. To hypothesize that these were, say, Skyhook balloons coming from three different (unknown) sites, at three different high altitudes, but all so arranged that the apparent balloon diameter came out at about the same 10 minutes of arc each time is scarcely reasonable. In all, I can only regard the balloon explanation as untenable. Disc-shaped objects have been sighted in dozens of instances, including Arnold’s 6/24/47 Mt Rainier sighting. In many, though not all, the odd flipping or fluttering motion has been described by witnesses (Refs. 8, 10). What the dynamical significance of this might be is unclear. We know no more about this in 1968 than we knew in 1947, because such observations have been ignored as nonsense or misidentified balloons. 3. Case 11. Salt Lake City, Utah, Oct. 3, 1961 A midday sighting of a lens-shaped object involving one airborne witness and seven witnesses on the ground became headline news in Salt Lake City (Ref. 32). Accounts of the incident have been summarized elsewhere (Refs. 2, 10, 13, 25). A private pilot, Mr. Waldo J. Harris, was taking off on Runway 160 at Utah Central Airport at almost exactly noon on 10/2/61 when he noted what he at first idly viewed as a distant airplane. He noted it again in the same area just after becoming airborne, once more after gaining some altitude, and then became somewhat puzzled that it had not exhibited any appreciable change of position. About then it seemed to tilt, glinting in the noonday sun, and exhibiting a shape unlike any aircraft. To get a better view, Harris climbed towards the southeast and found himself at its altitude when he was somewhat above 6000 ft. By then it appeared as a biconvex metallic gray object, decidedly different from conventional aircraft, so he radioed back to the airport, where eventually seven persons were taking turns viewing it with binoculars. I have interviewed not only Harris,

[[49]]

but also Jay W. Galbraith, operator of the airport, who, with his wife, watched the object, and Robert G. Butler, another of those at the airport. As Harris attempted to close in, he got to a minimal distance that he thought might have been approximately two or three miles from the object, when it abruptly rose vertically by about 1000 ft, a maneuver confirmed by the ground witnesses. They indicated to me that it took only a second or perhaps less to ascend. Just before the abrupt rise, Harris had been viewing the object on an essentially dead-level line of sight, with distant Mt. Nebo behind it, a significant feature of the case, as will be brought out in a moment. Before Harris could close his distance much more, the object began moving off to the southeast at a speed well above his light-plane top speed. It was soon an estimated ten miles or so away, but Harris continued his attempt to close. However, after seeming to hover a short time in its new location, it began rising and moving westward, at an extremely rapid speed, and passed out of sight aloft to the southwest in only a few seconds. Some, but not all of the ground witnesses, observed this final fast climb-out, I was told. Military jets were called, but the object had gone before they arrived. Both Harris and the ground observers using binoculars attested to lack of wings or tail, and to the biconvex side view. Harris said he had the impression its surface resembled “sand-blasted aluminum,” but his closest view was about 2-3 miles away, and its estimated size was put at about 50-60 ft diameter (and only a tenth as thick), so the impression of surface texture must be regarded as uncertain. All witnesses confirmed that the object “wobbled” during its hovering. Jay Galbraith said that, when Harris’ Mooney Mark 20A was only a speck, they could see the disc rather easily by naked eye, suggesting that its size may have been substantially larger than Harris’ estimated 50 ft. Galbraith’s recollection of its final departure was that it climbed at a very steep angle, perhaps within about 20 of the vertical, he thought. Butler also recalled the final departure and stressed that it was a surprisingly steep climb-out, quite beyond any known jet speed. All remarked on 10/2/61 being a beautifully clear day. Discussion. — Once again we deal with observed performance characteristics far beyond anything of which we have present knowledge: a wingless device that can hover, shoot straight up, and move fast enough to pass out of sight in a matter of a few seconds does not correspond to any known terrestrial craft. The official explanation was originally that Harris saw Venus. From astronomical data, one finds that Venus was in the Utah sky at noon in early October, but lay in the southwest, whereas everyone’s line of sight to the object lay to the southeast. Furthermore, Harris’ statement that at one stage he viewed the disc against a distant mountain would contradict such an explanation. Finally, it is well known to astronomers that Venus, even at peak brilliance, is not very easily spotted in daytime, whereas he had no difficulty relocating it repeatedly as he flew. Menzel (Ref. 25) proposed that it was merely a sundog that Harris and the others were observing, and this was subsequently adopted as the official explanation. But sundogs (parhelia), for well-known reasons, occur at elevation angles equal to or slightly greater than the sun, which lay about 40° above the southern horizon at noon in Salt Lake that day. Such a solar position would imply that a sundog might have lain to the southeast (22° to the left of the sun), but at an elevation angle that completely fails to match Harris’ dead-level viewing (against a distant mountain, to further embarrass the sundog hypothesis). Finally, to check the witness’ statements about cloud-free skies. I checked with the Salt Lake City Weather Bureau office, and their logs showed completely clear skies and 40 miles visibility. Sundogs cannot occur without ice crystal clouds present. The only weather balloon released that morning was sent up at 10:00 a.m.; but in any event, one would have to write off almost all of the observed details to propose that this incident was a misinterpretation of a weather balloon. As I see it the 10/2/61 Salt Lake City sighting is just one more of the hundreds of very well-observed cases of machine-like craft exhibiting “flight performance” far beyond the state and present-day technology. 4. Case 12. Larson AFB, Moses Lake, Washington, January 8, 1953 NICAP’s recent publication of long-inaccessible official report-summaries (Ref. 7) makes readily available to interested scientists a large number of fascinating UFO reports. Many are in the multiple-witness category. For example, the dawn (0715 PST) sighting at Larson AFB where “over sixty varied military and civilian sources observed one green disc-shaped object. The observations continued for fifteen minutes during which time the object moved in a southwesterly direction while bobbing vertically and going sideways. There was no

[[50]]

sound. An F-84 aircraft was scrambled but a thirty minute search of the area produced negative intercept results.” The official summary also notes that the “winds were generally from 240° below an overcast at 13,000 ft. Thus the object would appear to move against the wind since it must have been below the clouds. There was no air traffic reported in the area.” No radar sites in the area had unusual returns or activity, according to the same report. Discussion. — This green disc, moving against the wind below an overcast and seen by over sixty witnesses, is an official Unidentified. 5. Case 13. Savannah River A.E.C Plant, Summer, 1952 A rather illuminating multiple-witness case was called to my attention by John A. Anderson, now at Sandia Base, New Mexico, but in 1952 working as a young engineer in the Savannah River AEC facility near Aiken, S.C. After a considerable amount of cross-checking on the part of both Anderson and myself, the date was inferred to be late July, 1952, probably 7/19/52. The circumstance giving a clue to the date was that, at about 10:00 a.m. on the day in question, Anderson, along with what he estimated at perhaps a hundred other engineers, scientists and technicians from his group were outside watching a “required attendance” skit presented from a truck-trailer and commemorating the 150th anniversary of the founding of the DuPont company, July 18, 1802. Anderson indicated that some less than absorbed in the skit first spotted the unidentified object in the clear skies overhead, and soon most eyes had left the skit to watch more technically intriguing events overhead. A greenish glowing object of no discernible shape, and of angular size estimated by Anderson to be not over a fifth of full-moon diameter, was darting back and forth erratically at very high speed. Anderson had the impression it was at great altitude, but conceded that perhaps nothing but the complete lack of sound yielded that impression. It was in view for about two minutes, moving at all times. He stressed its “phenomenal maneuverability”; it repeatedly changed direction abruptly in sharp-angle manner, he stressed. The observation was terminated when the object disappeared over the horizon “at apparently tremendous velocity.” Discussion. — Anderson said that the event was discussed among his group afterwards, and all agreed it could not possibly have been a conventional aircraft. He remarked that no one even thought of suggesting the unreasonable notion that it was an hallucination or illusion. Despite searching local papers for some days thereafter, not a word of this sighting was published, and no further information or comment on it came from within the very security-conscious AEC plant. He was unaware of any official report. Months after hearing of this from Anderson, in one of my numerous rereadings of Ruppelt’s book (Ref. 5), I came across a single sentence in which Ruppelt, referring to the high concentration of reports in the Southeast around September of 1952, states that: “Many of the reports came from people in the vicinity of the then new super-hush-hush AEC facility at Savannah River, Georgia.” Whether one of those reports to the official investigative agency came from within Anderson’s group or other Savannah River personnel on the 7/52 incident is unknown. If not, then we may have here a case where dozens of technically-trained personnel witnessed an entirely unexplainable aerial performance, yet reported nothing. Anderson knew of no report, and was unaware of any assembling of witness-information within his group, so the evidence points in the direction that this event may have gone unreported. If, as Anderson is inclined to think, this event was on July 19, 1952, it occurred only about twelve hours before the famous Washington National Airport radar-visual sightings; but this date remains uncertain. 6. Case 14. Trinidad, Colo., March 23, 1966 A daytime sighting by at least a dozen persons, in several parts of town, occurred near 5:00 p.m. on 3/23/66 in Trinidad, Colo. Following up a report in the APRO Bulletin on this interesting case, I eventually interviewed ten witnesses (seven children of average age near 12, and five adults). This case came just a few days after the famous “swamp gas” UFO incidents in southern Michigan, which made headline news all over the country. As APRO noted in its account, the Trinidad case seems in several respects a distinctly better case, yet went essentially unnoted outside of Trinidad. (Press reporting of UFO sightings leaves very much to be desired; I concur in the cited APRO comment. However,

[[51]]

press shortcomings in the UFO area are only secondary factors in the long failure to get this matter out into the open.) The witness-variance that skeptics like to cite is fairly well illustrated in the results of my ten interviews. I wish space permitted a full exposition of what each witness told me, for it would not only attest to that well-known variance but would also illustrate the point made earlier, namely, that despite those bothersome differences in details, there nevertheless comes through a consistent core of information on observations of something that was of scientific interest. Mrs. Frank R. Hoch paid no attention when her son first tried to call her out to see something in the sky. Knowing it was kite season, dinner preparations took precedence, and she told the 10-year-old boy to go ride his bike. The second time he was more insistent, and she went outside to look. Two objects, domed on the top but nearly flat on the bottom, shaped like a cup upside down, having no rim or “sombrero brim”, she said, were moving slowly westward from Fisher’s Peak, which lies just south of Trinidad. Her son, Dean, told her he had seen three such objects when he tried to get her to come out earlier. (Mr. Louis DiPaolo, a Trinidad postman whom I interviewed, had also seen three objects.) Interestingly, when Mrs. Hoch saw the objects, one was between her and the ridge, the other just above the low ridgeline. The ridge is about a half-mile from the Hoch residence. A photo of the ridge, with roughly-scaled objects sketched on it, suggests an angular diameter of perhaps a degree (object size of order 100 ft), in disagreement with her earlier angular estimates. It was clear that Mrs. Hoch was, as are most, unfamiliar with angular-size estimating. The objects, Mrs. Hoch said, moved up and down in a bobbing manner as they progressed slowly westward along the ridgeline. Occasionally they tilted, glinting in the late afternoon sun as if metallic. No sound was mentioned by any witness except one young boy whose attention was drawn to the object by a “ricocheting sound”, as he put it. DiPaolo’s observations were made with 7×35 binoculars; he also described the objects as metallic in appearance and shaped like a saucer upside down. His attention had been called to it by neighborhood boys playing outside. Mrs. Amelia Berry, in another part of Trinidad, evidently saw the objects somewhat earlier, when they were farther east, circling near Fisher’s Peak, but she was uncertain of the precise time. She saw only two, and remarked that they seemed to “glitter”, and she described them as “saucer shaped”, “oblong and narrow”. Mrs. J. R. Duran, horseback-riding with a 12-year-old son on the opposite (north) side of town also saw two objects, “flat on the bottom, and domed on top, silvery”, when her son called them to her attention. She described them as “floating along slowly, bobbing up and down, somewhat to the west of Fisher’s Peak.” She, like the other witnesses, was positive that these were not airplanes. No one described anything like wings or tail. A number of witnesses were so close that, had this been an unconventional helicopter, its engine-noise would have been unmistakable. Discussion. — Notwithstanding differences in the witness accounts (more of which would emerge from a more complete recounting), the common features of the observers’ descriptions would seem to rule out known types of aircraft, astronomical, meteorological, and other explanations. 7. Case 15, Redlands, Calif., February 4, 1968 A still more recent multiple-witness case of great interest was well-documented by three University of Redlands professors shortly after it occurred on the evening of 2/4/68. APRO plans a fairly detailed summary-report. Dr. Philip Seff kindly sent me a copy of the witness-testimony he and his colleagues secured in interviewing about twenty out of an estimated hundred-plus witnesses to this low-altitude sighting in a residential area of Redlands. Because I .understand that Dr. Harder will be giving a fairly detailed report of this case to your Committee. I shall give only a much-abbreviated version. At 7:20 p.m.. many persons went outdoors to investigate either (a) the unusual barking of neighborhood dogs. or (b) a disturbing and unusual sound. Soon many persons up and down several streets were observing an object round in planiform, estimated at perhaps 50-60 feet in diameter, moving slowly towards the east-northeast at an altitude put by most witnesses as perhaps 300 feet. Glowing ports or panels lay around its upper perimeter and “jet-like” orange-red flames or something resembling flames emanated from a number of sources on the undersurface. A number of odd psysiological [sic] effects were remarked by various witnesses, and the animal-reactions were a notable feature of this case. The object at one point rose abruptly by some hundreds of feet before continuing its somewhat “jerky” motion to the

[[52]]

east it then hovered a short time and moved off with acceleration to the northwest. Discussion. — The Redlands University trio inquired concerning radar detection, but were informed that the nearest radar was at March AFB, Riverside, and the beam clearing intervening ridges could not detect so low a target over Redlands. An interesting aspect of press coverage of UFOs, a very characteristic aspect, is illustrated here. The local Redlands-area papers carried only short pieces on the event; beyond that no press coverage occurred, as far as I have been able to ascertain. Evidently even the state wires did not carry it. (I think this fact deserves very strong emphasis. One has to see national clipping-service coverage, drawing upon many small-town papers, to gain even a dim glimpse of the astonishing number of UFO reports that occur steadily, but go unreported on state and national wires so that none but very diligent UFO investigators have any appreciation of the true frequency of UFO sightings. This is no “press clampdown”, no censorship; wire editors simply “know” that there’s nothing to all this nonsense about UFOs. A local story will be run simply for its local interest, but that interest falls off steeply with radial distance from the observation site.) Thus, we must confront a situation, developed over 20 years, in which over a hundred citizens in a city of about 30,000 population can see an utterly unconventional aerial machine just overhead and, almost by the time the dogs have stopped barking, press and officialdom are uninterested.; Dr. Seff told me just last week that he had encountered a Redlands University coed who had seen the object (he hadn’t interviewed her previously), and she seemed still terrified by the incident. I believe that your Committee must recognize an unfilled scientific obligation to get to the bottom of such matters. 8. Many other multiple-witness cases could be cited, some from my own interviewing experience, far more from other sources within this country and abroad. An October 28, 1954 sighting in Rome was estimated to have been viewed by thousands of people, one of whom was U.S. Ambassador Clare Booth Luce (Ref. 10) with her embassy staff. Mrs. Luce said it had the shape of a silver dollar and crossed the skies in about 30 seconds. A now-famous group of sightings of June 26/27, 1989, near Boianai, New Guinea, was observed by several dozen witnesses. the principal one of whom I interviewed in Melbourne, in 1967, Rev. Wm. B. Gill. Bloecher (Ref. 8) describes a number of mid-1947 incidents where the witness-totals ranged from dozens up to well over a hundred persons. Hall (Ref. 10) cites more recent instances. Many other sources could be cited to show that the intimation that UFOs are never seen except by lone individuals driving along some remote back road (a frequent setting, to be sure!) does not accord with the actual facts. Multiple-witness UFO cases are impressively numerous.

WHY AREN’T UFO’S EVER SEEN IN CITIES? WHY JUST IN OUT-OF-THE-WAY PLACES?

One cannot study the UFO problem long without being struck by the preponderance of reports that come from somewhat remote areas, non-urban areas. Similarly, one cannot escape the conclusion that more UFOs are reported at night than in day. For the latter, luminosity and its obvious effect on probability of chance visual detection may go far towards explaining the diurnal variation of UFO sightings (though I suspect that moat students of the problem would conclude that there is a real excess of nightttme occurrences for quite unknown reasons). Why, some ask with respect to the geographical distribution, don’t the UFOs, if real and if extraterrestrial, spend most of their time looking over our cities? That’s what we’d do, if we got to Mars and found huge urban complexes, some skeptics insist. It is surprising to find scientists who do not see through the transparency of that homocentric fallacy. If it were true that we were under surveillance from some advanced civilization of extraterrestrial origin, the pattern of the observations, the motivation of the surveillance, and the degree of interest in one versus another aspect of our planet could be almost incomprehensible to us. Aboriginal natives under anthropological observation must find almost incomprehensible the motives behind the strange things that the field-teams do, the odd things in which they are interested. But the cultural and the intellectual gulf that would separate us from any intelligent beings commanding a technology so advanced that they could cross interplanetary or interstellar distances to inspect us would be a gulf vastly greater than that which separates a Harvard field-anthropologist from a New Guinea native. And, for this reason, I think one must concede that, within the argumentation carried out under tentative consideration of an extraterrestrial

[[53]]

terrestrial hypothesis for UFOs, incomprehensibility must be expected as almost inevitable. Hence there is more whimsy than good reasoning in queries such as, “Why don’t they land on the White House lawn and shake hands with the President?” Nevertheless, the evidence affords a fairly definite answer to the skeptics’ question, “Why aren’t they ever seen over or in cities?” They are. 1. Case 16. New York City, November 22, 1966 A report in a 1967 issue of the NICAP UFO Investigator (Ref. 33) reads as follows; “A UFO over the United Nations in New York City was reportedly seen on November 22, 1966. Witnesses included at least eight employees of the American Newspaper Publishers Association, who watched from their offices on the 11th floor of 750 Third Avenue at 4:20 p.m. on a bright, sunny day. The UFO was a rectangular, cushion-shaped object …(which) came southward over the East River, then hovered over the UN Building … It fluttered an bobbed like a ship on agitated water.” Witnesses mentioned were D. B. McVay, assistant general manager of ANPA and Mr. W. H. Leick, manager of the ANPA’s Publications Department. I telephoned the ANPA offices and spoke at some length with Mr. Leick about the sighting. He confirmed that eight or nine persons went out on the 17th floor terrace, watching the object hover over the UN Building (as nearly as they could estimate) for a number of minutes as it rocked and reflected the sun’s rays with a golden glint before rising and moving off eastward at high speed. I asked Leick if they reported it to any official channels, and he said that A. A. LaSalle called a New York office of the Air Force and was assured that an officer would be in the next day to interview them. But no one ever came. Leick added that they also phoned a New York newspaper “which shall go unnamed,” but “they weren’t interested.” It got to NICAP almost by accident, and NICAP sent up their standard witness-questionnaires which Leick said they all filled out. Discussion. — When an incident such as this is cited to the skeptic who asks, “Why no UFOs near cities?”, I find that his almost invariable retort is something like: “If that had really happened, why wouldn’t hundreds to thousands of persons have reported it?” There are, I believe, two factors that explain the latter situation. First, consider the tiny fraction of persons on any city street whose vision is directed upwards at any given moment. In absence of loud noises aloft, most urbanites don’t spend any large amount of time scanning the skies. In addition to infrequency of sky-scanning, another urban obstacle to UFO detection is typically restricted vision of the full dome of the sky; buildings or trees cut down the field of view in a way not so typical of the view afforded the farmer, the forest ranger, or a person driving in open country. Finally. In UFO studies, it is always necessary to draw sharp distinction between a “sighting” and a “report”. The first becomes the second only if a witness takes the step of notifying a newspaper, a law-enforcement office, a university, or some official agency. It is abundantly clear, from the experience of UFO investigations in many parts of the world, that psychological factors centering around unwillingness to be ridiculed deter most witnesses from filing any official report on a very unusual event. Again and again one learns of a UFO sighting quite indirectly, from someone who knows someone who once mentioned that he’d seen something rather unusual. On following such leads, one frequently comes upon extremely significant sightings that were withheld from official reporting channels because of the “ridicule lid”, as I like to term it, that imposes a filter screening out a large number of good sightings at their source. Returning to the 11/22/66 New York City report, I must say that. between the information NICAP secured from the witnesses and my own direct conversations with Leick. I accept this as a quite real sighting, made by reliable observers under viewing circumstances that would seem to rule out obvious conventional explanations. When the object left its hovering location, it rose straight upward rapidly, before heading east, Leick said. Although he and his colleagues may well have erred in their slant-range estimate which put it over the UN Building, their description of its shape and its maneuvers would appear to rule out helicopters, aircraft, balloons, etc. 2. Case 17. Hollywood, Calif., February 5-6, 1960 A still more striking instance in which entirely unconventional objects were observed by many city-dwellers, where low-altitude objects hovered and exhibited baffling phenomena, is a central Hollywood case that was rather carefully checked by LANS, the Los Angeles NICAP Subcommittee (Ref. 34). The

[[54]]

two incidents occurred just after 11:00 p.m. on two successive nights, Friday 2/5/60 and Saturday 2/6/60, over or near the intersection of Sunset Blvd. and La Brea Ave., i.e., in the heart of downtown Hollywood. I have gone over the site area with one of the principal investigators of these incidents, Mrs. Idabel Epperson of LANS, have examined press accounts (Ref. 35) that dealt (very superficially) with the event, and have studied correspondence between the LANS investigators and official agencies concerning this case. The phenomenology is far too complex to report in full detail here; even the 21-page single-spaced LANS report was only a digest of results of all the NICAP witness-interviewing carried out to substantiate the events. The LANS report summarizes object-descriptions given by eight witnesses Friday night and eighteen witnesses Saturday night, several of them police officers. Cars were stopped bumper-to-bumper, according to employees of several businesses on the Sunset-La Brea intersection in the midst of the main events, with people gaping at the object overhead. Persons on hotel and apartment rooftops were out looking at the bright “cherry-red, circular light” that figured in both incidents. On the two successive nights, the red object first appeared at about 11:15 p.m., and on both nights it stopped and hovered motionless for periods of about 10 minutes at a time. The angular estimates of the size of the red light varied, but seemed to suggest a value of one-fourth to one-third of the lunar diameter, say 5-10 minutes of arc. Almost all agreed that the light was sharp-edged rather than hazy or fuzzy. The usual witness-variances are exhibited in the total of about two dozen persons interviewed, e.g., some thought the light pulsated, others recalled it as steady, etc., but the common features, consistent throughout almost all the testimony, bespeak a quite unusual phenomenon. On Friday night, the red light was first seen directly overhead at Sunset and La Brea. Two service-station attendants at that intersection, Jerry Darr and Charles Walker, described to LANS interviewers how, “… hundreds of people saw it — everybody was looking” as the light hovered for at least five minutes over a busy drive-in there. Ken Meyer, another service station attendant a third of a mile to the north, estimated it hovered for about 10 minutes. Harold Sherman, his wife, and two others watched it in the later phases (also described by the above-cited witnesses) as it resumed motion very slowly eastward. After proceeding east for a distance that witnesses roughly estimated at a block or two, it veered southeastward and passed out of sight. (It is not clear whether it was occulted by buildings for some witnesses, or diminished in intensity, or actually passed off into the distance.) No sound was heard over street-noise background. The following night, an object which appeared to be the same, to those several witnesses who saw both events, again showed up overhead, this time first seen about one block farther east than on Friday night. Triangulation based on estimates of angular elevations as seen from various locations was used to approximate the height above ground. LANS concluded that, when first seen, it lay about 500-600 ft. above the intersection of Sunset and Sycamore. A number of witnesses observed it hovering motionless in that position for about 10 minutes. Then a loud explosion and brilliant bluish-white flash was emitted by the object, the noise described by all witnesses as unlike any sonic boom or ordinary explosion they had ever heard. The sound alerted witnesses as far away as Curson and Hollywood Blvd., i.e., Tom Burns and two friends who asked LANS interviewers not to use their names. Condensing very greatly here the descriptions given to the interviewers by independent witnesses who viewed the “explosion” from various locations scattered over a circle of about a 1-mile radius yields a summary-description as follows: What had, just before the explosion, looked much “like a big red Christmas ball hanging there in the sky”, was suddenly the source of a flash that extended downward and to the west, lighting up the ground all around one interviewed (Soe Rosi) on La Brea Ave. A “mushroom-shaped cloud”, with coloration that impressed all who saw it, emerged upward and soon dissipated. Concurrently, as the red light extinguished, an object described by most, but not all, witnesses as long and tubular shot upwards. Angular estimates implied an object a number of tens of feet long, 70 ft. from Harold Sherman’s rough estimates. Clearly, it is difficult to explain how an object of such size could have materialized from a light at 500 ft. elevation and subtending an angle of only 10 minutes of arc, unless it had been there all along, unseen because of the brilliance of the red light beneath it. Or perhaps the angular-size estimates are in error. Some witnesses followed only the tubular ascending object, others saw

[[55]]

only something that “spiraled downwards” beneath the explosion source. No witness seemed certain of what it was that came down; some spoke of “glowing embers”; no one gave indication of following it to ground. Glossing over other details bearing on this “explosion” at an estimated 5-600 ft above Sunset and Sycamore, witnesses next became aware that the just-extinguished red light had evidently reappeared in a new location, about a block to the west. Police officers Bay Lopez and Daniel Jaffee, of LAPD, located at the corner of Sunset and LaBrea, heard the explosion and looked up, seeing the light in its new location “directly overhead”, as did many others at that intersection who then watched the red light hovering in its new location for about 3 minutes. (Space precludes my giving all pertinent information on time-estimates as set out in the 21-page LANS summary. For example, a good time-fix on the explosion came from the fact that E. W. Cass, a contractor living almost a mile west, was just winding his alarm clock, looking at it, when flare-like illumination “lit up the whole bedroom”, just at the indicated time of 11:30. He went out, watched the hovering red light in its new location, and added further details I shall omit here. Others took their time clues from the fact that 11:30 commercials had just come on TV when they heard the peculiar explosion and hastened outside to check, etc.) The red light, now over Sunset and La Brea, was roughly triangulated at about 1000 ft up, a figure in accord with several witness comments that, when it re-appeared some 4-5 seconds after the “explosion”, it lay not only somewhat west of its first location, but noticeably higher. After hovering there for a time inferred to be eight minutes, it began slowly drifting eastward, much as on the previous night when much less spectacular events had occurred. Larry Moquin, one witness who had taken rather careful alignment fixes using rooflines as an aid, remarked that, at this stage. La Brea and Sunset was filled with watchers: “Everybody was standing outside their cars looking up — cars were backed up in the streets — and everyone was asking each other, “What is it?” After moving slowly but steadily (observers mentioned absence of bobbing, weaving, or irregularity in its motion) for about a block east, to its first location it turned sharply towards the north-northeast, accelerated, and climbed steeply, not stopping again until at a very high altitude well to the north. From crude triangulation, LANS investigators inferred a new hovering altitude of over 25,000 ft, but it is clear from the data involved that this estimate is extremely rough. Discussion. — Although I have done no personal witness-interviewing to date in the 2/60 Hollywood case, I can vouch for the diligence and reliability with which the LANS group pursues its case-studies. The large number of interviews secured and the degree of consistency found therein seem to argue that some extremely unusual devices maneuvered over Hollywood on the two nights in question. Unless one simply rejects most of the salient features of the reports. it is quite clear that no meteorological or astronomical explanation is at all reasonable. Nor does any conventional aircraft match the reports. The question that arises almost immediately is that of a practical joke, a hoax. However, the resources required to fabricate some device yielding the complex behavior (stop motionless, move against wind, explosively emit secondary devices, and finally, in the 2/6 event, climb to rather high altitude) would scarcely be available to college pranksters. The phenomena go so far beyond the gas-balloon level of hoaxing that one must have some much more elaborate hoax hypothesis to account for the reported events. Balloons must drift with the winds, and the LANS group secured the local upper-wind data for both nights, and there is no match between the reported motions and the winds in the surface-1000-ft layer. And, in any event, the alternation between hovering and moving, plus the distinct direction-shifts without change of apparent altitude, cannot be squared with balloon-drift. This would mean that some highly controlled device was involved, capable (in the 2/6 incident) of hovering in an almost precisely stationary position relative to the ground (Moquin sighted carefully, using structural objects to secure a fix when the red light lay right over La Brea and Sunset, and perceived no motion for many minutes). Yet the Weather Bureau was reporting 5 mph winds from the southwest at 1000 ft (triangulated altitude when hovering there). Only if one hypothesized that this was an expensively elaborate experiment in psychological warfare could one account for financial resources needed to build a device capable of simulating some of these phenomena. Such a hypothesis seems quite unreasonable in the 100-megaton age where ever-present realities of weaponry pose more psychological strains than Disney-like pyrotechnics.

[[56]]

In fact, UFO sightings with equally peculiar phenomenology are so much a part of the total record that this Hollywood incident is not as unparalleled as it might first seem. In Hobard, Tasmania, I interviewed an electrical engineer who, along with a fellow engineer also employed by the Tasmanian Hydroelectric Commission, observed phenomena occurring in broad daylight over and near the River Derwent at Risdon that have the same “absurd” nature that one meets in the Hollywood case. The wife of a Texas rancher described to me an incident she witnessed in Juarez, Mexico, with about the same absurdity-quotient. We simply do not understand what we are dealing with in these UFO phenomena; my present opinion is that we must simply concede that, in the Hollywood case, we are confronted with decidedly odd UFO phenomena, in a decidedly urban locale. There appears to have been no official investigation of these striking events (Ref. 35), and local newspapers gave it only the briefest attention. In the New York City case cited above, the particulars were phoned to a large New York paper, but the paper was not interested, and no account was reported. Similarly in the 2/4/68 Redlands case, the local papers felt it warranted only an extremely brief article. This pattern is repeated over and over again; newspapermen have been led to believe that UFOs are really no more than occasional feature-story material. On rare occasions, for reasons not too clear to students of the UFO problem, some one case like the Michigan incident of 1966 will command national headlines for a day or two and then be consigned to journalistic limbo. This, in company with scientific rejection of the problem, plus official positions on the matter have combined to keep the public almost entirely unaware of the real situation with respect to frequency and nature of UFO incidents. For emphasis, let me repeat that I do not see design in that, nothing I construe as any well-planned attempt to keep us all uninformed for some sinister or protective reason. The longer I reflect on the history of the past handling of the UFO problem, the more I can see how one thing led to another until we have reached the intolerable present situation that so urgently calls for change. 3. Case 18. Baytown, Texas, July 18, 1966 Baytown, Texas, on Galveston Bay, has a population near 80,000. Several persons evidently saw an interesting object there at about 9:00 a.m. on 7/18/66. My original source on this case was an article that appeared in the 10/8/66 Houston Post from NICAP flies. The article, by Post reporter Jimmie Woods, represents one of those rare UFO feature stories in which fact is well blended with human interest, as I found when I subsequently interviewed one of the principal witnesses, W. T. Jackson, at whose service station he and assistant Kelly Dikeman made the sighting. Both were inside the station when Jackson spotted the object hovering motionless about 100 yards away. (The Post said 1000 yards, but Jackson pointed out that Woods interviewed him while he was waiting on customers at the station and the reporter didn’t get allot it correct.) Jackson explained to me that the object “lay right over the Dairy Queen.” He described it as a white object that “looked like two saucers turned together with a row of square windows in between”, and he thought it might have been 50 feet in diameter. He called Dikeman over, and they both looked at it for a few seconds and then simultaneously started for the door to get a better look. Almost at that moment it started moving westward. Dikeman was at the door before Jackson and had the last view of it as it passed over a water tower, beyond buildings and a refinery and was gone, “faster than any airplane.” Jackson described it as pure white, and definitely not spinning, since he saw clearly the features that he termed “windows” Jackson kept the incident to himself for a time; when it got out, two nurses who were unwilling to give him their names because “they didn’t want to be laughed at” stopped at his station and told him they had seen it from another part of Baytown. Discussion. — “Swamp gas” explanations were then still featured in press discussions of UFOs, and Jackson volunteered the comment that there are no swamps nearby and that it was “too high for any gas formations” he knew of. “It damned sure wasn’t no fireball,” Jackson told the Post reporter, and also commented, “Feller, when you set there and count the windows it ain’t no damn reflection.” I received similar salty commentary on various hypotheses when I spoke with Jackson. No sound was heard, yet, as Jackson put it, “if it had been any kind of jet, we’d have been deafened.” As in many other cases, a distinctly machine-like configuration, definite outlines, secondary “structural” features here termed “windows”, add up to a description that does not suggest any misinterpreted

[[57]]

natural phenomenon. That it hovered within a city of moderate size with only a total of two declared and two other undeclared witnesses is not entirely difficult to understand when one has interviewed large numbers of witnesses for whom the likelihood of ridicule was an almost sufficient deterrent to open reporting. 4. Case 19. Portland, Oregon, July 4, 1947 In the course of cross-checking a sampling of the 1947 cases that went into Bloecher’s study (Ref. 8), the numerous daytime sightings in central Portland on 7/4/47 seemed worth checking, especially because many of the reports came from police and harbor patrolmen. Here again, we deal with a case for which there are so many relevant details available that space precludes an adequate summary (see Ref. 8). I spoke with Sheriff’s Deputy Fred Krives who, along with several other deputies, had seen some of the many objects over Portland from the Court House across the Columbia River in Vancouver, Wash. Krives recalled that over half a dozen deputies were outside looking at what they estimated to be about 20 disc-shaped objects in several subgroups racing across the sky at an estimated height of perhaps 1000 ft, heading to the southwest. Both from contemporary press accounts and my own checks, it became evident that more than one formation of discs flew over Portland that day. Harbor Patrol Capt. K. A. Prehn, whom I located by telephone, told me that he had been called outside by another officer who spotted objects moving overhead towards the south. Their speed seemed comparable to that of aircraft, their outlines were quite sharp, and they looked metallic as they flashed in the sun. They occasionally wobbled, and their path seemed to be slightly irregular. Other officers with whom I spoke sighted discs from other parts of the Portland area; one of them, Officer Walter Lissy, emphasized that he recalled them as zig-zagging along at “terrific speed.” Another officer, Earl Patterson, told me of seeing a single object that “made sudden 90-degree turns with no difficulty.” I also obtained letter accounts from others in the Portland area who saw disc-like objects that day. Here was an early instance of unidentified objects maneuvering in full daylight over a major city. Discussion. — The July 4, 1947 sightings (for which Bloecher gathered press accounts for more than 80 from various parts of the U.S.) were made the subject of a good deal of press ridicule, as Bloecher’s study makes clear. However, after interviewing a number of the witnesses to the Portland sighting concerning their recollections of what they saw that day, I see no basis at all for rejecting these sightings. The official explanation for the Portland observations is “Radar Chaff,” based evidently (Ref. 6) on a report that some aircraft had made a chaff-drop in that area sometime on that day. “Chaff” is metal-foil cut into short strips, typically a few inches in length, ejected from military aircraft to jam radar. The strips float down through the air, intercepting and returning the radar pulses. To suggest that numerous police officers would confuse strips of foil, so small as to be invisible beyond a few hundred yards, with maneuvering disc-like objects seems unreasonable. I doubt that anyone who had talked directly to these officers could have seriously proposed such an explanation. Herein lies a difficulty: In an overwhelming majority of cases, official explanations have been conceived without any direct witness-interviewing on the part of those responsible for conceiving the explanations. 5. Perhaps, for present purposes, the foregoing cases will suffice to indicate that there have been significant UFO incidents in cities. Many other examples could easily be cited. Elsewhere (Ref. 2) I have discussed my interviews with witnesses in a case at Beverly, Mass., on the evening of April 22, 1966, where three adult women and subsequently a total of more than half a dozen adults (including two police officers) observed three round lighted objects hovering near a school building in the middle of Beverly. At one early stage of the sightings, one of the discs moved rapidly over the three women, hovering above one of them at an altitude of only a few tens of feet and terrifying the hapless women until she bolted. This case was quite thoroughly checked by Mr. Raymond B. Fowler, one of NICAP’s most able investigators, who has studied numerous other UFO incidents in the New England area. I interviewed witnesses in a most interesting sighting in Omaha in January 1966, where a stubby cigar-shaped object had been seen by a number of persons on the northwest side of the city. Urban UFO cases in other parts of the world are also a matter of at least journalistic if not yet scientific record. To sum up, though non-urban reports are definitely more numerous, urban reports do indeed exist.

WHY DON’T ASTRONOMERS EVER SEE UFO’S?

I have had this question put to me by many persons, including a number of astronomers. Once I was speaking to a group from an important laboratory of astronomy when the director asked why astronomers never see them. In the room, among his staff, were two astronomers who had seen unconventional objects while doing observing but who had asked that the information they had given me about their sightings be kept confidential. I understand such strictures, but some of them make things a bit difficult. This phenomenon of professional persons seeing unidentified objects and then being extremely loath to admit it is far more common than one might guess. After hearing of an evidently very significant sighting by a prominent physical scientist who was hiking in some western mountains when he spotted a metallic-looking disc, examined it with binoculars, and saw it shoot up into the air (according to my second-hand report from a professional colleague), I tried for month’s to secure a direct report of it from him; he was unwilling to discuss it openly with me. NICAP has had reports from prominent executives in large technical corporations who insisted that, just because of their positions, their names not be used publicly. Similar instances could be cited almost ad infinitum. The very types of witnesses whose testimony would carry greatest credence often prove to be the most reluctant to admit their sightings; they seem to feel they have the most to lose. Within a day of this writing I spoke to a veteran airlines pilot about a sighting in which he was involved about a decade ago. After the official “explanation” was publicized, he decided he’d never report another one. I predict that social psychologists are going to have a field day, in a few years, studying the “pluralistic ignorance” that led so many persons to conceal so many sightings for so long. Returning, however, to the question of why astronomers never see UFOs, a relevant quantitative consideration needs to be cited at once. According to a recent count, the membership of the American Astronomical Society is about 1800; by contrast, our country has about 350,000 law-enforcement officers. With almost 200 times as many police, sheriffs’ deputies, state troopers, etc., as there are professional astronomers, it is no surprise that many more UFO reports come from the law-enforcement officers than from the astronomers. Furthermore, the notion that astronomers spend most of their time scanning the skies is quite incorrect; the average patrolman almost certainly does more random looking about than the average professional astronomer. Despite these considerations, there are on record many sightings from astronomers, particularly the amateurs, who far outnumber the professionals. A few examples will be considered. 1. Case 20. Las Cruces, N.M., August 20, 1949 A good account of the sighting by Dr. Clyde Tombaugh, discoverer of the planet Pluto, is given by Menzel (Ref. 25). From my own discussions with Dr. Tombaugh, I confirmed the main outlines of this incident. At about 10:00 p.m. on 8/20/49, he, his wife, and his mother-in-law were in the yard of his Las Cruces home, admiring what Tombaugh described as a sky of rare transparency, when Tombaugh, looking almost directly towards zenith, spotted an array of pale yellow lights moving rapidly across the sky towards the southeast. He called them to the attention of the two others, who saw them just before they disappeared halfway to the horizon. The entire array subtended an angle which Tombaugh put at about one degree, and it took only a few seconds to cross 50 or 60 degrees of sky. The array comprised six “windowlike” rectangles of light, formed into a symmetric pattern; they moved too fast for aircraft, too slowly for a meteor, and made no sound. Menzel quotes Tombaugh as. saying, “I have never seen .anything like it before or since, and I have spent a lot of time where the night sky could be seen well.” Discussion. — Dr. Menzel explains this phenomenon as resulting from reflection of lights from the ground, possibly “the lighted windows of a house” reflected by an inversion or haze layer aloft. The movement he explains as resulting from a ripple on the haze layer. Such an “explanation” is not merely difficult to understand; it is incredible. For an “inversion layer” to produce such a near-normal reflection of window lights would demand a discontinuity of refractive index so enormously large compared with anything known to occur in our atmosphere as to make it utterly out of the question. However, it has been just such casual ad hoc explanations as this by which Menzel has, in his writings, used meteorological optics to rationalize case after ease with no attention to crucial quantitative details. It is a simple matter to show that even inversions of intensity many

[[59]]

orders of magnitude larger than have ever been observed yield reflectivities (at the kind of near-normal incidence involved in Tombaugh’s sighting) that are only a tiny fraction of one per cent (Ref. 36). In fact, I see no way of accounting for the Tombaugh observation in terms of known meteorological or astronomical phenomena. 2. Case 21. Ft. Sumner, New Mexico, July 10, 1947 A midday sighting by a University of New Mexico meteoriticist, Dr. Lincoln La Paz, and members of his family was summarized by Life magazine years ago (Ref. 87) without identifying La Paz’s name. Bloecher (Ref. 8) gives more details and notes that this is officially an Unidentified. (At 4:47 p.m. MST on 7/10/47, four members of the La Paz family nearly simultaneously noted “a curious bright object almost motionless” low on the western horizon, near a cloud bank. The object was described as ellipsoidal, whitish, and having sharply-outlined edges. It wobbled a bit as it hovered stationary just above the horizon, then moved upwards, passed behind clouds and re-emerged farther north in a time interval which La Paz estimated to be so short as to call for speeds in excess of conventional aircraft speeds. It passed in front of dark clouds and seemed self-luminous by contrast. It finally disappeared amongst the clouds. La Paz estimated it to be perhaps 20 miles away, judging from the clouds involved; and he put its length at perhaps 100-200 ft. Discussion. — This observation is attributed by Menzel (Ref. 24, p. 29) to “some sort of horizontal mirage, perhaps one of a very brilliant cloud shining like silver in the sunlight — a cloud that was itself invisible because of the darker clouds in the foreground.” As nearly as I am able to understand that explanation, it seems to be based on the notion that mirage-refraction can neatly superimpose the image of some distant object (here his “brilliant cloud”) upon some nearer object in the middle distance (here his “darker clouds”). That is a fallacious notion. If any optical distortions did here bring into view some distant bright cloud, it would not be possible to receive along immediately adjacent optical paths an image of the intermediate clouds. Furthermore, the extremely unstable lapse rates typical of the southwestern desert areas under afternoon conditions produce inferior mirages, not superior mirages of the looming type here invoked by Menzel. Rapid displacements, vertically and horizontally, are not typical of mirage phenomena. Hence Menzel’s explanations cannot be accepted for this sighting. 3. Case 22. Harborside, Me., July 8, 1947 An observation by an amateur astronomer, John F. Cole, reported to official investigative offices near the beginning of the period of general public awareness of the UFO problem, involves an erratically maneuvering cluster of about 10 objects, seen near 2:30 p.m. EDT on 7/3/47 on the eastern shore of Penobscot Bay. Hearing a roar overhead, Cole looked up to see the objects milling about like a moving swarm of bees as they traveled northwestward at a seemingly high speed, as nearly as he could judge size and distance. The objects were light-colored, and no wings could be discerned on most, although two appeared to have some sort of darker projections somewhat resembling wings. In 10-15 seconds they passed out of sight Discussion. This is one of several dozen cases admitted to the Unidentified category in one of the earliest official reports on UFOs (Ref. 6). I have tried, unsuccessfully, to locate J. F. Cole. An account of the case is given by Bloecher (Ref. 8). It might be remarked that “swarming bee” UFO observations have cropped up repeatedly over the years, and from all over the world. 4. Case 23. Ogra, Latvia, July 26, 1965 An astronomer whom I know recently toured a number of observatories in the USSR, and brought back the word that a majority of Russian astronomers have paid little attention to Russian UFO reports (details of which are quite similar to American UFO reports, my colleagues established), a frequently-cited reason being that the American astronomer, Menzel, had given adequate optical explanations of all such sightings. I must agree with Dr. Felix Zigel who, writing on the UFO problem in Soviet Life (Ref. 38), remarked that Menzel’s explanation in terms of atmospheric optics “does not hold water.” It would, for example, be straining meteorological optics to try to account in such terms for a sighting by three Latvian astronomers whose report Zigel cites in his article. At 9:35 p.m. on 7/26/65 while studying noctilucent clouds, R. Vitolniek and two colleagues visually observed a starlike object drifting slowly westward. Under 8-power binocular

[[60]]

magnification, the light exhibited finite angular diameter, so a telescope was used to examine it. In the telescope, it appeared as a composite of four smaller objects. There was a central sphere around which, “at a distance of two diameters, were three spheres resembling the one in the center.” The outer spheres slowly rotated around the central sphere as the array gradually moved across the sky, diminishing in size as if leaving the Earth. After about 20 minutes’ observation, the astronomers noted the outer spheres moving away from the central object, and by about 10:00 p.m., the entire group had moved so far away that they were no longer visible. Discussion. — I have no first-hand information on this report, of course. The group of objects was seen at an angular elevation of about 60 degrees, far too high to invoke any mirage-effects or other familiar refractive anomalies. Furthermore, the composite nature of the array scarcely suggests an optical distortion of the telescope, a possibility also rendered improbable from the observed angular velocity and apparent recessional motion. 5. Case 24. Kislovodsk, Caucasus, August 8. 1967 Zigel, who is affiliated with the Moscow Aviation Institute, reports in the same article (Ref. 38), a sighting at 8:40 p.m., 8/8/07, made by astronomer Anatoli Sazanov and colleagues working at the Mountain Astrophysical Station of the USSR Academy of Sciences, near Kislovodsk. Sazanov and ten other staff members watched an “asymmetric crescent, with its convex side turned in the direction of its movement” moving eastward across the northern sky at an angular elevation of about 20 degrees. Just ahead of it, and moving at the same angular speed was a point of light comparable to a star of the first magnitude. The crescent-like object was reddish-yellow, had an angular breadth of about two-thirds that of the moon, and left vapor-like trails aft of the ends of the crescent horns. As it receded, it diminished in size and thus “instantly disappeared”. Discussion. — If we may accept as reliable the principal features of the sighting, how might we account for it? The “faintly luminous ribbons” trailing from the horns suggest a high-flying jet, of course; but the asymmetry and the reddish-yellow coloration fail to fit that notion. Also, it was an object of rather large angular size, about 20 minutes of arc, so that an aircraft of wingspan, say, 150 feet would have been only about five miles away whence engine-noise would have been audible under the quiet conditions of a mountain observatory. More significant, if it had been an aircraft at a slant range of five miles, and at 20 degree elevation, its altitude would have been only about 9000 ft above the observatory. For the latitude and date. the sun was about ten degrees below the western horizon, so direct sun-illumination on the aircraft at 9000 ft above observatory level would be out of the question. Hence the luminosity goes unexplain . Clearly, satellites and meteors can-be ruled out. The astronomers’ observation cannot be readily explained in any conventional terms. Zigel remarks that the object was also seen in the town of Kislovodsk, and that another reddish crescent was observed in the same area on the evening of July 17, 1967. 6. Case 25. Flagstaff, Ariz., May 20, 1950 Near noon on 5/20/50, Dr. Seymour Hess observed an object from the grounds of the Lowell Observatory. Although Hess’ principal field of interest has been meteorology, we may here consider him an astronomer-by-association, since he was at Lowell doing work on planetary atmospheres, on leave from Florida State University. Spotting an unusual small object moving from SE to NW, he had time to send his son after binoculars, which he used in the later portions of his observation. He said it looked somewhat disc-shaped, or perhaps somewhat like a tipped parachute. It had no wings or visible means of propulsion, Dr. Hess indicated to me that he probably had it in sight a total of about three minutes, during which it passed directly between him and a cloud, before disappearing (into a cloud Hess feels, though this point was not certain). From meteorological data bearing on the cloud-base height, Hess deduced that the cloud bases lay 12,000 ft above terrain (vs. Weather Bureau visual estimate of 6000 ft above terrain). The zenith angle was about 48 degrees, so the slant range would have been 17,000 ft or 8,000 ft, depending on which cloud height is accepted. For its 3 minutes estimated angular diameter (dime at 50 ft Hess estimated), the diameter would then come out of the order of 10 to 15 feet His subjective impression was that it was possibly smaller than that. Discussion. — The possibility that this might have been a balloon or some other freely drifting device comes to mind. However, Hess noted carefully that the clouds were drifting from SW to NE, i.e., at right angles to the object’s motion.

[[61]]

He estimated its speed to be in the neighborhood of 100 to 200 mph, yet no engine noises of any kind were audible. It appeared dark against the bright cloud background, but bright when it was seen against blue sky. No obvious explanation in conventional terms seems to fit this sighting. 7. Many other sightings by both professional and amateur astronomers could be listed. Vallee (Ref. 17) discusses in detail a November 8, 1957 observation by J. L. Chapuis of Toulouse Observatory in France of what appeared through a small telescope to be a yellowish, elliptical body, with distinct outlines, leaving a short trail behind it. It was seen by other observers in three separate locations, executed maneuvers entirely excluding meteoric origin, and was regarded as an unexplainable phenomenon by all of the witnesses. Hall (Ref. 10) lists nine examples of astronomer sightings of unidentified objects, several of which are quite striking. Ruppelt (Ref. 5) remarks that an astronomer working under contract to the official UFO investigatory program interviewed 45 American astronomers uring the summer of 1952, of whom five (11 per cent) had seen what they regarded to be UFOs. Although the sample is small, that percentage is well above the population percentage who say they have seen UFOs, which suggests that perhaps astronomers may sight more UFOs than they report as such. Indeed, with the recent publication of Ref. 7, further interesting information on that 1952 poll is now at hand. The contract astronomer wrote at that time (Ref. 7, Rept 8), “… certainly another contributing factor to their desire not to talk about these things is their overwhelming fear of publicity. One headline in the nation’s papers to the effect that ‘Astronomer Sees Flying Saucer’ would be enough to brand the astronomer as questionable among his colleagues.” Unfortunately, we scientists are by no means as open-minded and fearlessly independent as we are sometimes pictured. It is often quite difficult to persuade a scientist to let his confidential report of a UFO sighting become a fully open UFO report; and my own experience suggests that perhaps astronomers, as a group, are just a bit more sensitive on this score than other scientists. At any event, perhaps the above-cited cases will suggest that some astronomers have seen unidentified flying objects.

METEOROLOGISTS AND WEATHER OBSERVERS LOOK AT THE SKIES FREQUENTLY. WHY DON’T THEY SEE UFOS?

1. Case 26. Richmond, Va., April 1947 To begin an answer to that rhetorical question, we might consider an observation made by a weather observer at the Richmond, Va., U.S. Weather Bureau station, about two months before the first national publicity concerning UFOs. Walter A. Minczewski, whom I located at the same Weather Bureau office where he made the sighting in 1947, was making a pilot balloon observation, when he spotted a silvery object that entered the field of his theodolite (which was trained on the balloon he had released). In the account that Minczewski sent me, he stated that “the bottom was flat and the top was slightly dome-shaped”: and when he tried to see it with naked eye, he could not spot it. (Typical pilot balloon theodolites have magnifications of about 20 to 25. and angular fields that are usually about a degree across.) It was a “clear bright morning” when he spotted the object, and it lay to his NNE at an elevation of about 45 degrees. Whether Minczewski really saw the upper surface or formed his mental impressions without realizing that the theodolite may have inverted the image is now unclear, and my questioning did not settle that point. Discussion. — A report of this sighting is in the official files, a circumstance which greatly surprised Minczewski, since he had discussed it only with his fellow workers. In the ensuing two decades, he has never again seen anything like it. Clearly, the probability of an object crossing the small angular field of a meteorological theodolite is quite low, if only chance were involved here. He tried to track it but lost it, due to its high angular velocity, after about five or six seconds, he recalled. No obvious conventional explanation suggests itself for this early sighting. 2. Case 27. Yuma, Ariz., February 4, 1953 Weather Bureau observer S. H. Brown was tracking a pilot balloon at 6000 ft over Yuma at 1:50 p.m. MST on 2/4/53 when first one and then a second unidentified object moved across his theodolite field, somewhat as in the preceding case. I obtained an account of this sighting from V. B. Gotten, Meteorologis in-Charge at the Yuma station. The full account is too long for recapitulation here. Both objects appeared to be of the order of a minute of arc in diameter

[[62]]

and appeared “almost round, a solid dull pure white color, with a thin white mist completely edging each object.” The first object moved into the optical field and curved upwards to the west, with the theodolite oriented to about 53 degrees elevation, 107 degrees azimuth. About 20 seconds later, a second object entered the field and moved in and out of the field erratically two times, to rejoin the first object. Brown was able to track the pair thereafter, as they jointly changed both azimuth and elevation. Because he had a stopwatch at hand for the balloon observation (which he did not complete because of following the unknown objects), he was able to determine that he followed the pair of objects for five minutes (1350 to 1355), until he lost sight of them against a cirrus cloud deck to the SSW. At the termination of the observation, his instrument was pointed to 29 degrees elevation, 204 degrees azimuth. Discussion. — This case is carried as Unidentified in the official files (see Ref. 7 for official summary). At times these objects lay near the sun’s position in the sky, which might suggest forward-angle scattering of sunlight by airborne particles. However, initially, the objects were detected at angular distance of about 40 degrees from the solar position, which would not yield appreciable low-angle scattering. Furthermore, if these were airborne scatterers, they would almost certainly be separated by random turbulence within as long a period as five minutes, yet the observer’s report indicates that they maneuvered together within angular separations of the order of the roughly one-degree field of such theodolites. The fact that the second object did go out of the field only to return to the vicinity of the first object strains the airborne-particle hypothesis. Thus the official categorization of Unidentified seems reasonable here. 3. Case 28. Upington, Cape Province, December 7, 1954 R. H. Kleyweg, Officer-in-Charge of the Upington Meteorological Station, had just released a balloon for upper-wind measurement and was shielding his eyes from the sun trying to spot the balloon to get his theodolite on it. Seeing an object east of the sun, moving slowly to the west, he thought it was his balloon and got the theodolite on it, only to find that it was white, whereas he had released a red balloon. An account in the Natal Mercury, January 28, 1950, quoted Kleyweg as saying that it seemed “like a half-circle with the sun reflecting off the sloping top.” He had no difficulty following it for about three minutes, but then it began to accelerate and, after another minute, he was unable to track fast enough to keep it in optical view (Ref. 10). Discussion. — Kleyweg was quoted in the cited press source as saying, “I have followed thousands of meteorological balloons. This object was no balloon. ” A South African student doing graduate work in my Department, Petrus DuToit, has confirmed this sighting, having had an account of it directly from Kleyweg. An accelerating airborne half-circular object with sloping top seems best categorized as an unidentified flying object. 4. Case 29. Arrey, New Mexico, April 24, 1949 Charles B. Moore, Jr., was with four enlisted Navy personnel making a pilot balloon observation preparatory to release of a Skyhook balloon at the White Sands Proving Ground in the middle of the morning of 4/24/49. The balloon was airborne and was under observation by one of the men when Moore became aware that a white object which he took to be the balloon was in a part of the sky well away from where the theodolite operator had this instrument trained. As Moore has explained directly to me in discussing this famous case, he thought the operator had lost the balloon. Moore took over, swung the 25-power scope onto the “balloon” he had spotted, and found that it was in fact an ellipsoidal white object moving at a rapid angular velocity towards the NE. With stopwatch and recording forms at hand, it was possible for the team of five men to secure some semi-quantitative data on this sighting; Moore disengaged the vernier drives to track manually, and followed the object as it sped from the southwest into the northeast skies. At its closest approach, it was moving at about 5 degrees/sec. Just before Moore lost it in the distance to the northeast, its angular elevation began to increase, as if it were climbing, a quite significant point. The object had a horizontal length about two to three times greater than its vertical thickness. Moore never got a sufficiently clear view to identify any finer details if any were present. Another balloon was immediately released to check the slim possibility that a high-speed jet from SW to NE might have carried some airborne object across the sky; but the winds were blowing more or less at right angles to the object’s path to the 93,000 ft level, and were rather weak (Ref. 10). The angular diameter of the object was estimated at about a

[[63]]

minute of arc (which in the 25-power theodolite would appear to Moore as about three-fourths the apparent size of the moon ). Discussion. — Moore’s sighting is carried as Unidentified in official files. Menzel (Ref. 24)says of it: “This incident, kept in the classified files for more than two years, presents no serious difficulty to the person who understands the optics of the earth’s atmosphere. The air can, under special conditions, produce formations similar to lenses. And, just as a burning glass can project the sun into a point of light, so can these lenses of air — imperfect though they are — form an image. What Moore saw was an out of focus and badly astigmatic image of the balloon above” It would be interesting to hear Menzel present a quantitative defense of that astonishing disposition of this interesting sighting. Here five witnesses, with aid of a tracking device giving better than rough angular-coordinate information on the movements of an unknown object, observe the object move through an arc of over 90 degrees that took it into a part of the sky about that same large angular distance from the real balloon’s location, and Menzel adduces a “lens of air” to explain it away. Astronomers find atmospheric scintillation a very serious observational problem because stellar images are often erratically shifted by tens of seconds of arc from their mean position as a result of atmospheric turbulence effects. In the 5/24/49 Moore sighting, Menzel is proposing that the atmosphere carried a refracted image of the balloon northeastward at a steady rate of excursion that finally totaled several thousand times the magnitude of refractive angular image-displacements known to occur with bad seeing. I feel obliged to repeat an observation I have made before: If the transmission properties of the Earth’s atmosphere were as anomalous as Menzel assumes in his handling of UFO observations, he and his colleagues would be out of business. The official categorization of Unidentified for the Moore sighting seems inescapable. It might be added that, over the years, there have been very many UFO observations of significant nature from the vicinity of White Sands Proving Ground, many involving instrumental tracking, many made by experienced observers. A long and impressive list of them could easily be compiled, yet all have been slowly lost from official cognizance by a process that is characteristically at the heart of response to the UFO problem. 5. Case 30. Admiralty Bay, Antarctica, March 16, 1961. This listing of UFO sightings by meteorologists could be extended very considerably by drawing on my file of such cases. To cite just one more that also indicates the global .scale of the UFO phenomena, a very unusual luminous unidentified aerial object seen by a meteorologist and others aboard the U.S.S. Glacier at about 6:15 p.m. on 3/16/61 in the Antarctic will be mentioned. I have quite recently received, through French UFO investigator Rene Fouere, a rather detailed summary of this sighting by Brazilian meteorologist Rubens J. Villela, whose earlier account I had seen but paid little attention to (Ref. 10). The point I had missed, prior to reading Villela’a detailed description of the circumstances of the sighting, was the very important feature of a low cloud overcast present at about 1500 ft above the sea. With three shipmates on the flying bridge, Villela suddenly saw “a multicolored luminous object crossing the sky,” an object which for a moment they took to be an unusual meteor. “It was egg-shaped, colored mainly reddish at first, and traveled slowly from NE to SW at about 50 degrees above the horizon, on a straight horizontal trajectory. From its frontal part, several multicolored, perfectly straight ‘rays’ extended backwards, diverging outwards at an angle; the colors of these rays changed continually, predominantly green, red, and blue. Most striking of all, it left a long trail of orange color in the form of a perfectly straight tube which gave the distinct impression of being hollow, faintly comparable to a neon light,” Villela stated in his summary. “Then, suddenly the object divided in two. It was not an explosion, it was a controlled division in two equal parts, one behind the other, each egg-shaped as before and each radiating outwards its V-shaped lateral rays. Then the object shone with a slightly stronger light, changing color to blue and white, and disappeared completely. That’s it — just disappeared, abruptly.”

[[64]]

His account emphasizes that the boundaries of the object (s) were definite and sharp, not diffuse. Villela’s account indicates that a total of six persons were above-decks and saw this striking phenomenon. It is to be emphasized that, in the estimated 10 seconds that this lasted, the object was moving below a cloud deck that lay only about 1500 feet above the sea, so that, for the reported elevation angle of about 50 degrees, the slant range from observers to object was perhaps of the order of 2000 ft. Villela had the subjective impression that the egg-shaped initial form was about as big as a small airplane. Discussion. — In a recent book aimed at showing that a majority of the most interesting UFOs are an atmospheric-electrical plasma related to ball lightning, Philip J. Klass (Ref. 39)) cites the preceding case as a good example of the port of observation which he feels he can encompass in his “plasma-UFO” hypothesis. To the extent that he treats only the breakup into two parts, he has some observational basis for trying to interpret this as something akin to ball lightning. But almost at that point the similarity ends as far as meteorologically recognized characteristics of ball lightning go. The highly structured nature of the object and its rays, its size, its horizontal trajectory, its presence in a foggy area with low stratiform clouds free of thunderstorm activity scarcely suggest anything like ball lightning. Nor does this account suggest any meteoric phenomenon at sub-cloud altitudes. I would regard this as just one more of a baffling array of inexplicable aerial phenomena which span so wide a range of characteristics that it is taxing to try to invent any single hypothesis to rationalize them all. The full spectrum of UFO phenomena will, I predict, come as a shock to every scientist who takes the necessary time to look into the wealth of reports accumulated in various archives over the past two decades and more. Official assertions to the effect that UFO reports in no way defy explanation in terms of present scientific and technological knowledge are, in my opinion, entirely unjustified. The Villela sighting seems a case in point. And meteorologists do see UFOs, as the foregoing cases should suggest.

DON’T WEATHER BALLOONS AND RESEARCH BALLOONS ACCOUNT FOR MANY UFOS?

Probably the most categorical statement ever made attributing UFO observations to balloons appeared in a Look magazine article by Richard Wilson in February 1051, entitled, “A Nuclear Physicist Exposes Flying Saucers.” Dr. Urner Liddel. then affiliated with the Navy cosmic ray research program using the large Skyhook balloons, was quoted as saying, “There is not a single reliable report of an observation (of a UFO) which is not attributable to the cosmic balloons.” When one considers the large number of UFO reports already on record by 1951 in which reliable airlines pilots, military personnel, and other credible witnesses have observed unidentified objects wholly unlike a high-altitude, slowly drifting pear-shaped Skyhook balloon, that assertion appears very curious. Nevertheless, that many persons have misidentified Skyhook balloons and even the smaller weather balloons used in routine meteorological practice is unquestioned. A Skyhook seen against the twilight sky with back-illumination yields a strangely luminous, hovering object which many observers, especially if equipped with binoculars, were unprepared to identify correctly in the 1946-51 period when Skyhook operations were tied up with still-classified programs. To this extent, Liddel’s point is reasonable; but his sweeping assertion fails to fit the facts, then or now. Actually, in official case-evaluations, one finds Skyhook balloons invoked relatively infrequently compared with “weather balloons,” But in many of the latter cases, the balloon hypothesis is strained beyond the breaking point. The official criterion used (Ref. 7, p. 185) is extremely loose: “If an object is reported near a balloon launch site within an hour after the scheduled launch times, it is classed as a balloon.” with no specification of heights, shapes, distances, etc. Using such a criterion, it is easy to see why so many “balloon” explanations figure in the official summaries. There are even “balloon” UFOs whose speed, when inferred from the report, comes out supersonic! The tiny candles or flashlight bulbs hung on pilot balloons for night tracking have been repeatedly made the basis for explanations of what witnesses described as huge luminous objects at close range. Within only days of this writing, I have checked out such a case near Tucson where four adult witnesses saw, on July 2, 1968, a half-moon-shaped orange-red object hovering for several minutes at what they estimated to be a few hundred feet above terrain and perhaps a few miles away over open desert. They watched it tip once, right

[[65]]

itself, then accelerate and rise over a mountain range and pass off into the distance in some ten seconds. Because a weather balloon had been released earlier (actually about an hour and forty-five minutes earlier) from the Tucson airport Weather Bureau station, the official explanation, published in the local press, was that the witnesses had seen a “weather balloon”. A pilot balloon of the small type (30-gram) used in this instance rises at about 600 ft/min, the tiny light on it becomes invisible to the naked eye beyond about 10,000 ft slant-range, and the upper-level winds weren’t even blowing toward the site in question. Also the angular size estimated for the observed reddish half-moon was about twice the lunar diameter, and some said about four times larger. A pilot balloon light would have to be within about 20-30 feet to appear this large. Yet such a case will enter the files (if even transmitted to higher echelons) as a “balloon”, swelling the population of curious balloon-evaluations in official files. 1. Case 31. Ft. Monmouth, N.J., September 10, 1951 It is clear from Ruppelt’s discussions (Ref. 5) that a series of radar and visual sightings near Ft. Monmouth on 9/10/51 and the next day were of critical importance in affecting official handling of the UFO problem in the ensuing two-year period. Many details from the official file on these sightings are now available for scientific scrutiny (Ref. 7). Here, a sighting by two military airmen flying in a T-33 near Ft. Monmouth will be selected from that series of events because the sighting was eventually tagged as a weather balloon. As with any really significant UFO case, it would require far more space than can be used here to spell out adequately all relevant details, so a very truncated account must be employed. While flying at 20,000 ft from a Delaware to a Long Island airbase, the two men in the T-33 spotted an object “round and silver in color” which at one stage of the attempted intercept appeared flat. The T-33 was put into a descending turn to try to close on the object but the latter turned tightly (the airmen stated) and passed rapidly eastward towards the coast of New Jersey and out to sea. A pair of weather balloons (probably radiosonde balloons but no information thereon given in the files) had been released from the Evans Signal Laboratory near Ft. Monmouth, and the official evaluation indicates that this is what the airmen saw. However, it is stated that the balloons were released at 1112 EDST, and the sighting began at about 1130 EDST with the T-33 over Point Pleasant, N.J. In that elapsed time, a radiosonde balloon, inflated to rise at the 800-900 ft/min rate used for such devices, would have attained an altitude of about 17-18,000 ft, the analysis notes. From this point on, the official analysis seems to be built on erroneous inferences. The airmen said that, as they tried to turn on the object, it appeared to execute a 120-degree turn over Freehold, N.J., before speeding out over the Atlantic. But from the upper winds for that day, it is clear that the Ft. Monmouth balloon trajectory would have taken it to the northeast, and by 1130, it would have been about over the coast in the vicinity of Sea Bright. Hence, at no time in the interval involved could the line of sight from T-33 to balloon have intersected Freehold, which lies about 15 miles WSW of the balloon release-point. Instead, had the airmen somehow seen the radiosonde balloon from Pt. Pleasant, it would have lain to about their N or NNE and would have stayed in about that sector until they passed it. Furthermore, the size of the balloon poses a serious difficulty for the official analysis. Assuming that it had expanded to a diameter of about 15 feet as it ascended to about the 18,000-ft level, it would have subtended an arc of only 0.6 min, as seen from the T-33 when the latter passed over Pt. Pleasant. This angular size is, for an unaided eye, much too small to fit the airmen’s descriptions of what they tried to intercept. In a press interview (Ref. 40), the pilot, Wilbert S. Rogers of Columbia, Pa., said the object was ”perfectly round and flat” and that the center of the disc was raised “about six feet” and that it appeared to be moving at an airspeed of the order of 900 mph. The entire reasoning on which the balloon evaluation is elaborated fails to fit readily established points in the official case-summary. Discussion. — The possibility that a pilot can be misled by depth-perception errors and coordinate-reference errors to misconstrue a weather balloon as a fast-maneuvering object must always be kept in mind. But in the Ft. Monmouth instance, as in many others that could be discussed in detail, there is a very large gap between the balloon hypothesis and the facts. The basic sighting-report here is quite similar to many other daytime sightings by airborne observers who have seen unconventional disc-like objects pass near their aircraft.

[[66]]

2. Case 32. Odessa, Wash., December 10, 1952 According to an official case-summary (Ref. 7, Rept 10), two airmen in an F94 “made visual and radar contact with a large, round white object larger than any known type of aircraft” near 1915 PST on 12/10/52 near Odessa. The radar operator in the F-94 had airborne radar contact with the object for 15 minutes, and during that same interval, ground radar was also tracking it. The summary states that “the object appeared to be level with the intercepting F-94 at 26,000 to 27,000 ft,” and it is pointed out that “a dim reddish-white light came from the object as it hovered, reversed direction almost instantaneously and then disappeared.” It is stated that the skies were clear above 3000 ft The official evaluation of this incident is “Possible Balloon”, although the report notes that no upper-air research balloon was known to be in the area on this date. The principal basis for calling it a balloon was the observers’ description of “large, round and white and extremely large”, and it was remarked that the instrument package on some balloon flights is capable of yielding a radar return. Discussion. — To conclude that this was a “Possible Balloon” just on the basis of the description, “large, round and white and extremely large”, and thereby to ignore the instantaneous course reversal and the inability of a 600-mph jet to close with it over a period of 15 minutes seems unreasonable. We may ignore questions of wind speeds at the altitude of the object and the F-94 because both would enjoy the same “tail-wind effect”. In 15 minutes, the F-94 would be capable of moving 150 miles relative to any balloon at its altitude. On the other hand, airborne radar sets of that period would scarcely detect a target of cross-section represented by the kinds of instrument packages hung on balloons of the Skyhook type, unless the aircraft were within something like 10 or 15 miles of it Yet it is stated that the F-94 was pursuing it under radar contact for a time interval corresponding to an airpath ten times that distance. Clearly, categorizing this unknown as a “balloon” was incompatible with the reported details of the case. On the other hand, there seems no reason to take seriously Menzel’s evaluation of this Odessa F-94 sighting (Ref. 25, p. 62). Menzel evidently had the full file on this case, for he adds a few details beyond those in Ref. 7, details similar to those in Ruppelt’s account of the case (Ref. 5) : “Dim reddish-white lights seemed to be coming from windows and no trail or exhaust was visible. The pilot attempted to intercept but the object performed amazing feats, did a chandelle in front of the plane, rushed away, stopped, and then made straight for the aircraft on a collision course at incredible speed.” He indicates that after the pilot banked to avoid collision he could not again locate it visually, although another brief radar contact was obtained. Having recounted those and other sighting details, Menzel then offers his interpretations: “In the east, Sirius was just rising over the horizon at the exact bearing of the unknown object. Atmospheric refraction would have produced exactly the phenomenon described. The same atmospheric conditions that caused the mirage of the star would have caused anomalous radar returns.” Now stars just above the viewer’s horizon do scintillate and do undergo turbulent image-displacement, but one must consider quantitative matters. A refractive excursion of a stellar image through even a few minutes of arc would be an extremely large excursion. To suggest that a pilot would report that Sirius did a chandelle is both to forget realities of astronomy and to do injustice to the pilot. In fact, however, Menzel seems to have done his computations incorrectly, for it is easily ascertained that Sirius was not even in the Washington skies at 7:15 p.m. PST on 12/10/52. It lay at about 10 degrees below the eastern horizon. A further quite unreasonable element of Menzel’s explanation of the Odessa case is his easy assertion that the radar returns were anomalous results of the “atmospheric conditions”. Aircraft flying at altitudes of 26,000 ft do not get ground returns on level flight as a result of propagation anomalies. These extreme forcings of explanations recur throughout Menzel’s writings; one of their common denominators is lack of attention to relevant quantitative factors. 3. Case 33. Rosalia, Wash.. February 6, 1953 Another official case-summary of interest here is cited by Menzel (Ref. 25, p. 46). Keyhoe (Ref. 4), who studied the case-file on it much earlier, gives similar information, though in less detail. A B-36, bound for Spokane was over Rosalia, Wash., at 1:13 a.m. when, as Menzel describes it,

[[67]]

“the pilot *** sighted a round white light below him, circling and rising at a speed estimated at 150 to 200 knots as it proceeded on a southeast course.” Menzel states that the B-36 “made a sharp descending turn toward the light, which was in view for a period of three to five minutes.” The light was blinking, and Keyhoe mentions that the blink-interval was estimated at about 2 seconds. Menzel concurs in the official evaluation of this as a “weather balloon”, noting that a pilot balloon had been released at Fairchild AFB at 1:00 a.m., and remarking that the “winds aloft at altitudes of 7,000 to 10,000 ft. were from the northwest with a speed of about fifty knots.” He says that “computations showed that the existing winds would have carried the balloon to the southeast, and it would have been over Rosalia, which is 12.5 nautical miles southeast of Fairchild, in about fifteen minutes.” In fact, Rosalia lies 33 statute miles SSE of Fairchild, or about twice as far as Menzel indicates. The net drift of the balloon cannot be deduced simply from the winds in the 7-10,000-ft. layer; and, in fact, an examination of the upper-wind data for that area on February 6 indicates that the winds at lower levels were blowing out of the southwest. The trajectory of the balloon would have taken it initially east-northeast, then east, and finally curving back to the southeast as it got up to near the 10,000-ft. levels. By that time, it would have been already east of Spokane, nowhere near Rosalia. The small light (candle or flashlight bulb) used on night pibal runs is almost invisible to the naked eye beyond a few miles’ distance. (A 1-candle source at 3,000 ft. is equivalent to a star of about the first magnitude. At 6 miles, then, one finds that the same source equals the luminosity of a sixth-magnitude star, the limit of human vision under the most favorable conditions. For a pilot, looking out of a cockpit with slight inside glare to spot a 1-candle source against a dark background would require that the source be only a few miles away.) At some 30 miles, the B-36 pilot could not have seen the small light on a balloon east of Spokane. Menzel states that “the balloon carried white running lights which accounted for the blinking described, and the circling climb of the UFO is typical of a balloon’s course” Neither inference is supportable. The light used on pilot balloons is a steady source; only if one were right above it, with its random swing causing intermittent occultation, would one ever perceive blinking. But then, flying at B-36 speeds, the pilot would have swept over the sector of perceptible occultation in only a matter of seconds. Yet here the pilot watched it for a reported 3-5 minutes. Furthermore, “circling climb” cannot be called “typical of a balloon’s course.” The balloon trajectory is controlled by the ambient wind shears and only with unusually strong directional shears would a pilot flying a straight course perceive a pilot balloon to be “circling.” In all, there appear to be so many serious difficulties with the balloon explanation for the Rosalia sighting that it is not possible to accept Menzel’s statement: “Thus all the evidence supports ATIC’s conclusion that the UFO was a weather balloon.” 4. Case 34. Boston, Mass., June 1, 1954 At 0930 EDST, a Paris-New York TWA Constellation was passing near Boston when the cockpit crew spotted “a large, white-colored disc-like object” overhead (Ref. 41). Capt. Charles J. Kratovil, copilot W. R. Davis, and flight engineer Harold Raney all watched it for a total time of 10 minutes as they flew on their own southwestward course to New York. They would occasionally lose it behind overlying clouds. Knowing that they were flying into headwinds, they concluded that it could not be any kind of balloon, so they radioed the Boston airport control tower, which informed him that jets were scrambled and saw the object, but could not close with it. After landing in New York, Capt. Kratovil was informed that official spokesmen had attributed the sighting to a “weather balloon” released from Grenier AFB, in New Hampshire.

[[68]]

Discussion. — I am still in the process of trying to locate Kratovil to confirm sighting details; but the fact that four newspaper accounts for that day give the same information about the major points probably justifies acceptance of those points. From upper-wind data for that area and time, I have confirmed the presence of fairly strong flow from the WSW aloft, whence Kratovil’s press comment, “If this was a weather balloon, it’s the first time I ever saw one traveling against the wind,” seems reasonable. The cruising speed of a Constellation is around 300 mph, so during the reported 10 minutes’ duration of the crew’s sighting, they moved about 50 miles relative to the air, so it would have been impossible for them to have kept a weather balloon in sight for this long. Furthermore, it was about 1.5 hours after scheduled balloon-release time, so that even a small balloon would have either burst or passed to altitudes too high to be visible. Finally, with flow out of the southwest sector from surface to above 20,000 ft., any balloon from Grenier AFB would have been carried along a trajectory nowhere near where the TWA crew spotted the “large, white-colored, disc-like object” overhead. 5. In my files are many other “balloon” cases from the past twenty years, cases that ought never have been so labeled, had the evaluators kept relevant quantitative points in mind. To ignore most of the salient features of a sighting in order to advance an easy “balloon” explanation is only one more of many different ways in which some very puzzling UFO observations have been shoved out of sight.

WHY AREN’T UFO’S EVER TRACKED BY RADAR?

The skeptic who asks this question, and many do, is asking a very reasonable question. With so much radar equipment deployed all over the world, and especially within the United States, it seems sensible to expect that, if there are any airborne devices maneuvering in our airspace, they ought to show up on radars once in a while. They do indeed, and have been doing so for all of the two decades that radar has been in widespread use. Here, as with so many other general misconceptions about the true state of the UFO problem, we encounter disturbingly large amounts of misinformation. As with other categories of UFO misinformation, the only adequate corrective is detailed discussion of large numbers of individual cases. Only space limitations preclude discussion of dozens of striking radar-tracking incidents involving UFOs, both here and abroad; they do exist. 1. Case 35. Fukuoka, Japan, October 15,1948. A very early radar-UFO case, still held as an official Unidentified, involved an attempted interception of the unknown object by an F-61 flying near Fukuoka, Japan, at about 11:00 p.m. local time on 10/15/48. The official file on this incident is lengthy (Ref. 42) ; only the highlights can be recounted here. The F-61 (with pilot and radar operator) made six attempts to close with the unknown, from which a radar return was repeatedly obtained with the airborne radar. Each time the radarman would get a contact and the F-61 pilot tried to close, the unknown would accelerate and pass out of range. Although the radar return seemed comparable to that of a conventional aircraft, “the radar observer estimated that on three of the sightings, the object traveled seven miles in approximately twenty seconds, giving a speed of approximately 1200 mph” In another passage, the official case-file remarks that “when the F61 approached within 12,000 feet, the target executed a 180° turn and dived under the F-61” adding that “the F-61 attempted to dive with the target but was unable to keep pace” The report mentions that the unknown “could go almost straight up or down out of radar elevation limits” and asserts further that “this aircraft seemed to be cognizant of the whereabouts of the F-61 at all times …” The F-61 airmen, 1st Lt. Oliver Hemphill (pilot) and 2d Lt. Barton Halter (radarman) are described in the report as being “of excellent character and intelligence and are trained observers.” Hemphill, drawing on his combat experience in the European theater, said that “the only aircraft I can compare our targets to is the German ME-163.”

[[69]]

The airmen felt obliged to consider the possibility that their six attempted intercepts involved more than one unknown. Hemphill mentions that, in the first attempted intercept, “the target put on a tremendous “burst of speed and dived so fast that we were unable to stay with it.” After this head-on intercept, Hemphill did a chandelle back to his original 6000-ft altitude and tried a stern interception, “but the aircraft immediately outdistanced us. The third target was spotted visually by myself,” Hemphill’s signed statement in the case-file continues. “I had an excellent silhouette of the target thrown against a very reflective undercast by a full moon. I realized at this time that it did not look like any type aircraft! was familiar with, so I immediately contacted my Ground Control Station …” which informed him there were no other known aircraft in the area. Hemphill’s statement adds further that, “The fourth target passed directly over my ship from stern to “bow at a speed of roughly twice that of my aircraft, 200 mph. I caught just a fleeting glance of the aircraft; just enough to know he had passed on. The fifth and sixth targets were attempted radar interceptions, but their high rate of speed put them immediately out of our range” (Note the non-committal terminology that treats each intercept target as if it might have been a separate object.) A sketch of what the object looked like when seen in silhouette against the moonlit cloud deck is contained in the file. It was estimated to be about the size of a fighter aircraft, but had neither discernible wings nor tail structures. It was somewhat bullet-shaped, tapered towards the rear, but with a square-cut aft end. It seemed to have “a dark or dull finish”. Discussion. — Ground radar stations never detected the unknown that was seen visually and contacted by airborne radar. The report indicates that this may have been due to effects of “ground, clutter”, though the F-61 was seen intermittently on the ground units. The airmen stated that no exhaust flames or trail were seen from this object with its “stubby, clean lines”. The total duration of the six attempted intercepts is given as 10 minutes. We deal here with one of many cases wherein radar detection of an unconventional object was supported by visual observation. That this is carried as Unidentified cannot surprise one; what is surprising is that so many other comparable instances are on record, yet have been ignored as indicators of some scientifically intriguing problem demanding intensive study. 2. Case 36. Nowra, Australia, September, 1954 The first UFO case to command general press attention in the Australian area seems to have been a combined radar-visual sighting wherein the pilot of a Hawker Seafury from Nowra Naval Air Station visually observed two unknown objects near him as he flew from Canberra to Nowra (Ref. 43). Press descriptions revealed only that the pilot said “the two strange aircraft resembling flying saucers” were capable of speeds much beyond his Seafury fighter. He saw them flying nearby and contacted Nowra radar to ask if they had him on their scope; they informed him that they had three separate returns, at which juncture he described the unidentified objects. Under instructions from the Nowra radar operator, he executed certain maneuvers to identify himself on the scope. This confirmed the scope-identity of his aircraft vs. the unknowns. As he executed the test maneuvers, the two unknowns moved away and disappeared. No explanation of this incident was offered by Naval authorities after it was widely reported in Australian and New Zealand papers about three months after it occurred. Discussion. — It is mildly amusing that the press accounts indicated that “the pilot, fearing that he might be ragged in the wardroom on his return if he abruptly reported flying saucers, called Nowra by radio and asked whether the radar screen showed his aircraft.” Only after getting word of three, not one, radar blips in his locality did he radio the information on the unknowns, whose configuration was not publicly released. This is in good accord with my own direct experience in interviewing Australian UFO witnesses in 1967; they are no more willing than Americans to be ridiculed for seeing something that is not supposed to exist. 3. Case 37. Capetown South Africa, May 23, 1953 In November 1958, the South African Air Force released a brief announcement concerning radar-tracking of six successive passes of one or more unknown high-speed

[[70]]

objects over the Cape. On January 1, 1967, in a transoceanic shortwave broadcast from South Africa, the authenticity of this report was confirmed, though no additional data beyond what had been cited earlier were presented. In the six passes, the target’s altitude varied between 5,000 and 15,000 ft, and its closest approach varied between 7 and 10 miles. Speeds were estimated at over 1200 mph, well beyond those of any aircraft operating in that area at that time. Discussion. — This report, on which the available information is slim, is cited to indicate that not only visual sightings but also radar sightings of seemingly unconventional objects appear to comprise a global phenomenon. By and large, foreign radar sightings are not readily accessible, and not easily cross-checked. Zigel (Ref. 88) briefly mentions a Russian incident in which both airborne and ground-based radar tracked an unidentified in the vicinity of Odessa, on April 4, 1966, the ground-based height-finding radar indicating altitudes of well over 100,000 ft. Such reports, without accessory information, are not readily evaluated, of course. 4. Case 38. Washington, D.C., July 19, 1952 By far the most famous single radar-visual sighting on record is the one which occurred late in the evening of July 19, and early on July 20, 1962, in the vicinity of Washington, D.C. (Refs. 2, 4, 5, 10, 24, 25). A curiously similar incident occurred just one week later. The official explanation centered around atmospheric effects on radar and light-propagation. Just before midnight on July 19/20, CAA radar showed a number of unidentified targets which varied in speed (up to about 800 mph) in a manner inconsistent with conventional aircraft A number of experienced CAA radarmen observed these returns, and, at one juncture, compatible returns were being received not only at the ARTC radar but also on the ARS radar in a separate location at Washington National Airport, and on still a third radar at Andrews AFB. Concurrently, both ground and airborne observers saw unidentifiable lights in locations matching those of the blips on the ground radar. Discussion. — I have interviewed five of the CAA personnel involved in this case and four of the commercial airline pilots involved, I have checked the radiosonde data against well-known radar propagation relations, and I have studied the CAA report subsequently published on this event Only an extremely lengthy discussion would suffice to present the serious objections to the official explanation that this complex sighting was a result of anomalous radar propagation and refractive anomalies of the mirage type. The refractive index gradient, even after making allowance for instrument lag, was far too low for “ducting” or “trapping” to occur; and, still more significant, the angular elevations of the visually observed unknowns lay far too high for radar-dueling under even the most extreme conditions that have ever been observed in the atmosphere. Some of the pilots, directed by ground radar to look for any airborne objects, saw them at altitudes well above their own flight altitudes, and these objects were maneuvering in wholly unconventional manner. One crew saw one of the unknown luminous objects shoot straight up, and simultaneously the object’s return disappeared from the ARTC scope being watched by the CAA radar operators. The official suggestion that the same weak (1.7° C) low-level “inversion” that was blamed for the radar ducting could produce miraging effects was quantitatively absurd, even if one overlooks the airline-pilot sightings and deals only with the reported ground-visual sightings. From the CAA radar operators I interviewed, as well as from the pilots I talked to about this case, I got the impression that the propagation-anomaly hypothesis struck them as quite out of the question, then and now. In fact, CAA senior controller Harry G. Barnes, who told me that the scope returns from the unknowns. “were not diffuse, shapeless blobs such as one gets from ground returns under anomalous propagation” but were strong, bright pips, said that “anomalous propagation never entered our heads as an explanation.” Howard S. Conklin, who, like Barnes, is still with FAA, was in the control tower that night, operating an entirely independent radar (short-range ARS radar). He told me that what impressed him about the sighting that night was that they were in radio communication with airlines crewmen who saw unidentified lights in the air in the same area as unknowns were showing up on his tower radar, while simultaneously he and Joseph Zacko were viewing the lights themselves from the tower at the D.C. Airport James M. Ritchey, who was at the ARTC radar with

[[71]]

Barnes and others, confirmed the important point that simultaneous radar fixes and pilot-sightings occurred several times that night He shared Barnes’ views that the experienced radar controllers on duty that night were not being fooled by ground returns in that July 19 incident. Among the airlines crewmen with whom I spoke about this event was S. C. Pierman, then flying for Capitol Airlines. He was one of the pilots directed by ground radar to search in a specific area for airborne objects. He observed high speed lights moving above his aircraft in directions and locations matching what the CAA radar personnel were describing to him by radio, as seen on their radars. Other airline personnel have given me similar corroborating statements. I am afraid it is difficult to accept the official explanations for the famous Washington National Airport sightings. 5. Case 39. Port Huron, Mich., July 29, 1952 Many of the radar cases for which sighting details are accessible date back to 1953 and preceding years. After 1953, official policies were changed, and it is not easy to secure good information on subsequent cases in most instances. A radar case in which both ground-radar and airborne-radar contact were involved occurred at about 9:40 p.m. CST on 7/29/52 (Refs. 4, 5, 7, 10, 25). From the official case summary (Ref. 7) one finds that the unknown was first detected by GGI radar at an Aircraft Control and Warning station in Michigan, and one of three F-94s doing intercept exercises nearby was vectored over towards it. It was initially coming in out of the north (Ref. 5, 25), at a speed put at over 600 mph. As the F-94 was observed on the GCI scope to approach the unknown, the latter suddenly executed a 180° turn, and headed back north. The F-94 was by then up to 21,000 ft., and the pilot spotted a brilliant multicolored light just as his radarman got a contact. The F-94 followed on a pursuit course for 20 minutes (Ref. 7) but could never close with the unknown as its continued on its northbound course. At the time of first radar lockon, the F-94 was 20 miles west of Pt. Huron, Mich. The GCI scope revealed the unknown to be changing speed erratically, and at one stage it was moving at a speed of over 14000 mph, according to Menzel (Ref. 25), who evidently drew his information from the official files. Ruppelt (Ref. 5) states that when the jet began to run low on fuel and turned back to its .base, GGI observed the unknown blip slow down, and shortly after it was lost from the GGI scope. Discussion. — This case is still carried as an official unknown. The case summary (Ref. 7) speculates briefly on whether it could have been “a series of coincident weather phenomena affecting the radar equipment and sightings of Capella, tut this is stretching probabilities too far.” Menzel, however, asserts that the pilot did see Capella, and that the airborne and ground radar returns “were merely phantom returns caused by weather conditions” No suggestion is offered as to how any given meteorological condition could jointly throw off radar at the ground and radar at 21,000 feet, no suggestion is offered to account for 180° course-reversal exhibited by the blip on the GCI scope just as the F-94 came near the unknown, no suggestion of how propagation anomalies could yield the impression of a blip moving systematically northward for 20 minutes (a distance of almost 100 miles, judging from reported F-94 speeds), with the F-94 return following along behind it. With such ad hoc explanations, one could explain away almost any kind of sighting, regardless of its content. I have examined the radiosonde sounding for stations near the site and time of this incident, and see nothing in them that would support Menzels interpretations. I have queried experienced military pilots and radar personnel, and none have heard of anything like “ground returns” from atmospheric conditions with aircraft radar operated in the middle troposphere. If Menzel is not considering ground-returns, in the several cases of this type which he explains away with a few remarks about “phantom radar returns”, then it is not clear what else he might be thinking of. One does have to have some solid target to get a radar return resembling that of an aircraft. Refractive anomalies of the “angel” type have very low radar cross-section and would not mislead experienced operators into confusing them with aircraft echoes. 6. Many other cases might be cited where UFOs have appeared on radar under conditions where no acceptable conventional explanation exists. Ref. 7 has a number of them. Hall (Ref. 10) lias about 60 instances in which both radar and visual sightings were involved. A December 19, 1964 case at Patuxent River NAS is one that I have checked on. It involved three successive passes of

[[72]]

an unknown moving at speeds estimated at about 7000 mph. It is an interesting case, one that came to light for somewhat curious reasons. A low overcast precluded any visual sightings from control tower personnel, so this is not a radar-visual case. I found no conventional explanation to account for it. It has to be stressed that there are many ways in which false returns can be seen on radarscopes, resulting not only from ducting of ground returns but also from interference from other nearby radars, from internal electronic signals within the radar set, from angels and insects (weak returns), etc. Hence each case has to be examined independently. After studying a number of official evaluations of radar UFO cases, I get the impression that there would probably be more radar Unknowns if there were less tendency to quickly explain them away by qualitative arguments that overlook pertinent quantitative matters. Even at that, there are too many conceded unknowns in official files to be ignored. A famous case in UFO annals involved a B-29 over the Gulf of Mexico, where several unknowns were tracked on the airborne scopes and were seen simultaneously by crewmen, moving under the aircraft as they passed by (Refs. 4, 10, 25). This one is still carried as Unidentified in official files. Still another famous combined radar-visual case, which Hynek has termed “one of the most puzzling cases I have studied,” occurred between Rapid City and Bismarck on August 5, 1953. It involved both ground and airborne radar and ground and airborne visual sightings, but is far too long and complex to recapitulate here. Perhaps the above suffices to indicate that UFOs are at times seen on radar and have been so seen for many years. The question of why we don’t hear a great deal about such sightings, especially with newer and more elaborate surveillance radars, is a reasonable question. Some of the answers to that one are posed by the statement of Dr. Robert M. L. Baker, Jr., in these proceedings. Other parts of the answer must be omitted here.

WHY AREN’T THERE NUMEROUS PHOTOS OF UFO’S IF THEY REALLY EXIST?

Here is a question for which I regard available answers as still unsatisfactory. I concede that it does seem reasonable to expect that there should, over the past 20 years, be substantially more good photos than are known to exist. Although I do not regard that puzzle as satisfactorily answered, neither do I think that it can be safely concluded that the paucity of good photos disproves the reality of the UFOs. Many imponderables enter into consideration of this question. 1. Some general considerations If one had reliable statistics on the fraction of the population that carried loaded cameras with them at any randomly selected moment (I would guess it would be only of the order of one per cent) and had figures bearing on the probability that a UFO witness would think of taking a photo before his observation terminated, then these might be combined with available information on numbers of sightings to attempt crude estimates of the expected number of UFO photos that should have accumulated in 20 years. Then one would need to weight the data for likelihood that any given photo would find its way to someone who would make it known in scientific circles, and then this figure might be compared with the very small number of photos that appear to stand the test of the exceedingly close scrutiny photos demand. A general rule among serious UFO investigators with whom I have been in touch is that the UFO photo is no better than the photographer (Hall). Many hoax photos have been brought forth. A UFO photo can be sold; this attracts hoax and fraud to an extent not matched in anecdotal accounts. Many photos have been clearly established as fraudulent in nature; far larger numbers seem so suspicious on circumstantial grounds that no serious investigator gives them more than casual attention. An interesting, even if very crude check on the likelihood of securing photos of UFOs from the general populace is afforded by fireball events. On April 25, 1966, a fireball, rated at about magnitude -10, arced northward across the northeastern U.S. From the total geographic area over which this fireball was visually detected, the population count is about 40 million persons. According to one account (Ref. 43), 200 visual accounts were turned in, and I infer that only 6 photos were submitted. The fireball was visible for a relatively long time as meteors go, about 80 seconds, and was, of course, at a great altitude (25 to 110 km). That 6 photos were submitted (at time of publication of the cited article)

[[73]]

from a potential population of sighters of 40 million might seem to argue that perhaps we really cannot expect to get many photos of UFOs. However, one of the principal reasons for citing the foregoing is to bring out the difficulties in drawing any firm conclusions. A phenomenon lasting 30 seconds scarcely permits the observer time to collect his wits and to swing into photographic action if he does have a loaded camera. UFO sightings have often extended over much longer than 30 seconds, by contrast, affording far better opportunity to think of snapping a photo. But, on the other hand, sighting a UFO in daytime at close range, judging from my own witness-interviewing experience, is a far more disconcerting and astonishing matter than viewing a brilliant meteor. Thus one can go back and forth, with so little assurance of meaningfulness of any of the relevant weight factors that the end result is not satisfactory. I simply do not know what to think about the paucity of good UFO photos, though I do feel uncomfortable about it. 2. Case 40. Corning, Calif., July 4, 1967 A case that may shed at least a bit of light on the paucity of photos involves a multiple-witness sighting near dawn at Corning, Calif., on 7/4/67. I have interviewed four witnesses who sighted the object from two separate locations involving lines of sight at roughly right angles, serving to confirm the location of the object as almost directly over Highway 5 just west of Corning. Jay Munger, proprietor of an all-night bowling alley, was having coffee with two police officers, Frank Rakes and James Overton, when he spotted the object through the front window of his place. All three rushed out to the parking lot to observe what they described as a large flattened sphere or possibly football-shaped object, with a brilliant light shining upward from the top and a dimmer light shining down from the underside. The dawn light was such that the object was visible by reflected light even though the object’s beams were discernible. It appeared at first to be hovering almost motionless at a few hundred feet above ground, and all three felt it lay about over Hwy. 5 (which estimate proved correct from sightings made on the highway by the independent witnesses). Their estimates of size varied from a diameter of maybe 50 feet to about 100 ft. It was silent, and the three men all emphasized to me that the quiet morning would have permitted hearing any kind of conventional aircraft engines. All three said they had never before seen anything like it. Munger decided to phone his wife to have her see the thing, and by the time he came back out from phoning, the object had moved southward along the highway by about a quarter of a mile or so. At about that juncture, it began to accelerate, and moved off almost horizontally, passing out of sight to the south in an additional time estimated at about 10-20 seconds. This case is relevant to the photo question since Officer Overton was on duty and had in his patrol car both binoculars and a loaded camera. When I asked him why he didn’t try to get a picture of the object, he admitted that he was so astonished by the object that he never even thought of dashing for the camera. I asked Munger to go through the motions that would yield a time estimate of the period he was inside phoning, to get a rough notion of how long Overton, along with Rakes, looked at it without thinking of the camera. The time was thus estimated by Munger as about a minute and a half, possibly two minutes. Discussion. — It may be hazardous to try to draw any conclusions from such a case, but I do think it suggests the uncertainty we face in trying to assess the likelihood of any given witness getting a photo of a UFO he happens to see. A colleague of mine at the University of Arizona was out photographing desert flowers on a day when a most unusual meteorological event occurred nearby – a tornado funnel came down from a cloud. Despite having the loaded camera at hand, despite having just been taking other pictures, and despite the great rarity of Arizona tornadoes, that colleague conceded that it wasn’t till much later that the thought of getting a photo rose to consciousness, by which time the funnel was long since dissipated. In the Trinidad, Colo. case of March 23, 1966 (Case 14 above), Mrs. Frank R. Hoch pointed out to me that she had loaded still and movie cameras inside the house, yet never thought about getting a photo. Again, the reason cited was the fascination with the objects being viewed. I think this “factor of astonishment” would have to be allowed for in any attempt to estimate expected numbers of photos, but I would be quite unsure of just how to evaluate the factor quantitatively.

[[74]]

3. Case 41. Edwards AFB, May 3, 1957 Occasionally, one could argue, UFOs ought to come into areas where there were persons engaged in photographic work, who were trained to react a bit faster, and who would secure some photos. One such instance evidently occurred at Edwards AFB on the morning of 5/3/57. I have managed to locate and interview three persons who saw the resultant photos. The two who observed the UFO and obtained a number of photos of it were James D. Bittick and John R. Gettys, Jr, both of whom I have interviewed. They were at the time Askania cameramen on the test range, and spotted the domed-disc UFO just as they reached Askania #4 site at Edwards, a bit before 8:00 a.m. that day. They immediately got into communication with the range director, Frank E. Baker, whom I have also interviewed, and they asked if anyone else was manning an Askania that could be used to get triangulation shots. Since no other camera operators were on duty at other sites, Baker told them to fire manually, and they got a number of shots before the object moved off into the distance. Bittick estimated that the object lay about a mile away when they got the first shot, though when first seen he put it at no more than 500 yards off. He and Gettys both said it had a golden color, looked somewhat like an inverted plate with a dome on top, and had square holes or panels around the dome. Gettys thought that the holes were circular not square. It was moving away from them, seemed to glow with its own luminosity, and had a hazy, indistinct halo around its rim, both mentioned. The number of shots taken is uncertain; Gettys thought perhaps 30. The object was lost from sight by the time it moved out to about five miles or so, and they did not .see it again. They drove into the base and processed the film immediately. All three of the men I interviewed emphasized that the shots taken at the closer range were very sharp, except for the hazy rim. They said the dome and the markings or openings showed in the photos. The photos were shortly taken by Base military authorities and were never seen again by the men. In a session later that day, Bittick and Carson were informed that they had seen a weather balloon distorted by the desert atmospheric effects, an interpretation that neither of them accepted since, as they stated to me, they saw weather ballons being released frequently there and knew what balloons looked like. Accounts got into local newspapers, as well as on wire services (Ref. 44). An Edwards spokesman was quoted in the Los Angeles Times as saying, “This desert air does crazy things,” An INS wire-story said, “intelligence officers at Edwards … would say almost nothing of the incident.” Discussion. — I have not seen the photos alleged to have been taken in this incident, I have only interviewed the two who say they took them and a third person who states that he inspected the prints in company with the two Askania operators and darkroom personnel. I sent all of the relevant information on this case to the University of Colorado UFO project, but no checks were made as a result of that, unless done very recently. It would be rather interesting to see the prints. 4. Photographic sky-survey cameras might be expected to get photos of UFOs from time to time. However, one finds that, in many sky-photography programs in astronomy, tracks that do not obviously conform to what is being sought, say meteor-tracks, are typically ignored as probable aircraft. Indeed, a very general pattern in all kinds of monitoring programs operates to bias the system against seeing anything but what it was built to see. Nunn-Baker satellite cameras are only operated when specific satellites are computed to be due overhead, and then the long axis of the field is aligned with the computed trajectory. Anything that crosses the field and leaves a record on the film with an orientation markedly different from the predicted trajectory is typically disregarded. Photographic, radar, and visual observing programs have a large degree of selectivity intentionally built into them in order not to be deluged with unwanted “signals”. Hence one must be rather carefnl in suggesting that our many tracking systems surely ought to detect UFOs. There’s much evidence to suggest that, if they did, the signal would be ignored as part of a systematic rejection of unwanted data. Even in the practices of the GOC (Ground Observer Corps), some units received instructions to report nothing but unidentified aircraft. (But, for examples of some UFOs that did get into the GOC net, see Hall, Ref. 10.) Although I am aware of a few photos allegedly showing UFOs, for which I have no reason at present to doubt the authenticity (for example a series of snapshots taken by a brother and sister near Melbourne, Australia, showing a somewhat indistinct disc in various positions), I must emphasize that the total

[[75]]

sample is tiny. Compared with that, I have seen dozens of alleged UFO photos which I regard as of dubious origin. Other UFO photos of which I am aware are still in process of being checked in one way or another. To summarize, I do have the impression that we ought to have more valid UFO photos than the small number of which I am aware.

IF UFO’S ARE REAL, SHOULDN’T THEY PRODUCE SOME REAL PHYSICAL EFFECTS?

Again, the answer is that they do. There are rather well-authenticated cases spanning a wide variety of “physical effects.” Car-stopping cases are one important class. UFOs have repeatedly been associated with ignition failures and light-failures of cars and trucks which came near UFOs or near which the UFOs moved. I would estimate that one could assemble a list of four or five dozen such instances from various parts of the world. Interference with radios and TV receptions have been reported many times in connection with UFO sightings. There are instances where UFOs have been reported as landing, and after departure, holes in the ground, or depressions in sod, or disturbed vegetation patterns have been described. In many such instance’s, the evident reliability of the witnesses is high, the likelihood of hoax or artifice small. A limited number of instances of residues left behind are on record, but these are not backed up by meaningful laboratory analyses, unfortunately. A physical effect that does not typically occur under conditions where the description of events might seem to call for it, relates to sonic booms. Although there are on record a few cases where fast-moving UFOs were accompanied by explosive sounds that might be associated with sonic booms, there are far more instances in which the reported velocity corresponded to supersonic speeds, yet no booms were reported. A small fraction of these can be rationalized by noting that the reporting witnesses were located back within the “Mach cone” of the departing UFO; but this will not suffice to explain away the difficulty. One feels that if UFOs are solid objects, capable of leaving depressions in soil or railroad ties when they land, and if they can dash out of sight in a few seconds (as has been repeatedly asserted by credible witnesses), they should produce sonic booms. This remains inexplicable; one can only lamely speculate that perhaps there are ways of eliminating sonic booms that we have not yet discovered; perhaps the answer involves some entirely different consideration. If we include among “physical effects” those that border on the physiological, then there appear to be many odd types. Repeatedly, tingling and numbness have been described by witnesses who were close to UFOs; in many instances outright paralysis of a UFO witness has occurred. These effects might, of course, be purely psychological, engendered by fear; but in some instances the witnesses seem to have noted these effects as the first indication that anything unusual was occurring. A number of instances of skin-reddening, skin-warming, and a few instances of burns of very unusual nature are on record. These physiological effects are sufficiently diverse that caution is required in attempting generalization. Curiously, a peculiar tingling and paralysis seem to be reported more widely than any other physiological effects. A person who is almost unaware of the ramifications of the UFO evidence may think it absurd to assert that people have been paralyzed in proximity to UFOs; the skeptic might find it inconceivable that such cases would go unnoticed in press and medical literature. Far from it, I regret to have to say, on the basis of my own investigations. I have encountered cases where severe bodily damage was done, or where evident hazard of damage was involved, yet the witness and his family found ridicule mounting so much faster than sympathy that it was regarded wiser to quietly forget the whole thing. At an early stage of my investigations I would have regarded that as quite unbelievable; UFO investigators with longer experience than mine will smile at that statement, but probably they will smile with a degree of understanding. I could cite specific illustrations to make all this much clearer, but will omit them for space-limitations, except for a few remarks in the next section.

IS THERE ANY EVIDENCE OF HAZARD OR HOSTILITY IN THE UFO PHENOMENA?

Official statements have emphasized, for the past two decades, that there is no evidence of hostility in the UFO phenomena. To a large degree, this same conclusion seems indicated in the body of evidence gathered by independent investigators. The related question as to potential hazard is perhaps less clear. There are on record a number of cases (I would say something like a few dozen cases) wherein persons whose reliability does not seem to come into serious

[[76]]

question have reported mild, or in a very few instances, substantial injury as the result of some action of an unidentified object. However, I know of only two cases for which I have done adequate personal investigation, in which I would feel obliged to describe the actions as “hostile”. That number is so tiny compared with the total number of good UFO reports of which I have knowledge that I would not cite “hostility” as a general characteristic of UFO phenomena. One may accidentally kick an anthill, killing many ants and destroying the ants’ entrance, without any prior “hostility” towards the ants. To walk accidentally into a whirling airplane propeller is fatal, yet the aircraft held no “hostility” to the unfortunate victim. In the UFO phenomena, we seem to confront a very large range of unexplained, unconventional phenomena and if among them we discern occasional instances of hazard, it would be premature to adjudge hostility. Yet, as long as we remain so abysmally ignorant of over-all nature of the UFO problem, it seems prudent to make all such judgments tentative. If UFOs are of extraterrestrial origin, we shall need to know far more than we now know before sound conclusions can be reached as to hazard-and-hostility matters. For-this reason alone, I believe it to be urgently important to accelerate serious studies of UFOs. In the remainder of this section, I shall briefly cite a number of types of cases that bear on questions of hazard: 1. Car-stopping cases In a two-hour period near midnight, November 2-3, 1957, nine different vehicles all exhibited ignition failures, and many suffered headlight failures as objects described as about 100-200 ft long, glowing with a general reddish or bluish glow, were encountered on roads in the vicinity of the small community of Levelland, Tex. (Ref. 10, 13, 14). This series of incidents became national headline news until officially explained in terms of ball lightning and wet ignitions. However, on checking weather data, I found that there were no thunderstorms anywhere close to Levelland that night, and there was no rain capable of wetting ignitions. Although I have not located any of the drivers involved, I have interviewed Sheriff Weir Clem of Levelland and a Levelland newspaperman, both of whom investigated the incidents that night. They confirmed the complete absence of rain or lightning activity. The incidents cannot be regarded as explained. This class of UFO effect is by no means rare. In France in the 1954 wave of UFO sightings, Michel (14) has described many such cases involving ignition-failure in motorbikes, cars, etc. Similar instances were encountered in my checks on Australian UFO cases. There are probably of the order of a hundred cases on record (see Ref. 10 for a list of some dozens). In only a very few cases has there been any permanent damage to the vehicle’s electrical system. In the Levelland case, for example, as soon as the luminous object receded from a given disturbed vehicle, its lights came back on automatically (in instances where the switches had been left on), and the engines were immediately restartable. The latter point in itself makes the “wet ignition” explanation unreasonable, of course. It is unclear how such effects might be produced. One suggestion that has been made as to ignition-failure is that very strong magnetic fields might so saturate the iron core of the coil that it would drive the operating point up onto the knee of the magnetization curve, so that the input magnetic oscillations would produce only very small output effects. Only a few oersteds would have to be produced right at the coil to accomplish this kind of effect, but when one back-calculates, allowing for shielding effects and typical distances, and assumes an inverse-third-power dipole field, the requisite H-values within a few feet of the “UFO dipole” end, to speak here somewhat loosely, come out in the megagauss range. Curiously, a number of other back-calculations of magnetic fields end up in this same range; but obviously terrestrial technologies would not easily yield such intensities. Clear evidence for residual magnetization that might be expected in the foregoing hypothesis does not exist, so far as I know. The actual mechanism may be quite unlike that mentioned. How lights are extinguished is even less clear, although, in some vehicles, relays in the lighting circuits might be magnetically closed. The lights pose more mystery than the ignition. Such cases do not constitute very disturbing questions of hazard or hostility. One might argue that highway accidents could be caused by lighting and ignition failures; however, more serious highway-accident dangers are implicit in other UFO cases where no electrical disturbance was caused. Many motorists have reported nearly losing control of vehicles when UFOs have swooped down over them; this hazard is distinctly more evident

[[77]]

than hazard from the car-stopping phenomenon. Indeed, the number of instances of what we might term “car-buzzing” instances that have involved road-accident hazards is large enough to be mildly disturbing, yet I know of no official recognition of this facet of the UFO problem either. An incident I learned of in Australia involved such fright on the part of the passengers of the “buzzed”’ vehicle that they jumped out of the car before it had come to a stop, and it went into a ditch. A similar instance occurred not long ago in the U.S. For reasons of space-limitations, I shall not cite other such cases, though it would not be difficult to assemble a list that would run to perhaps a few dozen. 2. Mild radiation exposure By “radiation” here, I do not mean exposure to radioactivity or to other nuclear radiations, but skin irritations comparable to sunburn, etc. I have interviewed a number of persons who have experienced skin-reddening from exposure to (visible) radiations near UFOs. Rene Gilham, of Merom. Indiana, watched a UFO hovering over his home-area on the evening of Nov. 6. 1957, and received mild skin-burns, for example. I found in speaking with him that the symptoms were gone in a matter of days, with no after-effects. The witnesses in a car-stopping incident at Loch Raven Dam, Md., on the night of Oct. 26, 1958, who were close to a brightly luminous, blimp-sized object after getting out of their stopped car, experienced skin-reddening for which they obtained medical attention. Without citing other such instances, I would say that these cases are not suggestive of any serious hazard, but they warrant scientific attention. 3. More serious physical injuries James Flynn, of Ft. Myers. Fla., in a case that has been rather well checked by both APRO and NICAP investigators, reportedly suffered unusual injuries and physical effects when he sought to check what he had taken to be a malfunctioning test vehicle from Cape Canaveral that had come down in the Everglades, Mar 15, 1965. I have spoken with Flynn and others who know him and believe that his case deserved much more than the superficial official attention it received when he reported it to proper authorities. He was hospitalized for about a week, treated for a deep hemorrhage of one eye (without medical evidence of any blow), and suffered loss of all of the principal deep-tendon reflexes for a number of days, according to his physician’s statement, published by APRO (Ref. 45). An instance of more than mere skin-reddening, associated with direct contact with a landed unidentified object, reportedly occurred in Hamilton, Ontario, March 29, 1966. Charles Cozens, then age 13, stated to police and to reporters (and recounted to me in a telephone interview with him and his father) that he had seen two rather small whitish, luminous objects come down in an open field in Hamilton that evening. He moved towards them out of curiosity, and states that he finally moved right up beside them, and touched the surface of one of them to see what it felt like. It was not hot, and seemed unusually smooth. One of the two small (8 ft by 4 ft plan form, 3-4 feet high) bun-shaped objects had a projection on one end that the boy thought might have been some kind of antenna, so he touched it. only to have his hand flung back as a spark shot out from the end of the projection into the air. He ran, thinking first to go to a nearby police substation. But on looking over his shoulder after getting to the edge of the field and seeing no objects there, he decided the police might not believe him and ran to his home. His parents, after discussing the incident at some length with the frightened boy, notified police, which is how the incident became public knowledge. Two others in Hamilton saw that night seemingly similar objects, but airborne rather than on the ground. Cozens was treated for a burn or sear on the hand that had been in contact with the projection at the moment the spark was emitted. On questioning both the boy and his father, I was left with the impression that, despite the unusual nature of the report, it was described with both straightforwardness and concern and that it must be given serious consideration. Clearly one would prefer a number of adult witnesses to an individual boy; yet I believe the case will stand close scrutiny. There are a few other such reports of moderate injury reportedly sustained in direct physical contact with landed aerial objects for which I do not set feel satisfied with the available degree of authentication. It would be very desirable to conduct far more thorough investigations of some foreign cases of this type, to check the weight of the evidence involved. That only a very small number of such cases is on record should be emphasized.

[[78]]

4. Rare instances suggesting overt hostility In my own investigative experience, I know of only two cases of injuries suffered under what might be describable as overt hostility, and for which present evidence argues authenticity. There are other reports on record that might be construed as overt hostility, but I cannot vouch for them in terms of my own personal investigations. In Beallsville, Ohio, on the evening of March 19, 1968, a boy suffered moderate skin burns in an incident of puzzling nature. Gregory Wells had just stepped out of his grandmother’s house to walk a few tens of yards to his parents’ trailer when his grandmother and mother heard his screams, ran out and found him rolling on the ground, his jacket burning. After being treated at a nearby hospital, he described to parents, sheriff’s deputies, and others what he had seen. Hovering over some trees across the highway from his location, he had seen an oval-shaped object with some lights on it. From a central area of the bottom, a tube-like a endage emerged, rotated around, and emitted a flash that coincided with ignition of his jacket. He had just turned away from it and so the burn was on the back of his upper arm. In the course of checking this case, I interviewed a number of persons in the Beallsville area, some of whom had seen a long cylindrical object moving at very low altitude in the vicinity of the Wells’ property that night. There is much more detail than can be recapitulated here. My conversations with persons who know the boy, including his teacher, suggest no reason to discount the story, despite its unusual content. After checking the Beallsville incident, I checked another report in which burn-injuries of a more serious nature were sustained in a context even more strongly indicative of overt hostility. I prefer not to give names and explicit citation of details here, but I remark that there appears to me, on the basis of my present information and five interviews with persons involved, to be basis for accepting the incident as real. Partly because of its unparalleled nature, and partly because some of the evidence is still conflicting, I shall omit details and state only that the case, taken together with other scattered reports of injuries in UFO encounters, warrants no panic response but does warrant far more thorough investigation than any that has been conducted to date. 5. UFOs and other electromagnetic disturbances There are so many instances in which close-passage of an unidentifled flying object led to radio and television disturbance that this particular mode of electromagnetic effect of UFOs seems incontrovertible. One would require nothing mor than broad-spectrum electromagnetic noise to account for these instances, of course. There is a much smaller number of instances, some of which I have checked. in which power has failed only within an individual home coincident with nearby passage of a UFO. Magnetic saturation of the core of a transformer might conceivably account for this phenomenon. Then there are scattered instances in which substantial power distribution systems have failed at or very near the time of observation of aerial phenomena similar, broadly speaking, to one or another UFO phenomenon. I have personally checked on several such instances and am satisfied that the coincidence of UFO observation and power outage did at least occur. Whether there is a casual connection here, and in which direction it may run, remains quite uncertain. Even during the large Northeast blackout, November 9, 1965, there were many UFO observations, several of which I have personally checked. I have inquired at the Federal Power Commission to secure data that might illuminate the basic question of whether these are merely fortuitous, but the data available are inadequate to permit any definite conclusions. In other parts of the world, there have also been reports of system outages coincident with UFO sightings. Again, the evidence is quite unclear as to casual relations. There is perhaps enough evidence pointing towards strong magnetic fields around at least some UFOs that one might hypothesize a mechanism whereby a UFO might inadvertently trigger a power outage. Perhaps a UFO, with an accompanying strong magnetic field, might pass at high speed across the conductors of a transmission line, induce asymmetric current surges of high transient intensity, and thereby trip circuit breakers and similar surge-protectors in such a way as to initiate the outage. There are some difficulties with that hypothesis, of course; but it could conceivably bear some relation to what has reportedly occurred in some instances.

[[79]]

I believe that the evidence is uncertain enough that one can only urge that competent scientists and engineers armed both with substantial information on UFO phenomena and with relevant information on power-system electrical engineering, ought to be taking a very close look at this problem. I am unaware of any adequate study of this potentially important problem. Note that a problem, a hazard, could exist in this context without anything warranting the label of hostility.

MISAPPLICATIONS OF ATMOSPHERIC PHYSICS IN PAST UFO EXPLANATIONS

1. General comments Since the bulk of UFO reports involve objects reportedly seen in the air, it is not surprising that many attempts to account for them have invoked principles of atmospheric physics. Over the past twenty years, many of the official explanations of important UFO sightings have been based on the premise that observers were misidentifying or misinterpreting natural atmospheric phenomena. Dr. D. H. Menzel, former director of Harvard Observatory, in two books on UFOs (Ref. 24, 25), has leaned very heavily on atmospheric physics and particularly meteorological optics in attempting to account for UFO reports. More recently, Mr. Philip J. Klass, Senior Avionics Editor of Aviation Week, has written a book (Ref.36) purporting to show that most of the really interesting UFO reports are a result of unusual atmospheric plasmas similar to ball lightning. Over the years, many others have made similar suggestions that the final explanation of the UFOs will involve some still not fully understood phenomenon of atmospheric physics. As a scientist primarily concerned with the field of atmospheric physics, these suggestions have received a great deal of my attention. It is true that a very small fraction of all of the raw reports involve misidentified atmospheric phenomena. It is also true that many lay observers seriously misconstrue astronomical (especially meteoric) phenomena as UFOs. But, in my opinion, as has been emphasized above and will be elaborated below, we cannot explain-away UFOs on either meteorological or astronomical grounds. To make this point somewhat clearer, I shall, in the following, remark on certain past attempts to base UFO explanations on meteorological optics, atmospheric electricity, and radar propagation anomalies. 2. Meteorological optical explanation Mirages, sundogs, undersuns, and various reflection and refraction phenomena associated with ice crystals, inversions, haze layers, and clouds have been invoked from time to time in an attempt to account for UFO observations. From my study of the past history of the UFO problem and from an examination of recent ”re-evaluations” of official UFO explanations, I have the strong impression that many alterations of explanations for classic UFO cases that have been made in the official files in the last few years reflect the response to the writings of Menzel (especially Ref. 25). I have elsewhere (Ref. 2) discussed a number of specific examples of what I regard as unreasonable applications of meteorological optics in Menzel’s writings. Some salient points will be summarized here. A principal difficulty with Menzel’s mirage explanations is that he typically overlooks completely stringent quantitative restrictions on the angle of elevation of the observer’s line of sight in mirage effects. Mirage phenomena are quite common on the Arizona desert, but both observation and optical theory are in good accord in showing that mirage effects are confined to lines of sight that do not depart from the horizontal by much more than a few tens of minutes of arc. Under some extremely unusual temperature conditions in the atmosphere (high latitude regions, for example), one may get miraging at elevation angles larger than a degree, but these situations are extremely rare, it must be emphasized. In Menzel’s explanations and in certain of the official explanations, however, mirages are invoked to account for UFOs when the observer’s line of sight may depart from the horizontal by as much as five to ten degrees or even more. I emphasize that this is entirely unreasonable. If it were the case that all UFOs were reported essentially at the observer’s horizon, then one would have to be extremely suspicious that we were dealing with some unusual refraction anomalies. However, as has been shown by many cases cited above and has been long known to serious investigators of UFO phenomena, no fixed correlation exists. Some of the most interesting UFOs have been seen at close range directly overhead, quite obviously ruling out mirage explanations. The 1947 sighting by Arnold near Mt. Rainier is explained officially and by Menzel as a mirage,

[[80]]

yet the objects which he saw (nine fluttering discs) changed angular elevation, moved across his view through an azimuthal range of about 90 degrees, and were seen by him during the period when he was climbing his own plane through an altitude interval that he estimates to be of the order of 500 to 1000 ft. Anyone familiar with mirage optics would find it utterly unreasonable to claim that such an observation was satisfactorily explained as a mirage. Similarly, as has been noted above, the 1948 sighting by Eastern Airlines pilots Chiles and Whitted, once explained by Menzel as a “mirage”, involves quantitative and observational factors that are not even approximately similar to known mirage effects. There are some extremely rare and still not well-explained refractive anomalies in the atmosphere, such as those that have been discussed by Minnaert, but good UFO observations are so much more numerous than those types of rare anomalies that it is quite out of the question of explain the former by the latter. Sundogs, or parhelia, are a quite well-understood phenomenon of meteorological optics. Retractions of the sun’s rays on horizontally falling tabular ice crystals produce fuzzy, brownish-colored luminous spots at about 22 degrees to the left and right of the sun when suitable ice-crystal clouds are present. Rarer phenomena, produced by the moon rather than the sun, are termed paraselenae. Sundogs are relatively common, but it is probably true that many laymen are not really conscious of them as a distinct optical phenomenon. For this reason, it might seem sensible to suggest that some observers have been misled by thinking that sundogs were UFOs. However, anyone with the slightest knowledge of meteorological optics talking directly to such a witness would, within only a few moments of questioning, establish what was involved. Instead of dealing with anything like a sharp-edged “object”, one would quickly find that the observer was describing a very vague spot of light which he saw to the left or right of the sun, probably very near the horizon. To blandly suggest, as Menzel has done, that Waldo Harris in the 10/2/61 sighting near Salt Lake City was fooled by a sundog is to ignore either all of the main features of the report or to ignore all of what is known about sundogs. Undersuns, sub-suns, can be seen rather frequently when flying in jet aircraft at high altitudes. They are a reflection phenomenon produced by horizontally floating ice crystals, which reflect an image of the sun (or at night the moon) and can give surprisingly sharp solar images in still air where turbulence does not cause appreciable tilting of the ice crystals. Here again, it is probably true that many laymen may be sufficiently unaware of this optical phenomenon that they could be confused when they see one. But, as with sundogs, the stringent quantitative requirements on the location of this optical effect relative to the sun would permit any experienced investigator to quickly ascertain whether or not an undersun was involved in this specific sighting. The effect involves specular reflection of the sun’s rays, whence the undersun is always seen at a negative angle of elevation in which the observer’s line of sight to the undersun is just as far below the horizon as the sun momentarily lies above that same observer’s horizon. Clearly, many of the UFO cases that have been cited in examples given above do not come anywhere near satisfying the angular requirements for an undersun. In my own experience, I have already come across two or three reports, out of thousands that I have examined, where I was led to suspect that the observer was fooled by an undersun. “Reflections off clouds” have been referred to repeatedly in Menzel’s writings, never with any quantitative discussion of precisely what he means. But the impression is clearly left that many observers have been and are continuing to be fooled by some kind of cloud-reflections. Aside from the above-described undersun, I am unaware of any “cloud-reflection phenomenon” that could produce anything remotely resembling a distinct object. Clouds of droplets or ice crystals do not provide a source of specular reflection (except in the case of horizontally-floating ice crystals observed from above with a bright luminary, such as sun or moon, in the distance, undersun). What Menzel could possibly have in mind when he talks loosely about such cloud reflections (and he does so in many different places in his books), I cannot imagine. Inversions are invoked by Menzel, and in official evaluations, to account for certain UFO sightings. Inversions produced by radiational cooling or by atmospheric subsidence are relatively common meteorological phenomena. In some cases, quite sharp inversions with marked temperature differences in rather small vertical distances are known to occur. It is such inversion layers that are responsible for some of the most striking desert mirages of the looming type.

[[81]]

To experience a looming mirage, the observer’s eye must be located in the atmospheric layer wherein the temperature anomalously increases with height (inversion layer), and the miraged target in the object-field must also lie in or near the inversion layer. Inversion layers are essentially horizontally, and the actually-encountered values of the inversion lapse rates are such that refraction anomalies are confined to very small departures from the horizontal, as noted above under remarks on mirages. All of these points are well-understood principles of meteorological optics. However, Menzel has attempted to account for such UFOs as Dr. Clyde Tombaugh saw overhead at Las Cruces in August 1949 in terms of “inversion” refraction or reflection effects. Since I have discussed the quantitative unreasonableness of this contention elsewhere, I will not here elaborate the point, except to say that if inversions were capable of producing the optical disturbances that Menzel has assumed, astronomers would long since have given up any attempt to study the stars by looking at them through our atmosphere. Other atmospheric-optical anomalies have been adduced by Menzel in his UFO discussions. He has repeatedly suggested that layers of haze or mist cause remarkable enlargement of the apparent images of stars and planets. By enlargement, he makes very clear that he means radial enlargements in all directions such that the eye sees not a vertical streak of the sort well-known to astronomers as resulting from near-horizon refraction effects, but rather a circular image of very large angular size. Menzel even describes a sighting that he himself made, over Arctic regions in an Air Force aircraft, in which the image of Sirius was enlarged to an angular size of over ten minutes of arc (one-third of lunar diameter). I have discussed that sighting with a number of astronomers, and not one is aware of anything that has ever been seen by any astronomer that approximates such an instance. In fact, it would require such a peculiar axially-symmetric distribution of refractive index, which miraculously followed the speeding aircraft along as it moved through the atmosphere, that it seems quite hopeless to explain what Menzel has reported seeing in terms of refraction effects. Since Dr. Menzel’s writings on UFO’s have evidently had, in some quarters, a marked effect on attitudes towards UFOs, I regard that effect as deleterious. If I felt that we were dealing here with just a slight difference of opinion about rather controversial scientific matters on the edge of present knowledge. I would withhold strong comment. However, I wish to say for the record, that I reward the majority of Dr. Menzels purported meteorological-optical UFO explanations as simply scientifically incorrect. I could, but shall not here, enlarge upon similar critique of official explanations that have invoked such arguments. 3. Atmospheric electricity One phenomenon in the area of atmospheric electricity to which appeal has been made from the earliest years of investigations of the UFO phenomena is that of ball lightning. For example, a fairly extensive discussion of ball lightning was prepared by the U.S. Weather Bureau for inclusion in the 1949 Project Grudge report (Ref. 6). It was concluded in that report that ball lightning was most unlikely as an explanation for any of the cases which were considered in that report (about 250). Periodically, in succeeding years, one or another writer has come up with that same idea that maybe people who report UFOs are really seeing ball lightning. No one ever tried to pursue this idea very far, until P. J. Klass began writing on it. Although his ideas have received some attention in magazines, there is little enough scientific backup to his contentions that they are quite unlikely to have the same measure of effect that Menzel’s previous writings have had. For that reason, I shall not here elaborate on my strong objections to Klass’ arguments. I spelled them out in considerable detail in a talk presented last March at a UFO Symposium in Montreal held by the Canadian Aeronautics and Space Institute. Klass has ignored most of what is known about ball lightning and most of what is known about plasmas and also most of what is known about interesting UFOs in developing his curious thesis. It cannot be regarded as a scientifically significant contribution to illumination of the UFO problem. 4. Radar propagation anomalies In the past twenty years, there have been many instances in which unidentified objects have been tracked on radar, many of them with concurrent visual observations. Some examples have been cited above. It is always necessary to approach a radar unidentified with full knowledge of the numerous ways in which false returns can be produced on radar sets. The physics of “ducting”

[[82]]

or “trapping” is generally quite well understood. As with mirages, the allowed angle of elevation of the radar beam can only depart from zero by a few tens of minutes of arc for typically occurring inversions and humidity gradients. Ducting with beam angles in excess of a degree or so would require unheard of atmospheric temperature or humidity gradients. Care must be taken in interpreting that statement, since beam-angles have to be distinguished from angles of elevation of the beam axis. For the latter reason, a beam-axis elevation of, say, two degrees still involves emission of some radar energy at angles so low that some may be trapped, yielding “ground returns” despite the higher elevation of the axis. All such points are well described in an extensive literature of radar propagation physics. In addition to trapping and ground return effects, spurious returns can come from insects, birds, and atmospheric refractive-index anomalies that generate radar echoes termed “angels”. These are low-intensity returns that no experienced operator would be likely to confuse with the strong return from an aircraft or ther large metallic object. Also, other peculiar radar effects such as interference with other nearby sets, forward scatter from weak tropospheric discontinuities (see work of Atlas and others), and odd secondary reflections from ground targets need to be kept in mind. When one analyzes some of the famous radar-tracking cases in the UFO literature, none of these propagation anomalies seem typical as accounting for the more interesting cases. (Several examples have already been discussed. (cases 32, 35, 36, 37, 38, and 39).)

SUMMARY AND RECOMMENDATIONS

In summary, I wish to emphasize that my own study of the UFO problem has convinced me that we must rapidly escalate serious scientific attention to this extraordinarily intriguing puzzle. I believe that the scientific community has been seriously misinformed for twenty years about the potential importance of UFOs. I do not wish here to elaborate on my own interpretation of the history behind that long period of misinformation; I only wish to urge the Committee on Science and Astronautics to take whatever steps are within their power to alter this situation without further delay. The present Symposium is an excellent step in the latter direction. I strongly urge your Committee that further efforts in the same direction be made in the near future. I believe that extensive hearings before your Committee, as well as before other Congressional committees having concern with this problem, are needed. The possibility that the Earth might be under surveillance by some high civilization in command of a technology far beyond ours must not be overlooked in weighing the UFO problem. I am one of those who lean strongly towards the extraterrestrial hypothesis. I arrived at that point by a process of elimination of other alternative hypotheses, not by arguments based on what I could call “irrefutable proof.” I am convinced that the recurrent observations by reliable citizens here and abroad over the past twenty years cannot be brushed aside as nonsense, but rather need to be taken extremely seriously as evidence that some phenomenon is going on which we simply do not understand. Although there is no current basis for concluding that hostility and grave hazard lie behind the UFO phenomenology, we cannot be entirely sure of that. For all of these reasons, greatly expanded scientific and public attention to the UFO problem is urgently needed. The proposal that serious attention be given to the hypothesis of an extraterrestrial origin of UFOs raises many intriguing questions, only a few of which can be discussed meaningfully. A very standard question of skepticism is “Why no contact?” Here, the best answer is merely a cautionary remark that one would certainly be unjustified in extrapolating all human motives and reasons to any other intelligent civilization. It is conceivable that an avoidance of premature contact would be one of the characteristic features of surveillance of a less advanced civilization; other conceivable rationales can be suggested. All are speculative, however; what is urgently needed is a far more vigorous scientific investigation of the full spectrum of UFO phenomena, and the House Committee on Science and Astronautics could perform a very significant service by taking steps aimed in that direction.

(The biography of Dr. Sagan follows:)

DR. CARL SAGAN

Dr. Carl Sagan is Associate Professor of Astronomy in the Center for Radiophysics and Space Research at Cornell University, Ithaca, New York. He received his A.B. and B.S., an M.S. in Physics and his Ph.D. in Astronomy and Astrophysics, all from the University of Chicago. Since then he has held positions at the University of California, Berkeley; at Stanford University Medical School (as Assistant Professor of Genetics); and at Harvard University and the Smithsonian Astrophysical Observatory. Dr. Sagan’s major research interests are on the physics and chemistry of planetary atmospheres and surfaces, the origin of life on earth, and exobiology. He has played a leading role in establishing, for example, that the surface of Venus is very hot and that major elevation differences exist on Mars, and has been a principal exponent of the view that organic molecules are to be found on Jupiter. Dr. Sagan has served on many advisory groups to the National Aeronautics and Space Administration and to the National Academy of Sciences, as well as such international organizations as COSPAR and the International Astronomical Union. He was a member of the Committee to review Project Blue Book for the Air Force Scientific Advisory Board. A winner of the Smith Prize at Harvard in 1964 and Condon Lecturer in the State of Oregon in 1968, Dr. Sagan is shortly to assume additional duties as Editor of the planetary sciences journal, ICARUS. He has been active in educational innovations, regularly teaches in the South, and is a lecturer in the astronaut training program in Houston.

[[85]]

In addition to well over a hundred scientific papers, and several articles written or the Encyclopedias Britannica and Americana, Dr. Sagan is co-author of “The Atmospheres of Mars and Venus” (1961), “Planets” (1966), and “Intelligent Life in the Universe.” (1966).

STATEMENT OF DR. CARL SAGAN, DEPARTMENT OF ASTRONOMY, CORNELL UNIVERSITY, ITHACA, N.Y.

Dr. Sagan. Thank you very much, Congressman Roush. As I understand what the committee would like from me, is a discussion of the likelihood of intelligent extraterrestrial life, and since this estimate is to be made in this symposium, clearly it is the hypothesis that unidentified objects are of extraterrestrial origin which the committee must have in mind. I’m delighted to tell about contemporary scientific thinking along these lines, but let me begin by saying that I do not think the evidence is at all persuasive, that UFO’s are of intelligent extraterrestrial origin, nor do I think the evidence is convincing that no UFO’s are of intelligent extraterrestrial origin. I think as each of the preceding speakers has mentioned, but perhaps not sufficiently emphasized, that the question is very much an open one, and it is certainly too soon to harden attitudes and make any permanent contentions on the subject. I find that the discussion, like elsewhere, is best evaluated if we consider the question of life on earth. I suppose that if you had all your prejudices removed and were concerned with the question of whether the earth was populated by life of any sort, how would you go about finding out? If, for example, we were on some other planet, let’s say Mars, and looking at the Earth, what would we see? Fortunately we now have meteorological satellite photographs of the earth at various resolutions, so we can answer the question. The first large slide. This is a photograph of the earth. That is the full earth, which you are looking at which is primarily cloud cover. This is the Pacific Ocean. You can see southern California in the upper right, and, as advertised by the local chamber of commerce, you can see it is cloud free. [Laughter.] Dr. Sagan. Now, it is clear that very little information about the earth, much less possibility of life on it, is obtained by a picture at this resolution. The next large slide is a TIROS photograph of the earth at about 1-mile resolution, that is, things smaller than a mile cannot be seen, and very prolonged scrutiny of the entire eastern seaboard of the United States shows no sign of life, intelligent, or otherwise. We have looked at several thousand photographs of the earth, and you may be interested to see that there is no sign of life, not only in New York or Washington, but also in Peking, Moscow, London, Paris, and so on. The reason is that human beings have transformed the earth at this kind of scale very little, and therefore the artifacts of human intelligence are just not detectable photographically in the daytime with this sort of resolution. The next slide shows one of the few successful finds of intelligent life on earth that we made; down toward the lower left you can see

[[86]]

a kind of grid, a kind of crisscross pattern, a rectangular area. This is a photograph taken near Cochran, Ontario, in Canada. What we are looking at are swaths cut by loggers through the forest. They cut many swaths in parallel, then another parallel sequence of swaths at right angles. Then the snow fell, heightening contrast, so that is the reason for the tic-tac-toe pattern. The sequence of straight lines there is anomalous. You would not expect it by geological processes. If you found that on another planet you would begin to expect there is life there. This is a photograph at about a tenth of a mile resolution, and is far better than the best photographs we have of Mars. The photographs we have of Mars are, of course, better than of any other planet. Therefore, to exclude intelligent life on another planet photographically is certainly premature. We could not exclude life on earth with this same sort of resolution. However, there are other reasons why intelligent life on the other planets of this solar system are moderately unlikely. To continue this sequence of photographs, I should say there are only about one in a thousand photographs where this resolution of the earth gives any sign of life. The next photograph, however, shows a resolution about three times better. That is a Gemini capsule in the lower left-hand corner and we are looking at the vicinity of the Imperial Valley in California. You are just on the verge of resolving the contour patterns of fields, for agricultural purposes. The next slide shows us an area between Sacramento and San Francisco, which has a very clear geometric pattern. It is quite obvious that this is the result of some intelligent activity on the earth. You can see an airport, a railway, the monotonous pattern of housing developments in the upper right. You can see the patterns of contour fields. And this is such a highly geometrized picture, that it is clearly the result of some intelligence. However, a photograph taken of this same area, only let’s say 100,000 years ago, when there certainly was lots of life on earth, would show none of these features, because these are all the signs of our present technical civilization. So even though the earth was full of life, and human beings were very much in evidence 100,000 years ago, none of this would be detectable by such photography. To detect individual organisms on earth, we have to have a photographic resolution about 10 times better than this, then we occasionally see things like these in the next slide. All those little dots casting shadows are cows in a field in California. There are other ways of detecting intelligent life on the earth. From the vantage point of Mars, detecting, say, the lights of cities at night, is extremely marginal, and in fact the only way of doing it would be to point a small radio telescope at the earth, and then as the North American Continent turned toward Mars, there would be this blast of radio emission from domestic television transmission that prolonged scrutiny would indicate some sign of intelligent life on the earth. In fact, it is radio communications which is the only reasonable method of communications over very large distances. It is a remarkable fact that the largest radio telescope on the earth at the present time, the Arecibo dish in Puerto Rico, is capable of communicating

[[87]]

with another dish, similarly outfitted if one existed at the incredible distance of 1,000 light years away, a light year being about 6.6 trillion miles, and the distance to the nearest star being a little over 4 light years. Now, let me then go to the question of the cosmic perspective of where we are. We are, of course, sitting on a planet, the third from the Sun, which is going around the Sun, which is a star-like, and the other stars visible on a clear night to the naked eye. The first small slide will give an impression of what happens when you point a moderate telescope in the direction of the center of the Milky Way Galaxy. This is a photograph of a star cloud. You are looking at tens of thousands of suns here. In fact, the number of suns in our galaxy is about 150,000 million. They are collected into a disk-shaped pattern, shown in the next slide; the next slide will show a photograph of the nearest galaxy like our own. That fuzzy spiral thing in the middle is M-31, that is also known as the Great Galaxy Andromeda, and if that were a photograph of our galaxy, we would be situated extremely far out, in fact, a little far off the slide, very much in the galactic boon docks. The Sun is nowhere near the center of the galaxy. It is a very out-of-the-way rural location we happen to be in. Now, in [the] collection of 150,000 million stars in the Milky Way Galaxy, our sun is just one, and there are at least billions of other galaxies, and the last slide, will show you what happens if you point a telescope away from the obscuring dust and stars in the galaxy. You then start seeing dozens of other galaxies, everyone of those funny-shaped spiral and irregular-shaped things there, and some of the spherical-shaped ones, are other galaxies, each of which are containing about 100 billion stars as well. So it is clear that there are in the accessible universe, some hundreds of billions of billions of stars, all more or less like our own. Now, if we want to assess the likelihood that there are intelligent civilizations somewhere in advance of our own, on planets of other stars in our own galaxy, we have to ask questions which cover a variety of scientific subjects, some of which are fairly well known, some of which are extremely poorly known. For a numerical assessment of whether there is likely intelligence in other parts of the galaxy in a form we do not have at present, let me indicate the kinds of things we know. It depends on the rate of star formation. It depends on the likelihood that the given star has planets. It depends on the likelihood at least one of those planets is at a position from the essential star which is suitable for the origin of life. It depends on the likelihood that the origin of life actually occurs on that planet. It depends on the probability life once arisen on that planet will evolve to some intelligence. It depends on the likelihood that intelligence, once emerged, will develop a technical civilization. And it depends on the lifetime of the technical civilization, because technical civilization of a very short lifetime, will result in very few technical civilizations being around at any given time. We know something about some of these. There is some reason to believe that planets are a reasonable

[[88]]

likely accompaniment of star formation, that the solar system in other words is a fairly common event in the galaxy and is not unique. There are laboratory experiments on the origin of life, in which the early conditions on earth have been duplicated in the laboratory. It turns out that at least the molecules fundamental to living systems, are produced relatively easy [sic], physics and chemistry apparently made in such a way that the origin of life may be a likely event. Beyond that it is difficult to do laboratory experiments, because evolution takes billions of years, and scientists aren’t that patient. Therefore, it is just a question of intelligent and knowledgeable estimates. Here, some scientists believe that the evolution of intelligence and technical civilization is very likely. Others believe it is a very remarkable and unusual event and by the merest fluke did it happen here. I don’t think that this is the place to go into this very difficult question in any great detail. Let me merely say that much more important than these uncertainties is the question of the life of a technical civilization, judging from the events on the earth, one might say the likelihood of our civilization lasting only a few decades more, might be a fairly high probability, and if that is typical of other civilizations, then it is clear there aren’t any other humans around. On the other hand, if civilizations tend to have very long lifetimes, it may be there are large numbers of technical civilizations in the galaxy. Now, one thing is clear, which is this: If there are other technical civilizations, any random one of them is likely to be vastly in advance of our own technical civilization. For example, we are only 10 or 15 years into having the technology of interstellar communication by radio astronomy. It is unlikely there is any other civilization in the galaxy that is that backward in their technical expertise. Mr. Miller. Doctor, didn’t Sir Bernard Lovell receive electrical pulses he can’t explain? Dr. Sagan. Yes, sir. There are now five objects in the heavens called pulsars, which are objects which are sending out radiation which is modulated with a frequency of about one per second; also there are sub-modulations. There are a variety of hypotheses to explain these things, some of which involve the oscillations of very old stars. There are certain difficulties with each hypothesis. The first suggestion made by the British at Cambridge, when they encountered this phenomenon was perhaps it was a beacon of some extraterrestrial civilization. That is not now their favored hypothesis. It is not clear that that is totally absurd, but in fact the scientific method to be used in that case is rather similar to the one to be used in this case. That is, it is a puzzling phenomenon. One therefore excludes all physical explanations that one possibly can before going to the much more hypothetical possibility of intelligence being involved. So, that is the present state of work in that field. For data gathering to get better information, and the refinement of the purely physical hypothesis. Well, I was saying that if there are other civilizations, many of them are likely to be far in advance of our own, and this, therefore, raises the question of how likely it is that they can traverse interstellar space and come from planets or some other star to here.

[[89]]

I should first emphasize that the distances between the stars are absolutely huge. Light, faster than which nothing can travel, takes 4½ years to get from here to the nearest star. Mr Roush. Excuse me, isn’t that a rather arbitrary statement? Dr. Sagan. I don’t think so. Perhaps you can tell me why you think it might be, then I can tell you why I think it isn’t. Mr. Roush. In my opening statement I referred to the new audacity of imagination John Dewey had spoken of. I’m thinking of imaginative terms, not factual terms. Dr. Sagan. Let me say in a sentence, why most physicists believe no material object can travel faster than light. That takes us into questions of the theory of relativity, which has had previous encounters with congressional committees, and perhaps we don’t want to go into that in very great detail. But the essential point is, that in making a few, very few assumptions, one of which was, the one we are talking about, nothing goes faster, Einstein was able to then derive a whole body of predictions which are confirmed in vast detail. Therefore, if someone says that is not a good idea, that things can travel faster than light, then they have to come up with a physical theory which explains everything we know in a way that is consistent with the idea that you can travel faster than light. No one has succeeded in doing that. Many physicists have tried. Therefore, the present belief is that you can’t. But that, of course, is a time-dependent statement. It may be that this isn’t the ultimate truth. In physics, as in much of all science, there are no permanent truths, There is a set of approximations, getting closer and closer, and people must always be ready to revise what has been in the past thought to be the absolute gospel truth. If I might say, to revise opinions, is one which is frequent in science, and less frequent in politics. [Laughter.] Dr. Sagan. So, in the context of contemporary science, I’m obviously speaking in that context, one cannot travel faster than light. So the distances between the stars are extremely large. Of course, any contemporary space vehicle would take a ridiculous amount of time to get from here to anywhere else, but we are not talking about contemporary space vehicles. The question, “Is there any conceivable method of traveling from one place to another very close to the speed of light, and therefore get reasonable transit times?” involves extrapolations of technology of a very difficult sort. However, let me merely say at least some people who have looked into the subject have concluded that it is not out of the question, even with contemporary principles of science, to imagine vehicles capable of traveling close to the speed of light, between the stars. This doesn’t mean that it happens. There may in fact be insuperable engineering difficulties we don’t know about, but there is nothing in the physics that prohibits interstellar space flight. So any estimate of how likely it is that we would be visited by an extraterrestrial intelligent civilization, depends not only on how many of them are there, but on what kind of transport they have, and how often they launch their space vehicles, even very optimistic estimates for all these numbers, gives a conclusion that an advance civilization comes here very rarely. But I again emphasize the great uncertainty in any of these numerical estimates, as they involve parts of science we don’t know very much about.

[[90]]

So, to conclude what I understand is the main reason why this committee has asked me to testify, it is not beyond any question of doubt that we can be visited. There are great difficulties from our present point of view. They are not insuperable. And if Dr. McDonald, for example, were to present me with extremely convincing evidence of an advanced technology in a UFO, I could not say to him that is impossible, because I know you can’t get from there to here, or I can’t say to him that is impossible because I know there aren’t any other guys up there. On the other hand, I would of course demand very firm evidence before I would say, well, that seems to be a very likely hypothesis. So I would like to spend Just a few minutes to come more closely to the subject of this symposium. First of all, I think it is clear to the committee, but this point should be emphasized very strongly, that there are very intense, predisposing, emotional factors in this subject. There are individuals who very strongly want to believe that UFO’s are of intelligent extraterrestrial origin. Essentially to my view, for religious motives; that is, things are so bad down here, maybe somebody from up there will come and save us from ourselves. This takes all sorts of subtle and not so subtle forms. There are also predisposing emotional factors in the other direction; people who very much want to believe UFO’s are not of intelligent extraterrestrial origins, because that would be threatening to our conception of us as being the pinnacle of creation. We would find it very upsetting to discover that we are not, that we are just a sort of two-bit civilization. It is clear that the scientific method says you don’t take either of those views, and you simply keep an open mind and pursue whatever facts are at hand with as many diverse hypotheses as possible, and try to eliminate each suggested hypothesis, and see if you are lucky with any one. I might mention that, on this symposium, there are no individuals who strongly disbelieve in the extraterrestrial origin of UFO’s and therefore there is a certain view, not necessarily one I strongly agree with — but there is a certain view this committee is not hearing today, along those lines. Finally, let me say something about the question of priorities, which Congressman Rumsfeld asked us for, and the question of significance. Now, the possibility of discovering something about extraterrestrial life, life originated on some other planet, is of the very highest interest for biology and in fact for all science. A bona fide example of extraterrestrial life even in a very simple form, would revolutionize biology. It would have both practical and fundamental scientific benefits, which are very hard to assess, it would truly be immense. Now, if the answer to this sort of profound scientific question lies right at hand, it would be folly to ignore it. If we are being visited by representatives of extraterrestrial life, just stick our heads in the sand, would be a very bad policy, I think. On the other hand, to mount a major effort to investigate these things, I think requires some harder evidence than is now at hand. It is clear that if such an effort were mounted, some information on atmospheric physics would be forthcoming. I think some information on psychology would certainly be forthcoming. I have the impression

[[91]]

that the capability of human populations to self-delusion, has not been accorded appropriate weight in these considerations. There is an interesting book published about a century ago by McKay called “Extraordinary Popular Delusions and the Madness of Crowds” which I commend to the committee. It goes into such things as alchemy, and witchcraft. After all, there have been centuries in which these things were considered to be as obviously true as anything, and yet we now know that this is really nonsense. So the possibility of these sort of delusions having a kind of contemporary guise as UFO’s should not be thrown out altogether. I do not think that explains most or all of the unidentified settings. Since the funds are so painfully tragically short for science today, the priority question boils down to this: In the search for extraterrestrial life there is a high risk, high possibility, that is the one we are talking about today; namely, UFO’s — there is a high risk that they are not of extraterrestrial origin, but if they are, we are sure going to learn a lot. Compared to that, there is a moderate risk, significant return possibility, and that is, looking for life even simple forms on nearby planets, and searching for intelligent radio communications by the techniques of radio astronomy. Here it is clear there will be significant paydirt of one sort or another for what I gather is a comparable sort of investment. So if Congress is interested, and I’m not sure it is, I think it might very well ought to be, but if Congress is interested in a pursuit of the question of extraterrestrial life, I believe it would be much better advised to support the biology, the Mariner, and Voyager programs of NASA, and the radio astronomy programs of the National Science Foundation, than to pour very much money into this study of UFO’s. On the other hand, I think a moderate support of investigations of UFO’s might very well have some scientific paydirt in it, but perhaps not the one that we are talking about today. Mr. Chairman that concludes my statement except that I request that you include for the record a statement entitled “Unidentified Flying Objects” that I prepared for the Encyclopedia Americana.

UNIDENTIFIED FLYING OBJECTS*

(by Carl Sagan)

Unidentified flying objects (UFO*s) is the generic term for moving aerial or celestial phenomena, detected visually or by radar, whose nature is not immediately understood. Interest in these objects stems from speculation that some of them are the products of civilizations beyond the earth, and from the psychological insights into contemporary human problems that this interpretation, provides. Observations. Unidentified flying objects have been described variously as rapidly moving or hovering; disc-shaped, cigar-shaped, or ball-shaped; moving silently or noisily; with a fiery exhaust, or with no exhaust whatever; accompanied by flashing lights, or uniformly glowing with a silvery cast. The diversity of the observations suggests that UFO’s have no common origin and that the use of such terms as UFO’s or “flying saucers” serves only to confuse the issue by grouping generically a variety of unrelated phenomena. In the United States, popular interest in unidentified flying objects began on June 24, 1947, when a group of rapidly moving, glistening objects was observed *In Encyclopedia Americana (New York: Grolier) and In Bull Atom. Sci, 23, (6), 43, 1967.

from the air in daytime, near Mount Rainier, Washington. The observer, a Seattle resident, dubbed them “flying saucers.” The sighting received extensive publicity. Somewhat similar sightings have been reported ever since. The differences among these observations, however, are as striking as the observations themselves. Investigations. Because of its national defense responsibility, the U.S. Air Force investigates reports of unidentified flying object over the United States. The number of sightings investigated in 1947-65 is shown in the following table.

Evaluation of these reports is difficult. Observations frequently are sketchy, and different reports of the same phenomenon are often dissimilar, or even irreconcilable. Observers tend to exaggerate. Deliberate hoaxes, some involving double-exposure photography, have been perpetrated. After allowances are made for these factors, the accepted scientific procedure is to attempt an explanation of the observations in terms of phenomena independently observed and understood. Only if an observation is rigorously inexplicable in terms of known phenomena does the scientist introduces alternative hypotheses for which there is no other evidence. Such hypotheses must still be consistent with all other available scientific information. The identity of most UFO’s has been established as belonging to one of the following categories: unconventional aircraft; aircraft under uncommon weather conditions; aircraft with unusual external light patterns; meteorological and other high-altitude balloons; artificial earth satellites; flocks of birds; reflections of searchlights or headlights off clouds; reflection of sunlight from shiny surfaces; luminescent organisms (including one case of a firefly lodged between two adjacent panes of glass in an airplane cockpit window); optical mirages and looming; lenticular cloud formations; ball lighting; sun dogs; meteors, including green fireballs; planets, especially Venus; bright stars; and the aurora borealis. Radar detection of unidentified flying objects has also occurred occasionally. Many of these sightings have been explained as radar reflections from temperature inversion layers in the atmosphere and other sources of radar “angels.” Considering the difficulties involved in tracking down visual and radar sightings, it is remarkable that all but a few percent of the reported UFO’s have been identified as naturally occurring — if sometimes unusual phenomena. It is of some interest that the UFO’s which are unidentified do not fall into one uniform category of motion, color, lighting, etc., but rather run through the same range of these variables as the identified UFO’s. In October 1957, Sputnik I, the first earth-orbiting artificial satellite, was launched. Of 1,178 UFO sightings in that year, 701 occurred between October and December. The clear implication is that Sputnik and its attendant publicity were responsible for many UFO sightings. Earlier, in July 1952, a set of visual and radar observations of unidentified flying objects over Washington, D.C., caused substantial public concern. Government concern was reflected in the creation in November of that year of a special panel to evaluate these reports. The panel was established by the Office of Scientific Intelligence of the Central Intelligence Agency, and was headed by the late Professor H. P. Robertson of the California Institute of Technology. The Robertson panel, after a thorough investigation of the UFO reports to that date, concluded that all were probably natural phenomena, wrongly interpreted. The most reliable testimony is that of the professional astronomer. Professor Jesse L. Greenstein of Mount Wilson and Palomar Observatories (author of the

[[93]]

ASTRONOMY article on pages 90-95) has pointed out that a vehicle 100 feet (30.5 meters) in diameter, at an altitude of 50 miles (80.5 km), would leave a broad track on photographic plates of the sky taken with large telescopes. This track could be distinguished easily from those of ordinary astronomical objects such as stars, meteors, and comets. Nevertheless, it appears that such tracks or unambiguous visual observations of classical UFO’s have never been made by professional astronomers. For example, in the Harvard Meteor Project performed in New Mexico during the period 1954-56, extensive photographic observations were made by Super-Schmidt cameras, with a 60° field of view. In all, a surface area of about 3,000 square miles (7,700 sq km) was observed to a height of about 50 miles (80 km) for a total period of about 3,000 hours. Visual and photographic observations were made which could detect objects almost as faint as the faintest objects visible to the naked eye. These observations by professional astronomers were made in a locale and period characterized by extensive reports of unidentified flying objects. No unexplained objects were detected, despite the fact that rapidly moving objects were being sought in a study of meteors. Similar negative results have been obtained by large numbers of astronomers and help to explain the general skepticism of the astronomical community towards flying saucer reports. A series of puzzling and well-published flying saucer sightings in the mid-1960’s again led to the appointment of a government investigating panel, this time under the aegis of the Air Force Scientific Advisory Board. It is significant that this panel was convened not at the request of the operational or intelligence arms of the Air Force, but in response to a request by the Air Force public relations office. The panel, under the chairmanship of Brian O’Brien, a member of the board, met in February 1966, and restated the general conclusions of the Robertson panel. It was recommended that the Air Force make a more thoroughgoing effort to investigate selected UFO reports of particular interest. although the probability of acquiring significant scientific information (other than psychological) seemed small. The O’Brien panel suggested that the Air Force establish a group of teams at various points within the United States in order to respond rapidly to UFO reports. The panel recommended that each team should consist of a physical scientist familiar with upper atmospheric and astronomical phenomena, a clinical psychologist, and a trained investigator. In October 1966 the University of Colorado was selected by the Air Force Office of Scientific Research to manage the program, and to prepare a thoroughgoing analysis of the UFO problem. The National Academy of Sciences agreed to appoint a panel to review the report when it is completed in early 1968. Hypotheses of Extraterrestrial Origin. Repeated sightings of UFO’s, and the persistence of the Air Force and the responsible scientific community in explaining away the sightings, have suggested to some that a conspiracy exists to conceal from the public the true nature of the UFO’s. Might not at least a small fraction of the unexplained few percent of the sightings be space vehicles of intelligent extraterrestrial beings observing the earth and its inhabitants? It now seems probable that the earth is not the only inhabited planet in the universe. There is evidence that many of the stars in the sky have planetary systems. Furthermore, research concerning the origin of life on earth suggests that the physical and chemical processes leading to the origin of life occur rapidly in the early history of the majority of planets. From the point of view of natural selection, the advantages of intelligence and technical civilization are obvious, and some scientists believe that a large number of planets within our Milky Way galaxy — perhaps as many as a million — are inhabited by technical civilizations in advance of our own. Interstellar space flight is far beyond our present technical capabilities, but there seem to be no fundamental physical objections to it. It would be rash to preclude, from our present vantage point, the possibility of its development by other civilizations. But if each of, say, a million advanced technical civilizations in our galaxy launched an interstellar spacecraft each year (and even for an advanced civilization, the launching of an interstellar space vehicle would not be a trivial undertaking), and even if all of them could reach our solar system with equal facility, our system would, on the average, be visited only once every 100,000 years. UFO enthusiasts have sometimes castigated the skeptic for his anthropocentrism. Actually, the assumption that earth is visited daily by interstellar spacecraft is far more anthropocentric — attaching as it does some overriding significance to our small planet. If our views on the frequency of intelligence in the

[[94]]

galaxy are correct, there is no reason why the earth should be singled out for interstellar visits. A greater frequency of visits could be expected if there were another planet populated by a technical civilization within our solar system, but at the present time there is no evidence for the existence of one. Related to the interstellar observer idea are the “contact” tales, contemporary reports of the landing of extraterrestrial space vehicles on earth. Unlike the UFO reports, these tales display a striking uniformity. The extraterrestrials are described as humanoid, differing from man only in some minor characteristic such as teeth, speech, or dress. The aliens — so the “contactees” report — have been observing earth and its inhabitants for many years, and express concern at “the present grave political situation.” The visitors are fearful that, left to our own devices, we will destroy our civilization. The contactee is then selected as their “chosen intermediary” with the governments and inhabitants of earth, but somehow the promised political or social intervention never materializes. Psychological Factors. The psychologist Carl Jung pointed out that the frequency and persistence of these contact tales — not one of which has been confirmed by the slightest sort of objective evidence — must be of substantial psychological significance. What need is fulfilled by a belief that unidentified flying objects are of extraterrestrial origin? It is noteworthy that in the contact tales, the spacecraft and their crews are almost never pictured as hostile. It would be very satisfying if a race of advanced and benign creatures were devoted to our welfare. The interest in unidentified flying objects derives, perhaps, not so much from scientific curiosity as from unfulfilled religious needs. Flying saucers serve, for some, to replace the gods that science has deposed. With their distant and exotic worlds and their pseudoscientific overlay, the contact accounts are acceptable to many people who reject the older religious frameworks. But precisely because people desire so intensely that unidentified flying objects be of benign, intelligent, and extraterrestrial origin, honesty requires that, in evaluating the observations, we accept only the most rigorous logic and the most convincing evidence. At the present time, there is no evidence that unambiguously connects the various flying saucer sightings and contact tales with extraterrestrial intelligence.

Dr. Sagan, there have been some recent experiments at Green Bank, W. Va., with its 300-foot telescope, in an attempt to synchronize this with the Arecibo dish, in such a way as you might in effect produce almost a 2,000-mile diameter collecting surface for trying to receive signals from the pulsars. I wonder if this isn’t the type or specific activity in radio astronomy that could utilize some additional support in order to ascertain the truth about terrestrial life and signals therefrom ? Dr. Sagan. Congressman Hechler, as a member of the faculty at Cornell that runs the observatory, I would find some problem answering that. Mr. Hechler. But not of West Virginia, however? Dr. Sagan. That is right. The study of pulsars, as I indicated to Chairman Miller, is relevant. The development of a long base-line parameter of the sort you talked about is of great interest to many areas of radio astronomy, and conceivably to the area we are talking about.

[[95]]

However, there has not been since Project OXMA, which occurred in Green Bank some 7 years or so ago, any systematic effort in this country to look for signals of intelligent extraterrestrial origin. There is at the present time a fairly major effort under way in the Soviet Union, but at least in this country there are no such efforts directed specifically to this question. It may be if we ever do detect intelligent signals from elsewhere, it will be an accidental byproduct of some other program. There is at the present time no effort to search for extraterrestrial signals. Chairman Miller. Are they trying to do things in Australia? Dr. Sagan. To the best of my knowledge there is no such work being done. Chairman Miller. The Mills-Cross program is also connected with Cornell, isn’t it? Dr. Sagan. The Cornell-Sydney Astronomy Center, yes, sir. Chairman Miller. Is that all, Mr. Hechler? Mr. Hechler. I was hoping you would suggest something more specific, for our future consideration. Dr. Sagan. Let me say, and again let me emphasize that it is by no means demonstrated that radio astronomical searches for extraterrestrial intelligence have anything whatever to do with UFO’s, but if we were interested, as some of us are, in examining the possibility of extraterrestrial intelligence, sending signals to Earth, then relatively modest programs, of say less than a, million dollars, could be organized, using largely existing instruments with only small modifications in the things you hook up to the radio telescope, which would be ideal for this purpose. There are in fact many radio astronomers who are privately interested in this sort of thing, but it carries something of the same sort of stigma that both the previous speakers mentioned about UFO’s. It is unconventional. It is in many senses radical. Many astronomers prefer to have nothing to do with it. Mr. Pettis. Mr. Chairman. Mr. Roush. Mr. Pettis. Mr. Pettis. I would like to ask the doctor, or any other member of the panel. Is there any indication that any other Government, particularly the Russians, are interested in this subject? Dr. Sagan. I cannot speak about the UFO program. Perhaps Dr. Hynek can say something about that. As far as the question that I just mentioned, the radio search for extraterrestrial intelligence, there is a state commission in the Soviet Union, for the investigation of cosmic-radio intelligence. There is a fairly major effort that has been mustered for the last few years along these lines. And there is only some information about that; that we have gotten out of the Soviet Union. I don’t know anything about their activities on UFOs. Perhaps Dr. Hynek would like to comment on that. Dr. Hynek. May I, Mr. Chairman, preface my remark, in answer to that, by pointing out a danger here that we may be putting the cart before the horse in the consideration of extraterrestrial intelligence. Speaking of horses, suppose someone comes here and tells us, or announces to us there is a report of a horse in the bath tub.

[[96]]

I think that it would be rather pointless to then ask, what is the color of the horse, what does he eat, how could be have gotten there, who installed the bath tub? The question is is there a horse in the bath tub? This is a question I think we should direct ourselves to first. Is there anything to these reports? Now, coming to the question of the Russian situation, I do know from my visits behind the Iron Curtain, or as they like to speak of it, the Socialist countries, there have been sightings behind the Iron Curtain. In fact, if you were to have good translations, it would be difficult to distinguish between a UFO report from Russia, from Brazil, from Argentina, from Japan, or from the United States. There is a rather rough pattern. Now, the Russians, to the best of my knowledge, have given no official recognition to the problem, but I do know, from personal information, that there is sort of a ground-swell interest, or a latent interest, that pops up here and there, but apparently they have as much difficulty in getting official recognition as we do. Mr. Roush. I would first point out that I realize that a visit to Russia doesn’t necessarily make a person an expert or give him all the information. A year ago June I did visit Russia. I had conversations with a few of their people, including, my pronunciation may not be correct, Dr. Millionshchikov and the head of their weather bureau, I believe it is Petrov, and several others, and I repeatedly asked the question, “Do you believe in unidentified flying objects” In each instance they merely laughed. That was the response that I got. Since then, however, I have observed there have been papers published in Russia discussing the phenomena, and discussing it in scientific terms. It seems to me that any discussion such as ours today raises the question of the existence of extraterrestrial life. That is one reason we asked Dr. Sagan to come here. I’m not real sure, Dr. Sagan, whether you stated whether there is or whether there is not extraterrestrial life. I was watching for that, and I don’t believe I heard you say it. Dr. Sagan. Congressman Roush, I have enough difficulty trying to determine if there is intelligent life on Earth, to be sure if there is intelligent life anywhere else. [Laughter.] If we knew there was life on other planets, then we would be able to save ourselves a lot of agony finding out. It is just because the problem is so significant, and we don’t have the answers at hand we need to pursue the subject. I don’t know. It beats me. Mr. Roush. I believe you coauthored a book with a Russian, is that correct? Dr. Sagan. That is correct. Mr. Roush. Does Dr. Shklovsky share your views? Dr. Sagan. I think he shares my restraint. I think both of us would say we think this is an extremely important subject, that we are on the frontier of being able to find out, but that neither of us knows whether there is or isn’t life out there. Let me say if it turns out there isn’t life on Mars, that is almost as interesting as if we find there is life on Mars, because then we have to ask, what happened different on Mars than on the Earth, so that life arose here and not there. That will surely give us a very profound entry into the question of follow-up of evolution and the cosmic context.

[[97]]

Mr. Roush. Suppose we discover there is life on Mars, in some form, wouldn’t this almost cinch your case, and you could say there is extra- terrestrial life? Dr. Sagan. Yes, sir; it certainly would, but not cinch our case about extraterrestrial intelligence. Conceivably, there might be a low form on Mars. If there is Martian life, it is of interest how low it is. If there is intelligence on Mars — but we don’t know there is intelligence on Mars — then we don’t have to grasp that evolution process. Mr. Roush. I would like to finish this mornings session just by telling of a cartoon I saw which I think Dr. Hynek perhaps saw and enjoyed as much as I did. It showed a flying saucer hovering over the Earth, with little green men looking down, and one turned to the other and said, “Do you suppose it is swamp gas?” [Laughter.] Dr. Hynek. That is a good statement to close the session on. Mr. Roush. We shall reconvene at 2 o’clock this afternoon. (Whereupon, at 12:15 p.m., the hearing was recessed to reconvene at 2 p.m.)

STATEMENT OF DR. ROBERT L. HALL, HEAD, DEPARTMENT OF SOCIOLOGY, UNIVERSITY OF ILLINOIS, CHICAGO, ILL.

  Dr. Hall. Thank you, Mr. Roush. First I should like to state a few of the rather well-established facts as they would be seen by a social psychologist. I find that when I do so, there is a great deal of redundancy. You have heard most of these facts before, so I will make my presentation brief. Fundamentally what we know that everyone can agree upon is that a great many people all over the world keep reporting some quite puzzling flying objects. In these reports there are certain recurring features, and the people so reporting often have all the characteristics of reliable witnesses. Second, the next main thing we know is that there are several strongly, often bitterly competing systems of belief about how to explain these observations, and some rational men seem to fall into line supporting each of these positions. This in itself is of course of great interest to a social psychologist. Inevitably he is interested in how systems of belief grow and are maintained. The third major factual thing that can be quite well agreed upon is that to a very large extent these alternative explanations, these systems of belief, have become rooted in organizations of people who have become committed to defending their respective positions. This greatly complicates the problem of arriving at a generally accepted explanation. In that sense, in addition to any other problems that have been defined here, clearly we have a social psychological problem also. These are very briefly the main outlines of the facts as I see them. Now, how are these explained? There are certain things that everyone seems to agree upon, or nearly everyone, I believe. First that a great many of these observations can be quite clearly identified as mistakes on the part of the observer, misidentifications of familiar objects, hoaxes, and a miscellaneous collection of similar things. Beyond that point, there comes to be a good deal of divergence in explanations, to say the least. Perhaps the major views now can be classified simply as follows: First, that these are technological devices or vehicles of some sort entering our atmosphere from the outside. Second, that this is some new, as yet ill-understood natural phenomena, something like a form of plasma, that we do not understand, and so on. The third major hypothesis to explain the hard-core cases that are not otherwise agreed upon, is that they too are simply a result of mass hysteria, and its resulting misidentifications. This hypothesis I will address myself to particularly very soon, because obviously a social psychologist has a special interest in this possibility. The three major topics that I believe I should address myself to are, first, what has brought about this complicated situation of strongly opposed beliefs that seem to resist the factual evidence, and are not responsive to each other?

[[100]]

Second, what are the probable consequences from the point of view of a sociologist or social psychologist of each of the major explanations? And third, I would like to comment quite explicitly on the hypothesis that mass hysteria and hysterical contagion is common in many of the cases. I believe I should start with the mass hysteria hypothesis. To begin with, I think there is very strong evidence that some of the cases do result from hysterical contagion in the sense that this has often been used by social psychologists. Once people are sensitized to the existence of some kind of a phenomenon (whether indeed it really exists or not), when there is an ambiguous situation requiring explanation, when there is emotion or anxiety associated with this, resulting from the uncertainty, there are precisely the conditions that have been observed repeatedly as resulting in what I shall call “improvised news.” Lacking well-verified facts and explanations, people always seem to generate the news and the explanations that will reduce the ambiguity, thereby reduce the anxiety they have about uncertain situations. There are many well-documented cases of this kind of mass hysteria and hysterical contagion. I believe it will be out of place for me to go into lengthy discussions of these episodes, but I shall comment on a few ways in which we can examine the observations of unidentified flying objects to assess whether this is a reasonable hypothesis for the hard-core cases. One of the first of these is one thoroughly familiar to attorneys, social psychologists having no monopoly on an interest in the credibility of testimony, but this is one of the principal means obviously of establishing whether we should reasonably believe certain explanations. The criteria, as most of you know, involve such things as the established reputation of the witnesses, the quality and details of the report, whether there are apparent motives for distortion or prevarication, whether there was preexisting knowledge of the thing being reported, whether there were multiple witnesses and whether there was contact among these multiple witnesses, whether observation was through more than one medium (for example, direct visual observation confirmed by radar) whether there were verifiable effects that could be observed after the reporting by witnesses, recently of the events being reported, the duration of the period in which the witness was able to observe the phenomenon; how the witnesses reacted, whether they had intense anxiety and emotion themselves, which might interfere with their observation, and so forth. These are some of the major factors, and a closely related factor in assessing the credibility of the testimony is of course an assessment of the care in gathering the testimony by interviewers themselves. How does the testimony on hard-core UFO cases look with reference to these criteria? I should say that there is a substantial subset of cases which look very good on these criteria, which make it very difficult to say that the witnesses involved were victims of hysterical contagion, grossly misinterpreting familiar things. For example, there is the Red Bluff, Calif., case in 1960, where two policemen observed for 2 hours and 15 minutes constantly, apparently

[[101]]

without tremendous anxiety or concern, an object hovering, moving about, going through gyrations. Twice it approached their police car. When they tried to approach it, it would retreat. They radioed in and requested that this object be confirmed on radar, and it was confirmed by local radar stations at approximately the same location. Ultimately, after a couple of hours of observation, they watched this object move away, join a second similar object, and then disappear. They then went to the sheriff’s office, where two deputies were present who had also seen this phenomenon, and gave similar descriptions. Now applying the criteria to a case such as this, in most respects it is very convincing. These are police officers of good reputation. Their report was prompt, thorough, careful, and in writing — and I have read the report in full. There is much detail in it of a sort that could be cross-checked with the other witnesses from the sheriff’s office. There are no apparent motives for prevarication or distortion. It was a long period of observation. I cannot establish very clearly what prior interest or information these witnesses had, but I find no indication that they had any. There was confirmation of the observation from more than one medium of observation — both visual and radar. This is the kind of case that leads me to regard the hypothesis of hysterical contagion as being quite inadequate to account for these observations. It is not a lone case; there are many others. There were trained ground observers near White Plains, N.Y., in 1954, who observed an object which they described as having the apparent size of the moon, while simultaneously they saw the moon, which was not full that night. They watched this for 20 or 30 minutes, then it moved away to the southeast. Two radar stations established fixes confirming the visually reported location. Jets were scrambled from two bases to intercept. The ground observers were able to see the jet trails approaching. Both the pilots of the jets and the ground observers report that as the jets approached, this object changed color and moved up very rapidly and disappeared, and at that point radar contact was also lost. Once again this is the kind of report that seems to me to fit the customary criteria of credibility to a very considerable degree. It is very difficult to claim that these multiple observers, trained for the type of observation they were making, confirmed independently through more than one channel, were victims of hysterical contagion. Dr. McDonald, I believe, referred briefly to the Levelland, Tex. cases in 1958, of interference with automobile ignition, in which there were 10 separate sightings in that one evening, apparently with no opportunity for the citizens involved either to read the news, hear the news of this, nor to talk with one another. They uniformly reported the same general shape. They uniformly reported — a great many of them reported also interference with automobiles ignition and headlights. This was an effect which at that time had not been observed and publicized a great deal. It subsequently has become publicized. Now, how do these cases differ from the well-known, documented cases of mass hysteria and hysterical contagion? In general those episodes have not persisted as long as the active interest in unidentified flying objects, it lasted a week or a few weeks, and it had not been too difficult to find reasonably acceptable explanations.

[[102]]

In the second place, they have not generally involved a prolonged observation of a phenomenon by people who were calm, not emotionally upset. A characteristic example of hysterical contagion would be the recent study by Back and Kerckhoff, supported by the National Science Foundation. The book reporting on this study is called “The June Bug.” It was a case of hysterical contagion among the employees of a factory in North Carolina. It is one of the most thoroughly reported and studied incidents of this sort. It resembles the kind of thing we are talking about in almost no respect. I find it very difficult to find elements in common, other than the fact that some people believed something that was difficult to verify. The employees were convinced that they were being bitten by poisonous insects, resulting in fainting and other symptoms such as rashes. All medical officers, all careful research on this, was unable to turn up any hard evidence that such an insect was present, or that there was any standard medical accounting for these symptoms. But these were people in close constant contact, sharing a particular set of problems and frustrations that raised their level of anxiety. The epidemic can be interpreted as a convenient way of escaping the problem of coping with very difficult circumstances. I have said that I think in isolated cases you can find a similar thing in observations of unidentified flying objects, but if we look at the hard-core, well-documented cases, I see practically no resemblance. Another important thing to note about the witnesses in the best sightings of UFO’s is that very commonly — as has been mentioned, I believe, by Dr. McDonald — they first try to explain their observation in some very familiar terms. This is the well-known and labeled psychological process of “assimilation.” People first try to assimilate their observation into something understood and known and familiar. This is quite contrary to the kind of argument frequently built into the hypothesis of hysterical contagion, namely, that characteristically witnesses are eager, are motivated, to see strange objects. Another important thing to notice about the witnesses in these cases is of course their reluctance to report. We have had some mention of that. This, for one thing, counters the argument of publicity seeking as a motive in some of the best cases. It incidentally runs contrary to most experience of social psychologists engaged in public opinion research, in polling, and contrary to the experience of experienced precinct workers in politics. Those people who have not tried this kind of thing expect people not to want to talk to them, but when you start ringing doorbells, the striking thing about the American people is it is often difficult to stop them from telling you what they believe. Yet in instances of unidentified flying objects, there has often been a marked reluctance to talk about them. I can illustrate this anecdotally simply to make my point. When I was on the faculty at the University of Minnesota, a student came to me, having heard that I had some interest in this question. He informed me that his father, a colonel, an artillery colonel in Korea — this was at the time of the Korean conflict — had flown over a hill in Korea in his observer plane, and found (right next to him virtually) a characteristic unidentified flying object with the usual kind of configuration. It had promptly retreated upwards. It had frightened

[[103]]

him, but he was an experienced and trained observer, so he took notes on it; he recorded it. When he returned he was so ridiculed and laughed at for a long period of time that he completely gave up trying to have this taken seriously. He refused to talk about it. I urged this student to get his father to report this to some of the private organizations that might take it seriously, and he apparently was unable to do so. The ridicule suppressed the opportunity for this information. I have encountered similar things in academic colleagues from a variety of fields, finding they are very interested and wanting to hear about this, but are afraid to talk about. In order to support the hysterical contagion hypothesis, it seems to me we need to present some plausible evidence: First, that there is a very ambiguous situation. This we can all agree upon. Second, that there is a great deal of anxiety and concern about it. This appears clearly to be the case. Third, some plausible evidence of contact among the witnesses, either directly by conversing with one another, or indirectly by being exposed to the same information, the same stimuli. In cases that I have studied. I find that this third element is the one that is often lacking, that there are often witnesses who appear not to have had prior knowledge, not to have had contact with one another, not to have been exposed, as far as we can determine, to the same news information. I might throw in here, in reference to a remark Dr. Hynek made, that the public is indeed very unwilling to accept the kinds of casual and bland explanations that have been offered. This has been my experience also, and is indeed an index of the amount of concern and anxiety about this, it appears to me. Now I will turn to another subject. I might summarize in one sentence that in my eyes the hypothesis that the hard-core cases of observed UFO’s is hysterical contagion is highly improbable. The weight of evidence is strongly against it. Now I would like to address the question of what has brought about this situation of strongly opposing beliefs that seem not to become reconciled with one another. On this I will have to digress first to explain briefly what I mean by a system of beliefs in social psychology. Perhaps the best way to explain that is to say that just as nature abhors a vacuum, nature abhors an isolated belief. Neither a belief nor the person who holds it can normally persist very long in isolation. The beliefs become organized in such a way that, for one person, his various beliefs support one another, and people gather together in organizations to lend each other support in their beliefs. This is the sense in which we have highly developed systems of belief which come to resist change, to resist evidence. The circumstances under which systems of belief such as this characteristically arise are, as I mentioned in passing before, a situation of ambiguity about a matter of importance on which there is not reliable, verified information in which people have confidence. Clearly the antidote is simple. It is to get good, reliable information which people have confidence in. This is probably the only way to weaken the irrational elements that are strongly resistant.

[[104]]

Finally, I want to comment to some extent on the probable consequences of each of the most important explanations that has been offered, and what might be done in the public interest in each instance to counter the negative aspect of these consequences. Let’s suppose to start with that these are extraterrestrial devices of some sort visiting our atmosphere. If this is the case, we for one thing have to concern ourselves with the possible consequences of contact with civilizations which are technologically very advanced and whose values we know nothing about. It is very tempting to the anthropomorphic, to attribute human characteristics to any such life form hypothesized, and to imagine, like humans, they might be hostile and might cause us some danger. I know of no hard evidence of danger, of threat, from the cases reported. But we do not have any inkling, if indeed these are extraterrestrial devices, as to their purpose. We have no hard evidence as to their purpose, their intent, their motives,so to speak. Consequently, I find it extremely difficult to even speculate in an intelligent way about what might result from contact with them. I can say a very great risk of contact, if this is the case, is the risk of panic, and panic is often very harmful to us mere humans, as in theater fires and so on. Once again from all knowledge in sociology and social psychology, the best way to counter this risk of panic is not to issue reassuring statements, but to find sound information in which people have confidence which can reduce their anxiety about the situation, and explain it adequately. This to me has been one of the most unfortunate and possibly dangerous aspects of this problem, that the ridicule, the tendency not to take the problem seriously, to issue reassurances rather than good information, has in my opinion only maximized the risk of panic, at least under this hypothesis, and I relieve under the others as well. Another risk, if these are extraterrestrial devices is clearly the risk of misinterpreting the devices as hostile devices from another country on earth, which might trigger indeed a devastating nuclear war. Once again, the same conclusions follow about the need for good information. Mr. Roush. Might not another conclusion be that if there should be something to this, again, if there should be perhaps it would bring all the people of the world together for a better understanding, a common purpose, and a common stand, which probably would relieve us of some of our own anxieties’ Dr. Hall. This is indeed within the range of possibility, though I hesitate to speculate on the probability. Mr. Roush. You don’t have to speculate. Go ahead. Dr. Hall. The final comment about probable effect, if these are indeed extraterrestrial devices, is of course the possibility of learning something of great technological value from them. The possible value of contact for purposes of advancing our knowledge of our technology. Let’s turn then to another hypothesis, which is this is a natural phenomenon which we do not understand, something like plasma. In this case, I think we have precisely the same risk of panic through misinterpretation resulting in precisely the same recommendation for the need for understanding to reduce the risk of panic.

[[105]]

I think we have precisely the same risk of misinterpretation as hostile aircraft, with again the same resulting recommendation. I think we have again the same possible great value from understanding the phenomenon in order to advance our knowledge. The third major hypothesis, explanation, which I cited above, is that even the most solid and plausible cases reported are results of mass hysteria and hysterical contagion. I simply note that if this is the case, I regard it as prima facie evidence that we badly need to improve our understanding of mass hysteria, of the process of belief formation, of the means by which we might control the kinds of anxiety that produce this problem. In this situation there is still the dangerous risk of panic, even if there is no physical phenomenon underlying these reports. There is still the risk of misinterpretation of hostile aircraft, and I would submit that there is still the great potential benefit from studying it thoroughly and scientifically, in this case the gain being a gain in sociological and psychological knowledge, which would be of obvious importance if all of this is caused simply by mass hysteria. I have a few conclusions and recommendations which I have written out. I will try to tie these to what others have said as I go along. My first conclusion would be that no matter what explanation you accept, we have here a rare opportunity for gaining some useful knowledge by a thorough detached study of UFO reports, and a systematic gathering of new information, hopefully with good instrumentation, and good, well-trained interviewing teams. My second conclusion would be that hysteria and contagion of belief can account for some of the reports, but there is strong evidence that there is some physical phenomena underlying a portion of the reports. Third, I would conclude that because of the lack of trustworthy information the systems of conflicting beliefs has been built up to account for a very ambiguous set of circumstances. Each of these positions is sometimes defended beyond the point of rationality. Fourth, I would repeat my earlier statement as a conclusion, that whether or not there is a physical phenomenon underlying a portion of the reports, we clearly have a social psychological problem of subduing these irrational systems of belief, defense of beliefs, of lowering the anxiety about these reports, and of reducing the ambiguity about their nature. The recommendations that I had written out were two — excuse me, were three, and overlap considerably with the comments of my colleagues. I would say that the most important matter is to promote the fullest possible free circulation of all the available information about this phenomena. This should help reduce risks of panic and other dangerous irrational actions. It should help to weaken these systems of belief, the irrational elements in them. Here I would say indifference, or disinterest on the part of national leaders can retard our learning about this phenomenon, and open interest and encouragement can help. I believe you are performing a fine service in having this kind of open inquiry. This whole matter badly needs to be treated as something deserving serious study. The second recommendation I have to make concerns some general lines of research that would seem to me called for. One of these seems

[[106]]

to me would be to take the 100 or 200 cases per year that seem to be reliably reported and reasonably well documented, and to study them carefully for recurring patterns’ with emphasis on the way they react to their environment, the way they react to light sources, the way they react to presence of humans and so on. The second form of research would be, I think to study explicitly those portions of the problem that do result from mass hysteria, apparently. These need to be studied intensively, quite apart from the question of the physical phenomena, to improve our understanding of mass hysteria and panic, and its possibly dangerous consequences. In doing this I think it is terribly important that particular observations be studied by the scientists of a variety of disciplines, that the study of the hysteria hypothesis not be separated from the others. If it is, there is a tendency to make this hypothesis the garbage can for otherwise unexplained sightings. The third type of study that seems to me terribly important, but my colleagues at the table can speak with more authority than I, is the systematic gathering of new cases with good scientific instrumentation, the kind of work in quantitative evidence that would give us much more to go on. The third recommendation I had to suggest was that possibly in addition to a careful scientific investigation and study of this phenomenon, it might be fruitful to set up formally an adversary proceeding modeled after our system of jurisprudence. There is a tendency for us academics to sit on fences as long as we possibly can, and I think that if there were several teams of investigators who were assigned the responsibility much the way a prosecuting attorney or defense attorney is, assigned the responsibility to make the strongest possible case for one of the systems of explanation, that this would challenge the others, and force them to find more solid evidence. It would try to benefit from some of the valuable features we have in our system of jurisprudence. That concludes my presentation, except to comment briefly on how this relates to the suggestion of my colleagues. I would certainly enthusiastically agree with Dr. Hynek’s suggestion of a board of inquiry, or some competent group to study the phenomenon. I would certainly agree with Dr. McDonald’s view that a variety of approaches would be fruitful, that a single study has many disadvantages. I have taken an interest for a number of years in the problems of the support of academic institutions by Government and I think that we are most likely to proceed to some good knowledge rapidly if we don’t put all our eggs in one basket. I certainly agree with Dr. Sagan’s view that there are these very intense predisposing emotional factors for each of these beliefs. Somehow we need to weaken those. Finally, on the idea of UN cooperation, this had not occurred to me, but I think it is an excellent idea. If it is possible to establish some detached international agency that can bring about free, open flow of information, and some cooperation internationally in investigating this, it would be helpful. Thank you, Mr. Roush. Mr. Roush. Thank you, Dr. Hall. Are there questions?

PREPARED STATEMENT BY ROBERT L. HALL

From the point of view of a social psychologist, UFO reports present us with a most interesting and challenging situation. To a social psychologist the known facts appear to be facts about people and the things that they are saying and doing. First, many people, all over the world, including reliable and knowledgeable witnesses, keep reporting puzzling flying objects, and the reports have certain recurrent features. Second, several competing systems of belief have grown up to explain these reports, with some rational men supporting each of several different explanations. Third, as any sociologist would predict, the systems of belief have, to a large extent, become rooted in complex organizations of people: some organizations have been created to defend a particular position about UFOs; some organizations whose main purposes are remote from UFOs have been drawn into .the controversy and found themselves committed to defending a position. Nearly all rational observers appear to be agreed that the great majority of reported sightings of unidentified flying objects (UFOs) can be explained as misidentifications of familiar phenomena, with an occasional hoax contributing to the confusion. However, there are approximately 100 to 200 cases per year, based upon apparently sound testimony, with recurrent features of appearance, movement, and reaction to the environment. Strong disagreement arises over these cases. One major area of disagreement is the question whether any novel physical phenomenon underlies these reports or whether they are simply a miscellaneous collection of familiar phenomena, misidentified because of mass hysteria and misperceived as having recurrent features because of a process of hysterical contagion. Among those who believe that there is a physical phenomenon, there are, in turn, several alternative explanations as to what it is. A substantial number argue that there are technological devices or vehicles entering our atmosphere from the outside. A substantial number argue that there is a novel natural phenomenon, as yet ill understood, such as a form of plasma or “ball lightning.” There are other explanations supported by some people, such as the belief that “space animals” are swimming around in our atmosphere, or that these objects are secret devices manufactured somewhere on earth. In my judgment these last two explanations fit the available evidence so poorly that I shall not deal with them further. We might, then, label the three major hypotheses: (1) Mass hysteria and contagion; (2) Extraterrestrial devices; (3) New natural phenomenon. My comments, as a social psychologist, will be organized around three major questions: (1) What has brought about this situation of competing systems of belief, strongly held and often unresponsive to the observed facts, and how can we modify the situation? (2) Is the mass hysteria hypothesis a plausible one, and can it account adequately for the known facts? (3) For each of the major explanations, what would be the probable consequences if the explanation were true, and what actions or precautions might be taken in the public interest? How did the present situation come about? Much sociological research on rumor and belief systems indicates that ambiguity about an important matter begets improvised news. To the extent that trusted information is not available. systems of belief are generated to fill the gap. A recent scholarly work by Shibutani describes a rumor as a kind of improvised news which “… arises in situations of tension when ordinary communication channels are not operating adequately.” (Shibutani, 1966, p. 57). Shibutani further argues that people are always being confronted with new circumstances which are not clearly and adequately treated by trusted channels of information, and therefore rumors are a normal and important part of men’s efforts to adapt to their environment (p. 161, 182-183). Alternative explanations of UFO reports have arisen because of a lack of sound, authoritative information in which people have confidence. This is a normal and usual reaction to such situations of ambiguity. In order to complete my answer about how the present situation came about, I must digress briefly to explain what I mean by a “system of belief.” Just as nature abhors a vacuum, nature abhors an isolated belief. Neither a belief nor the person who holds it can normally persist long in isolation. Each person’s beliefs tend to become organized into an interdependent system of beliefs which support one another. Also, people who share important beliefs typically become

[[108]]

organized into social groups in which members support one another’s beliefs. Hence a particular belief, such as the belief that there is no new physical phenomenon underlying UFO reports, is intricately tied in with two systems — a system of related beliefs by the same person, and a social system of people who share similar beliefs. Many social psychologists have analyzed and documented this kind of phenomenon (e.g., Festinger, 1957; Simmons. 1964; Smith, Bruner, and White, 1950). In circumstances such as those described, the ambiguous situation is often associated with widespread anxiety, and the belief systems which arise characteristically contain elements of hysteria which may increase the likelihood of panic or other irrational action (see Smelser, 1963). New beliefs which are improvised to reduce the ambiguity often are assimilated into preexisting belief systems, such as the beliefs of religious cults, so that, in effect, the ambiguous situation is used to manufacture support for preexisting beliefs. Once a situation of competing belief systems is established, probably the only way to modify it very much is by attacking the conditions which brought it about — that is, the lack of authoritative, trusted information. My second major question, stated above, was: “Is the mass hysteria hypothesis a plausible one, and can it account adequately for the known facts?” First, let me reiterate the facts which we are trying to explain: numerous reliable reports, and recurrent features in these reports. When a large number of people report observations that share many details of appearance and behavior, one of three things must be the case: either they are observing the same phenomenon, or they have been exposed to the same sources of information which have influenced them to expect to see certain things, or they have been in mutual contact and influenced one another in some fashion. If the mass hysteria, hypothesis is to beheld plausible, we need to show that separate people reporting the same details have been in touch with each other or with some common source of information. The independence of the separate observers becomes a crucial question. In determining the plausibility of this hypothesis, a second major concern is the credibility of testimony. Much of our legal system is based upon the assumption that we can, under appropriate conditions, accept human testimony as factual. Social psychologists are certainly not alone in having developed criteria for assessing the credibility of testimony; attorneys are thoroughly familiar with such criteria. In assessing testimony we customarily consider such questions about the witness as his reputation in his community, whether he has any apparent motive for prevarication or distortion, whether he has previous familiarity with the things reported. In addition we consider internal characteristics of his report, such as the recency and duration of the events reported, the number and type of specific observable details reported as apart from reports that are primarily interpretations, the inclusion of details that are independently verifiable (such as physical effects). Also testimony is, of course, more credible if there are multiple witnesses, especially ones who are completely independent of one another; if there have been different means of observation (e.g., both visual and auditory, or unaided observation and observation through instruments); and if the testimony is gathered by qualified, careful interviewers. In my judgment there are many reports of UFOs that meet the above criteria quite well — better, indeed, than many court cases which a judge and jury accept. In some of these cases, no familiar explanation can be found that fits the evidence. I shall digress briefly to describe a few cases. Consider the case of two police officers near Red Bluff, California, on August 13, 1960. They saw a large object descending and at first thought it was an airliner about to crash. They jumped from their patrol car and noticed that the object made no discernible noise. They watched it descend to an estimated 100 or 200 feet, then reverse itself at high speed, and finally stop and hover at an estimated 500 feet. They described details of shape, color, and movement. They radioed the sheriff’s office to contact a local radar base and were informed that the radar base reported an unidentified radar return at the same location as their visual observation. They reported details of the object’s behavior and their own. They tried to approach the object and it retreated; when they remained stationary, the object approached their car. They reported that the object retreated when they turned on the patrol car’s red light. After prolonged observation the object began to move away, and they followed slowly. They saw it join another similar object and finally disappear over the horizon. Altogether they watched the object for about two hours and fifteen minutes. Their report was prompt, thorough and

[[109]]

written, and contained details which are contained in many other UFO reports. Immediately after losing sight of the object, the officers returned to the sheriff’s office and met two deputies who reported the same observation. The officers were men of good reputation, and there is no indication of prior interest in UFOs nor prior knowledge of the kinds of details reported (e.g. the red light beam emitted by the object and radio interference each time it came near). These men have subsequently been contacted by people with scientific training and have confirmed various details of their report. Another case of interest occurred near White Plains, New York, in late summer, 1954, and was reported by James Beatty, an experienced ground observer corps supervisor in an Air Force Filter Center. At about 9:50 p.m. an observer team about 20 miles southeast of Poughkeepsie saw an object similar in apparent size to the moon. At the same time they could see the moon, which was not full. They watched the object for about 20 or 30 minutes and then it moved slowly southeastward. According to the report of the supervisor, two radar stations had fixes corresponding to the visual sighting, and jets were scrambled from two airbases. As the jets approached the object, both the pilots and the ground observers report that the object changed color, moved upward at very high speed, and disappeared. At this point radar contact was lost, too. In the vicinity of Levelland, Texas, on the night of November 2-3, 1957, there were ten separate sightings by several people, including police officers, over a period of approximately 2 1/2 hours. The descriptions were similar in several important details of visual appearance. Several observers independently reported that their cars’ engines and headlights quit working when the object was close. This kind of effect has been frequently reported but had not been publicized prior to this group of reports in Levelland. In most instances it is clear that the witnesses around Levelland were going about their usual business and were surprised by the sighting; they had not been alerted to watch for a strange object. These are only three cases out of many (see Hall, 1964, and U.S. Air Force, 1968). They are reported only sketchily here, but much more detail is available (see Hall, 1964). I introduce them only to illustrate the kinds of evidence available relevant to the hypothesis of mass hysteria to account for UFO sightings. I am forced to the conclusions that there are many sightings by multiple observers and that many observers are reliable and independently report similar details. In many instances it appears highly unlikely that they could have been exposed to similar detailed information in advance (e.g., the electrical interference effects at Levelland). Social psychologists have studied a number of cases of mass hysteria and hysterical contagion (Cantril, 1940; Johnson, 1945; Kerckhoff & Back, 1968; Medalia & Larsen, 1958). In my judgment the “hard-core” reports of UFOs do not resemble those documented cases. Those cases were generally short-lived — a day, a week, or at most a few weeks; UFO reports have persisted for decades, at least, despite much ridicule and very little recent press coverage of serious cases. The documented cases of mass hysteria have not involved calm, prolonged observations such as the police officers near Red Bluff, California. The documented cases have had some plausible indication that the people involved have been in touch with one another (Kerckhoff & Back, 1968) or previously exposed in common to the information that they incorporate into a report (e.g., Johnson, 1945; Medalia & Larsen, 1958). The documented cases have not been worldwide, as are UFO reports. They have not involved phenomena that were simultaneously observed through such different media as direct visual contact and radar contact. In documented cases of mass hysteria I do not know of evidence of people reluctant to report; in UFO sightings there are numerous such cases. The hypothesis of mass hysteria does not, in my judgment, fit the “hard-core” reports very satisfactorily. The third, and last, of the three major questions which I raised at the beginning was: For each of the major explanations, what are the likely consequences, and what actions or precautions might we take in the public interest? First, let us suppose that there are extraterrestrial devices entering our atmosphere from the outside. We must then concern ourselves with the possible consequences of contact with technologically advanced civilizations whose values, or intentions, or motives are totally unknown to us. It appears to me an almost impossible task to predict the probable effects of contact between our earthly civilization and another civilization without making some clearcut assumptions about their values and motives. I have not been able to find any rational basis for defending particular assumptions of this kind, and I shall not attempt

[[110]]

the task. We must also be concerned with the risks of panic resulting in people hurting one another, even if the assumed extraterrestrial visitors mean no harm. This risk could be markedly reduced by preparing the public for the eventuality — by treating it as a serious possibility that must be discussed. The greatest risk of panic would come from a dramatic confrontation between the assumed “visitors” and a collection of humans who were unprepared and had been told that their leaders did not believe such visitors existed. Another risk is that we might misinterpret such devices as weapons of another country and thereby accidentally trigger nuclear war. If these are extraterrestrial devices, we have, of course, a great opportunity to learn from their technology, which would appear to be very advanced in certain respects by our terrestrial standards. Second, let us suppose that this is a novel natural phenomenon which we do not understand. Under this assumption we still run the risk of panic if a crowd of people are confronted with a case of the phenomenon without any preparation. We still run the risk of misinterpreting an occurrence as a hostile weapon system. Also, it is a reasonable assumption that we might reap scientific and technological benefit from understanding such a puzzling thing that appears to involve some kind of concentration of energy. Third, let us suppose that the whole persistent business of UFO reports over the years is strictly a social psychological phenomenon—a new and extreme case of mass hysteria and hysterical contagion. In this event the underlying anxiety must indeed be massive and the risk of panic accordingly very great unless we can introduce trusted information and reduce the ambiguity and anxiety. Under this assumption — if atmospheric and astronomical observations can be so badly misinterpreted and so badly reported by many people of good reputation and good education — then I would judge that we run great risk of misinterpreting those same phenomena as hostile weapons, and we must prepare for this risk. Most important, if this whole business is a social psychological phenomenon, then this is prima facie evidence of the urgent need to improve our understanding of the processes of mass hysteria, belief formation, and means of controlling the kinds of anxiety that generate such a problem. In this event the UFO reports present an unsurpassed natural laboratory for research on mass hysteria, human response to ambiguity, standards for assessment of human testimony, and other related matters.

CONCLUSIONS

1. No matter which explanation is correct, we have a rare opportunity for gaining useful knowledge by a thorough, detached study of UFO reports and a more systematic gathering of new evidence. 2. Hysteria and contagion of belief can account for some of the reports of UFOs, but the weight of evidence suggests strongly that there must be some kind of physical phenomenon which underlies a portion of the reports. 3. Because of the lack of trustworthy information about UFO reports, systems of conflicting belief have been built up to account for this ambiguous set of circumstances, and each position is sometimes defended beyond the point of rationality. 4. Whether or not there is a physical phenomenon underlying a portion of the reports, we now have, in addition to any other problem, a social psychological problem of subduing irrational defense of beliefs, lowering anxiety about the reports, and reducing ambiguity about the causes of the reports. 5. Our lack of understanding of UFO reports forces us to run unnecessary risks of panic and of accidental triggering of nuclear war.

RECOMMENDATIONS

1. The most important and urgent matter is to promote the fullest possible circulation of all available information about UFOs and to encourage systematic gathering of new evidence. This should help to reduce the risks of panic and other dangerous irrational actions. This should also help to weaken the irrational elements incorporated into opposing systems of belief. Indifference or disinterest on the part of national leaders can retard our learning about the phenomenon at hand; open interest and encouragement can help. The whole matter needs to be treated as something deserving serious study. 2. At least three lines of serious research should be undertaken: (a) For the 100 to 200 cases per year that are reliably reported and well documented, we need to study carefully reports of recurring patterns of behavior by the phenomenon,

[[111]]

including its apparent reaction to other events in the environment with emphasis upon establishing independence or non-independence of separate witnesses, (b) Those portions of the problem that result from mass hysteria need to be studied intensively to improve our understanding of mass hysteria toward the end of controlling its potentially dangerous consequences, (c) Some systematic means of monitoring and observing should be developed so as to add well documented new cases with specific reports of details obtained independently from different observers. 3. Serious consideration might be given to the idea of setting up a formal adversary proceeding, modeled after our system of justice. Just as courts have attorneys assigned to build the best possible case for the prosecution and others to build the best case for defense, we might have a staff assigned to build the strongest possible case for each of the three major explanations of UFO reports. If each had to confront the others and answer their criticisms, we would probably force a clearer focus on the crucial points that need to be settled. My closing comment returns to my starting point. The situation that we face in UFO reports is an exciting and challenging one which presents a rare scientific opportunity, no matter whose interpretation and explanation you may accept.

STATEMENT OF DR. JAMES A. HARDER, ASSOCIATE PROFESSOR OF CIVIL ENGINEERING, UNIVERSITY OF CALIFORNIA AT BERKELEY, CALIF.

Dr. Harder. Thank you, Mr. Chairman. Your committee has asked me to comment on the problem of propulsion as raised by some reports, and to whatever potential benefits there might be to the aerospace programs from an intense scrutiny of UFO phenomena. I am very glad for this opportunity to present to your committee some of my views on the problems of unidentified flying objects and to indicate some of the areas in which I think a closer investigation of this problem might provide us with scientific clues that would give us important impetus to basic and applied research in the United States. As Dr. Hall has said, there have been strong feelings aroused about UFO’s, particularly about the extraterrestrial hypothesis for their origin. This is entirely understandable, in view of man’s historic record of considering himself the central figure in the natural scene; the extraterrestrial hypothesis tends inevitably to undermine the collective ego of the human race. These feelings have no place in the scientific assessment of facts, but I confess that they have at times affected me. Over the past 20 years a vast amount of evidence has been accumulating that bears on the existence of UFO’s. Most of this is little known to the general public or to most scientists. But on the basis of the data and ordinary rules of evidence, as would be applied in civil or criminal courts, the physical reality of UFO’s has been proved beyond a reasonable doubt. With some effort, we can accept this on an intellectual level but find a difficulty in accepting it on an emotional level, in such a way that the facts give a feeling of reality. In this respect, we might recall the attitude many of us have toward our own deaths: We accept the facts intellectually, but find it difficult to accept them emotionally. Indeed, there are flying saucer cultists who are as enthusiastic as they are naive about UFO’ s — who see in them some messianic symbols — they have a counterpart in those individuals who exhibit a morbid preoccupation with death. Most of the rest of us don’t like to think or hear about it. This, it seems to me, accurately reflects many of our attitudes toward the reality of UFOs — natural, and somewhat healthy, but not scientific. In my remaining statements you will note that I have tacitly assumed the reality of UFO’s as a hypothesis underlying my assessment of the importance of this subject for scientific study.

1. THE UFO PROPULSION PROBLEM

By way of introducing the propulsion problem of UFO’s, I will review a sighting near the city of Corning, in northern California, during the night of August 13, 1960, by two California highway

[[113]]

patrolmen. During that night, and several succeeding nights, there were many reports of UFO’s over northern California, but this particular event is important not only because of the fact that it has been well authenticated but because of the relatively long time and close nature of the observations. My condensed description that follows is from the official report filed the next day by the two officers (see appendix I and II) from a half-hour taped interview conducted 3 days later by myself and Dr. Carl Johannessen, of the University of Oregon; from a letter written by Officer Charles A. Carson to Walter N. Webb, Charles Hayden Planetarium, Boston, Mass., dated November 14, 1960; and from a telephoned interview conducted by Dr. James McDonald with Mr. Carson on October 27, 1966.

APPENDIX I

ADDITIONAL WITNESSES TO THE EVENTS OF AUGUST 13, 1960

When Officer Scott radioed the Tehama County Sheriff’s Office, two deputies, Fry and Montgomery, traveled to Los Molinos, somewhat northeast of the first sighting, from which point they observed the UFO simultaneously, though at a greater distance, with Scott and Carson. The night jailer, from a point further north, saw it, and marched his several prisoners out onto the roof of the jail, each of whom saw it. Subsequently, due to newspaper publicity, Carson received a number of letters from motorists who had seen the object while traveling along Highway 99E. After Scott and Carson returned to the Sheriff’s Office, they called the radar base again, and talked with the operator while all of them listened in on various extensions. He described to them some of the movements of the object as he had observed it on the radar screen; these corresponded to the movements they had observed. Several months later, in a personal interview conducted on January 3, 1961, Captain Blohl, Area Commander at Red Bluff, stated that both Scott and Carson had worked for him for three or four years, and that he had the highest regard for their honesty and devotion to duty. They were not publicity minded, he said. Of Scott, he remarked, “Scotty would rather take a knife or a gun away from a man than make a speech.” In the unwanted publicity that was forced upon them, Blohl stated that their story stood up unaltered — that there were no baubles [sic] during question periods.

APPENDIX II

REPORT OF OFFICERS CARSON AND SCOTT TO STATE HIGHWAY PATROL AREA COMMANDER

August 13, 1960. To: Area Commander, Red Bluff. From: C. A. Carson, No. 2358, S. B. Scott, No. 1851. Subject: Unidentified Flying Object. Sir: Officer Scott and I were eastbound on Hoag Road, east of Corning looking for a speeding motorcycle when we saw what at first appeared to be a huge airliner dropping from the sky. The object was very low and directly in front of us. We stopped and leaped from the patrol vehicle in order to get a position on what we were sure was going to be an airplane crash. From our position outside the car the first thing we noticed was an absolute silence. Still assuming it to be an aircraft with power off we continued to watch until the object was probably within 100′ to 200′ of the ground when it suddenly reversed completely, at high speed and gained approx. 500′ altitude. There the object stopped. At this time it was clearly visible to both of us, and obviously not an aircraft of any design familiar to us. It was surrounded by a glow making the round or oblong object visible. At each end, or each side of the object, there were definite red lights. At times about 5 white lights were visible between the red lights. As we watched, the object moved again and performed aerial feats that were actually unbelievable. At this time we radioed Tehama County Sheriff’s Office requesting they contact the local radar base. The radar base confirmed the U.F.O. — completely unidentified.

[[114]]

Officer Scott and myself, after our verification, continued to watch the object. On two occasions the object came directly towards the patrol vehicle. Each time it approached the object turned, swept the area with a huge red light. Officer Scott turned the red light on the patrol vehicle towards the object and it immediately went away from us. We observed the object use the red beam approximately 6 or 7 times, sweeping the sky and ground areas. The object began moving slowly in an easterly direction and we followed. We proceeded to the Vina Plains Fire Station where we again were able to locate the object. As we watched it was approached by a similar object from the south. It moved near the first object and both stopped, remaining in that position for some time, occasionally emitting the red beam. Finally both objects disappeared below the eastern horizon. We returned to the Sheriff’s Office and met Deputy Fry and Deputy Montgomery, who had gone to Los Molinos after contacting the radar base. Both had seen the U.F.O. clearly and described to us what we saw. The night jailer also was able to see the object for a short time, each described the object and its maneuvers exactly as we saw them. We first saw the object at 2350 hours and observed it for approx. 2 hours and 15 minutes. Each time the object neared us we experienced radio interference. Sir, we submit this report in confidence, for your information, we were calm after our initial shock and decided to observe and record all we could of the object. Charles A. Carson, No. 2358. S. B. Scott, No. 1851. Officers Scott and Carson were searching for a speeding motorcyclist along Hoag Road, east of Corning, Calif., between U.S. Highway No. 99W and 99E when they saw what at first appeared to be a huge airliner dropping from the sky. This was at 11:50 p.m. They stopped and leaped from the patrol car in order to get a position on what they were sure was going to be an airplane crash. From their position outside the car the first thing they noticed was an absolute silence. Still assuming it to be an aircraft with power off, they continued to watch until the object was probably within 100 to 200 feet off the ground, whereupon it suddenly reversed completely, traveling at high speed back up the 45-degree glide path it had been taking, and gaining about 500-feet altitude. This observation was from a distance of one-half to 1 mile. They said it was about the size of a DC-6 without wings; Officer Carson later made a sketch which shows an elliptical object 150 feet long and 40 feet high. It was a very clear night, with no clouds, and as the object hovered for about a minute they got a good look at it. It was obviously not an aircraft of any design familiar to them, they said. It was surrounded by a white glow, making the object visible. At each end there were definite red lights, and at times five white lights were visible between the two red lights. They called the night dispatching office at the county sheriff’s office and asked that other cars be sent, and that all other cars in the area be alerted. They also asked the radar base be notified. The object then drifted westward toward them, losing altitude, and got within some 150 yards of them, easy pistol range, before drifting eastward again. During this time it performed aerial feats that seemed unbelievable. It was capable of moving in any direction — up, down, back, and forth. At times the movement was very slow, and at times completely motionless. It could move at extremely high speeds, and several times they watched it change direction or reverse itself while moving at unbelievable speeds.

[[115]]

As the object moved away from them toward the east, they followed at a judicial distance, encouraged by the expectation that they were to be joined by other officers. At that time they also radioed the Tehama County Sheriff’s Office requesting that they contact the local radar base. By telephone the radar operator confirmed the UFO and stated that it was unidentified. The two officers drove the next day to the local radar base, were refused permission to talk to the radar operator that had been on duty, and were given what Carson described as the “ice water treatment” by the commanding officer. There follow many interesting details of their hide-and-seek chase with the object over the next 2 hours along the back roads of northern California, trying to get close enough to this thing to get a better observation. It seemed always to know they were there and always kept about half a mile away. However, when we restrict our attention to the propulsion problem, the significant facts are: (1) there was no observable noise, (2) the UFO could hover — seemed to float as if it were in water — and move in any direction without altering its orientation, (3) it could sustain very high accelerations and move very rapidly, (4) it was able to hover or to move relatively slowly for at least 2 hours under circumstances that precluded suspension by aerodynamic lift forces. What can we learn about the propulsion of UFO’s from the information provided by the observations of these two police officers? Mainly, it is negative information. From the silence it seems impossible that it could have been supported by a jet or rocket reaction. There are further considerations involving specific impulse, energy, et cetera, that we need not go into here, that provide compelling arguments against any conventional way of counteracting the earth’s gravitational field. There remains a slight possibility of developing sufficient reactive force by expelling relativistic neutrinos, for they would not be intercepted by the earth under a UFO and would not be noticed. Expelling neutrons would have this same advantage, but in the quantities required they would induce far more radioactivity than has ever been measured at sites where UFO’s have come close to the ground or have been reported to have landed. Fortunately, there has been at least one observation that tends to provide a bit of positive information. Mr. Wells Allen Webb, an applied chemist with a master of science degree from the University of California, was 1 mile north of Spain Flying Field, 7 miles east of Yuma, Ariz., just off U.S. Highway No. 80, when his attention was drawn to the sky to the north by some low-flying jet aircraft. Then he noticed a small white cloud-like object in an otherwise cloudless sky. He watched for about 5 minutes as it traveled eastward; as it reached a spot north-northeast of his location, it abruptly altered shape from being oblong and subtending about half the angle of the full moon — about 15 minutes of arc — to be circular and subtending about 5 minutes of arc. Webb was wearing polaroid glasses and noted that there appeared around the object a series of dark rings, the outermost of which was about six times the diameter of the central white or silvery object, or about the diameter of the full moon. The object

[[116]]

or cloud then decreased in apparent diameter, as if it were traveling away from him, and disappeared in another few minutes. During this time Webb repeatedly took off his glasses and then put them back on, noting each time that the rings appeared only when he was wearing the glasses. He did not know what to make of the sighting, but took notes, including the fact that it was about 10 in the morning. The date was May 5,1953. One of the first things to note about the situation as described in the account is that the dark rings were observed with polaroid glasses, but not without them. The second thing is that, from the orientation of the observer relative to the position of the sun at that time of day, the blue scattered light from the part of the sky that formed the background for the object was polarized. To this fortunate circumstance we must add the fact that Mr. Webb was curious about clouds, the effect of viewing them with polarized light, and took notes of what he observed. He did not, however, realize that he was observing the rotation of the plane of polarization of the blue light in the vicinity of the object. This was the interpretation I made some 8 years later upon reading his account. Mr. Wydler. How would you define UFO’s as you are using it in this paper before us. Dr. Harder. I don’t know how I could define it without being circular. Mr. Wydler. That is the conclusion to which I came. You state on the very first page or you more or less say you are going to tacitly assume the reality of UFO’s, merely an “unidentified flying object.” I think we can assume their reality without worrying much about it. It is only if they have some particular interplanetary significance that might become a real problem, the way we look at it, isn’t that so? We all agree there are unidentified flying objects. I think you are defining them as interplanetary. I don’t see you really come out and say that, but I think you hinted at it. Dr. Harder. Well, if my interpretation of these rings is correct, it is certainly nothing we have been able to accomplish on earth. Mr. Wydler. Are you saying, when you use this term, for the purposes of your statement, in your testimony, you are assuming they are of an interplanetary nature? Dr. Harder. Yes, that is right. Mr. Wydler. All right. Dr. Harder. In my statement, which is available to the transcriber, I have gone through a little bit of argument suggesting why the outer of the three rings represents light that had been rotated through 90 degrees, so it would not pass through the polarizer, if it is polarized glasses. The next ring represented light that had been rotated 90 plus 180 degrees. If you have polaroid glasses and look at the right part of the blue sky, any afternoon, you can seen that the light is polarized, and as you rotate your polaroid glasses there is an alternate darkening-lightening, as you go through 180 degrees. We can assume, to begin with, that the plane of the polarizer in his glasses was parallel to the plane of the undisturbed polarized light from the general direction of the object. If then something affected the light so as to turn its plane of polarization through 90 degrees, the portion that had been originally polarized would not pass through

[[117]]

the glasses. Likewise, for light that had had its plane of polarization turned through 90 plus 180 degrees, 90 plus 360 degrees, and so on, there would be a partial extinction of light. On this basis, the outer dark ring was due to the rejection by the polarizing filter of the glasses of light which had had its plane of polarization turned through 90 degrees, the next outermost band by light that had been turned through 27O degrees, et cetera. This interpretation is strengthened by Webb’s observation that the dark rings were narrower than the brighter areas between them; this is what should be expected on the basis of the above explanation. What hypotheses can be constructed that might account for this unusual observation? There are at least two that have interesting implications for the propulsion problem. First by the Faraday effect, a magnetic field parallel to the path of the light could so rotate the plane of polarization. A quick calculation using the properties of the atmosphere shows that a field of 200,000 gauss, operating over a distance of 130 feet — 40 meters — could turn the plane 90 degrees; this is indeed a very intense and extensive magnetic field and, of course, would only account for one ring. Three rings would require a million gauss over the same distance. We have been able to achieve these field strengths in the laboratory for only fractions of seconds over very small distances. However, the principal argument against this hypothesis is the conclusion that were such a field brought at all close to the surface of the earth its effect would be to induce very strong remnant magnetism in nearly every piece of iron within several hundred yards. This has not been found. We have been able to achieve that kind of field strength for fractions of seconds only over short distances on earth, or at least we, on earth. [sic] [NCAS Editor’s note: apparent severe garble in the transcription] However, there has been a suggestion made earlier that a very strong magnetic field might so saturate certain iron cores of electrical machinery as to explain some of the observed phenomena of electrical malfunctioning. Despite the above-described observation, there is little reason to believe that magnetic fields, of themselves could be of much use in propelling a spacecraft, although there has been much uninformed speculation about this in popular UFO publications. The simple reason is that we cannot produce a north pole without at the same time producing a south pole. Tills is a consequence of fundamental theory. Such a dipole cannot exert a force in conjunction with a uniform magnetic field, such as the earth may be assumed to have in a given locality, though it can produce a force in a nonuniform field. To go beyond the above discussion would be rather speculative, but it is just here that we find a stimulus and challenge to scientific theory. It is almost circular to say that when we find a phenomenon we understand but vaguely we have also found a means of advancing our understanding; this has been particularly true in astronomy. Concerning the propulsion of UFO’s, a tentative hypothesis would be that it is connected with an application of gravitational fields that we do not understand. Gravitation remains one of the enigmas of modern science, although there have been some advances in its understanding, beyond general

[[118]]

relativity, in the past decade. There are theoretical grounds for believing there must exist a second gravitational field, corresponding to the magnetic field in electromagnetic theory, and that the interaction between these two fields must be similar to that between the electric and magnetic fields. This interaction and its exploitation forms the basis for our modern electrical generators and motors. Without the interaction, we would be back to the days of electrostatic attraction and of permanent magnets — two phenomena that can produce only very weak forces when operating individually. Some day perhaps we will learn enough to apply gravitational forces in the same way we have learned to apply electromagnetic forces. This will depend upon advances in many fields of science. Some of the things required will be enormously increased sources of power from atomic fusion; very intense magnetic fields and current densities, perhaps from superconducting sources; and extremely strong materials to contain mechanical forces. Some of these advances are approaching, or are on the horizon. Others we have yet to see clearly. May I close this part of our discussion by recalling the statement that the most important secret of the atomic bomb was that it worked. This gave the crucial impetus to other nations in their own efforts to duplicate the research of the United States. In the UFO phenomena we have demonstrations of scientific secrets we do not know ourselves. It would be a mistake, it seems to me, to ignore their existence. I have further comments on UFO’s and high-strength materials, but perhaps the committee would rather interrupt at this point before I go on to that second subject? Mr. Roush. Any questions? I think you better go ahead, Dr. Harder, because if we get started questioning it is impossible to stop these people. Mr. Boone. Mr. Chairman, may I ask one question? Mr. Roush. Go ahead, Mr. Boone. Mr. Boone. Have you concluded that what you have just told us is true, we should not ignore their existence? Dr. Harder. I have no doubt of the veracity of the observer who saw this thing in the sky; I know him personally. Mr. Boone. I didn’t question the observer, I questioned your remark, and the magnetic, if you will, electromagnetic interactions, and so forth, when you said we undoubtedly must admit the existence of these — I am sorry I can’t quote you exactly. But your last sentence there is what I refer to. It does seem like an obvious conclusion resulting from all the previous remarks you said about some supernatural, if you will — Dr. Harder. Oh, heavens, I never suggested that, I hope. Mr. Boone. Well, let me say, science fiction propulsion system, then. Dr. Harder. Well, sir, what we have been discussing this morning, and this afternoon, is perhaps closer to science fiction than anything. I hope it is more science than fiction, however. Mr. Roush:. Go ahead, Dr. Harder. Dr. Harder. The instances in which physical fragments of UFO’s have been found are disappointingly few. To my knowledge, there is only one well-authenticated finding, and that was in Brazil, in

[[119]]

1957. The story of its discovery is contained in chapter 9 of the Great Flying Saucer Hoax, written by Dr. Olavo T. Fontes. Briefly, several small metallic fragments were recovered by some fishermen near the coastal town of Ubatuba, Sao Paulo, after they saw what they described as a brilliant explosion of a flying disc. Some of the fiery fragments were extinguished in the water near the shore, where they were recovered. Fontes acquired three of the fragments that weighed less than a tenth of an ounce each, and had one of them analyzed at the Mineral Production Laboratory in the Brazilian Agriculture Ministry. The results of the first analysis was that the substance was magnesium of an unusually high degree of purity, and that there was an absence of any other metallic element. On the basis of the first examination a second spectrographic test was conducted, using the utmost care and the most modern instruments. The second report was again marked by references to the “extreme purity” of the sample. Even impurities that are sometimes detected due to contamination from the carbon rod used as an electrode were absent. A further test, using X-ray diffraction, failed to turn up any other metallic component. One of the pieces was flown to California and was analyzed. I have the report here. They used neutron activation analysis and discovered a total of one-tenth of 1 percent of other metallic elements than magnesium, 500 parts per million zinc, that included zinc, which is interesting, and small amounts of barium and strontium. Certainly this metal is of extraordinary purity, certainly far beyond the capacity of fishermen at Ubatuba to produce. What could be the use of such high-purity magnesium in the context of a spacecraft? One clue lies in its crystalline structure. It is close packed hexagonal structure, and is in this regard similar to the high-strength metals beryllium and titanium. Hexagonal crystals have but one slip plane, and this tends to make them brittle but strong. One of the reasons for slip along crystal planes is that local imperfections in the crystal, or foreign atoms, create lines of stress concentration that move rapidly through the crystal, producing deformation. If these imperfections, or dislocations, could be eliminated, the theoretical strength of the crystal lattice itself might be approached. This strength is on the order of millions of pounds per square inch for any materials. Carefully prepared 1/4-inch diameter glass rods, etched to remove microscopic surface cracks and then lacquered, have withstood stress of 250,000 psi for i hour. Fused silica fibers have been stressed to 2 million psi. Thus, foreign atoms within a crystal lattice are focal points for dislocations — points of stress concentration where the crystal lattice itself tears and slips. We can imagine that a high-purity crystal, free of surface and internal imperfections, would achieve fantastic strengths. Indeed, with the advent of iron whiskers, and boron fiber reinforced composites, we are already approaching some of these strengths, but only for extremely small diameter fibers. Should, by any good fortune, further samples of UFO material be found, there may be further clues that would spur on research into high-strength materials, and perhaps give us hints of how to achieve

[[120]]

superstrength in materials that are larger than the tiny fibers we have produced so far. Needless to say, if we persist in denying the reality of UFO s we will not be looking for such samples, and may indeed reject them as having no importance when they are brought to our attention. That is the conclusion of my prepared statement. I would like to comment on some of the suggestions as asked by Congressman Rumsfeld earlier. I conclude in some of my colleagues’ recommendations that a multiple-faceted exploration be made of this subject, preferably at several institutions simultaneously. I have some suggestions as to how we could acquire additional scientific data even at the present time. This is a three-point program which involves first the establishment of an early warning network, which the Colorado project began last February. Then to take advantage of one of the characteristics of UFO sightings: that they, in many instances, are seen on one or two successive nights. We could have prearranged instrument packages which are arranged for instant transportation to locations where UFO’s have been sighted. If the budget for such a program were low, you might be able to borrow such things and have them ready at various universities where the instruments were otherwise occupied for research. That would be the second point of this investigation. The third point would be the cooperation of the Air Force for logistics and high-speed transport to crucial areas on a 24-hour basis. Now, that three-point program may well bring to us physical data that so far has appeared only in anecdotal, still from essential amateurs who happened just accidentally to be at the right place. It was truly a fortunate accident when Mr. Webb was there to make the observation I described earlier. Mr. Roush. Does that conclude your statement? Dr. Harder. That concludes my statement.

PREPARED STATEMENT OF DR. JAMES A. HARDER

I am very glad for this opportunity to present to your Committee some of my views on the problem of Unidentified Flying Objects and to indicate some of the areas in which I think a closer investigation of this problem might provide us with scientific clues that would give an important impetus to basic and applied research in the United States. There have been strong feelings aroused about UFO’s, particularly about the extra-terrestrial hypothesis for their origin. This is entirely understandable, in view of man’s historic record of considering himself the central figure in the natural scene; the extra-terrestrial hypothesis tends inevitably to undermine the collective ego of the human race. These feelings have no place in the scientific assessment of facts, but I confess that they have at times affected me. Over the past twenty years a vast amount of evidence has been accumulating that bears on the existence of UFO’s. Most of this is little known to the general public or to most scientists. But on the basis of the data and ordinary rules of evidence, as would be applied in civil or criminal courts, the physical reality of UFO’s has been proved beyond a reasonable doubt. With some effort, we can accept this on an intellectual level but find a difficulty in accepting it on an emotional level, in such a way that the facts give a feeling of reality. In this respect, we might recall the attitude many of us have towards our own deaths: We accept the facts intellectually, but find it difficult to accept them emotionally. Indeed, there are flying saucer cultists who are as enthusiastic as they are naive about UFO’s — who see in them some Messianic symbols — they have a

[[121]]

counterpart in those individuals who exhibit a morbid preoccupation with death. Most of the rest of us don’t like to think or hear about it. This, it seems to me, accurately reflects many of our attitudes towards the reality of UFO’s — natural, and somewhat healthy, but not scientific. In my remaining statements, you will note that I have tacitly assumed the reality of UFO’s as a hypothesis underlying my assessment of the importance of this subject for scientific study.

I. THE UFO PROPULSION PROBLEM

By way of introducing the propulsion problem of UFO’s, I will review a sighting near the City of Corning in northern California during the night of August 13, 1960, by two California. Highway patrolmen. During that night and several succeeding nights there were many reports of UFO’s over northern California, but this particular event is important not only because of the fact that it has been well authenticated (see Appendix I p. 114) but because of the relatively long time and close nature of the observations. My condensed description that follows is from the official report filed the next day by the two officers (see Appendix II p. 114); from a half-hour taped interview conducted three days later by myself and Dr. Carl Johannessen of the University of Oregon; from a letter written by Officer Charles A. Carson to Walter N. Webb (Charles Hayden Planetarium, Boston, Massachusetts) dated November 14, 1960; and from a telephoned interview conducted by Dr. James McDonald with Mr. Carson on October 27, 1966. Officers Scott (Stanley E. Scott) and Carson (Charles A. Carson) were searching for a speeding motorcyclist along Hoag Road, east of Corning, California, between U.S. Highway 99W and 99E, when they saw what at first appeared to be a huge airliner dropping from the sky. This was at 11:50 p.m. They stopped and leaped from the patrol car in order to get a position on what they were sure was going to be an airplane crash. From their position outside the car the first thing they noticed was an absolute silence. Still assuming it to be an aircraft with power off, they continued to watch until the object was probably within one hundred to two hundred feet off the ground, whereupon it suddenly reversed completely, traveling at high speed back up the 45 degree glide path it had been taking, and gaining about 500 feet altitude. This observation was from a distance of one-half to one mile. They said it was about the size of a DC-6 without wings; Officer Carson later made a sketch which shows an elliptical object 150 feet long and 40 feet high. It was a very clear night, with no clouds, and as the object hovered for about a minute they got a good look at it. It was obviously not an aircraft of any design familiar to them, they said. It was surrounded by a white glow, making the object visible. At each end there were definite red lights, and at times five white lights were visible between the two red lights. They called the night dispatching office at the County Sheriff’s Office and asked that other cars be sent, and that all other cars in the area be alerted. The object then drifted westward towards them, losing altitude, and got within some 150 yards of them (“easy pistol range”) before drifting eastward again. During this time it performed “aerial feats” that seemed unbelievable: It was capable of moving in any direction — up, down, back and forth. At times the movement was very slow, and at times completely motionless. It could move at extremely high speeds, and several times they watched it change directions or reverse itself while moving at unbelievable speeds. As the object moved away from them towards the east, they followed at a judicial [sic] distance, encouraged by the expectation that they were to be joined by other officers. At that time they also radioed the Tehama County Sheriffs Office requesting that they contact the local radar base. By telephone the radar operator confirmed the UFO and stated that it was unidentified. (Note: The two officers drove the next day to the local radar base, were refused permission to talk to the radar operator that had been on duty, and were given what Carson described as the “ice water treatment” by the commanding officer.) There follow many interesting details of their hide-and-seek chase with the object over the next two hours. However, when we restrict our attention to the propulsion problem, the significant facts are: (1) there was no observable noise, (2) the UFO could hover (“seemed to float as if it were in water”) and move in any direction without altering its orientation, (3) it could sustain very high accelerations and move very rapidly, (4) it was able to hover or to move relatively slowly for at least two hours under circumstances that precluded suspension by aerodynamic lift forces.

[[122]]

What can we learn about the propulsion of UFO’s from the information provided by the observations of these two police officers? Mainly, it is negative information: From the silence it seems impossible that it could have been supported by a jet or rocket reaction. There are further considerations involving specific impulse, energy, etc., that we need not go into here, that provide compelling arguments against any conventional way of counteracting the earth’s gravitational field. There remains a slight possibility of developing sufficient reactive force by expelling relativistic neutrinos, for they would not be intercepted by the earth under a UFO and would not be noticed. Expelling neutrons would have this same advantage, but in the quantities required they would induce far more radioactivity than has ever been measured at sites where UFO’s have come close to the ground or have been reported to have landed. Fortunately, there has been at least one observation that tends to provide a bit of positive information. Mr. Wells Allen Webb, an applied chemist with a master of science degree from the University of California, was one mile north of Spain Flying Field, seven miles east of Yuma, Arizona, just off U.S. Highway 80, when his attention was drawn to the sky to the north by some low-flying jet aircraft. Then he noticed a small white cloud-like object in an otherwise cloudless sky. He watched for about five minutes as it traveled eastward; as it reached a spot north northeast of his location, it abruptly altered shape from being oblong and subtending about half the angle of the full moon (about 15 minutes of arc) to being circular and subtending about 5 minutes of arc. Webb was wearing polaroid glasses, and noted that there appeared around the object a series of dark rings, the outermost of which was about six times the diameter of the central white or silvery object, or about the diameter of the full moon. The object or cloud then decreased in apparent diameter, as if it were traveling away from him, and disappeared in another few minutes. During this time Webb repeatedly took off his glasses and then put them back on, noting each time that the rings appeared only when he was wearing the glasses. He did not know what to make of the sighting, but took notes, including the fact that it was about 10 in the morning. The date: 5 May 1953. One of the first things to note about the situation as described in the account is that the dark rings were observed with polaroid glasses, but not without them. The second thing is that from the orientation of the observer relative to the position of the sun at that time of day, the blue scattered light from the part of the sky that formed the background for the object was polarized. To this fortunate circumstance we must add the fact that Mr. Webb was curious about clouds, the effect of viewing them with polarized light, and took notes of what he observed. He did not, however, realize that he was observing the rotation of the plane of polarization of the blue light in the vicinity of the object. This was the interpretation I made some ten years later upon reading his account. We can assume, to begin with, that the plane of the polarizer in his glasses was parallel to the plane of the undisturbed polarized light from the general direction of the object. If then something affected the light so as to turn its plane of polarization through 90 degrees, the portion that had been originally polarized would not pass through the glasses. Likewise, for light that had had its plane of polarization turned through 90 plus 180 degrees, 90 plus 360 degrees, and so on, there would be a partial extinction of light. On this basis, the outer dark ring was due to the rejection, by the polarizing filter of the glasses, of light which had had its plane of polarization turned through 90 degrees, the next outermost band by light that had been turned through 270 degrees, etc. This interpretation is strengthened by Webb’s observation that the dark rings were narrower than the brighter areas between them; this is what should be expected on the basis of the above explanation. What hypotheses can be constructed that might account for this unusual observation? There are at least two that have interesting implications for the propulsion problem. First, by the Faraday effect, a magnetic field parallel to the path of the light could so rotate the plane of polarization. A quick calculation using the properties of the atmosphere shows that a field of 200,000 gauss, operating over a distance of 130 feet (40 meters) could turn the plane 90 degrees; this is indeed a very intense and extensive magnetic field, and of course, would only account for one ring. Three rings would require a million gauss over the same distance. We have been able to achieve these field strengths in the laboratory for only fractions of seconds over very small distances. However, the principal argument against this hypothesis is the conclusion that were such a field be brought at all close to the surface of the earth its effect would be to induce very strong

[[123]]

remnant magnetism in nearly every piece of iron within several hundred yards. This has not been found. Despite the above-described observation, there is little reason to believe that magnetic fields, of themselves, could be of much use in propelling a spacecraft, although there has been much uninformed speculation about this in popular UFO publications. The simple reason is that we cannot produce a north pole without at the same time producing a south pole. This is a consequence of fundamental theory. Such a dipole cannot exert a force in conjunction with a uniform magnetic field, such as the earth may be assumed to have in a given locality, though it can produce a force in a nonuniform field.

Gravitation remains one of the enigmas of modern science, although there have been some advances in its understanding (beyond general relativity) in the past decade. There are theoretical grounds based on general relativity for believing there must exist a second gravitational field, corresponding to the magnetic field in electromagnetic theory, and that the interaction between these two fields must be similar to that between the electric and magnetic fields. This kind of interaction and its exploitation forms the basis for our modern electrical generators and motors. Without the interaction, we would be back to the days of electrostatic attraction and of permanent magnets — two phenomena that can produce only very weak forces when operating individually. Someday perhaps, we will learn enough to apply gravitational forces in the same way we have learned to apply electromagnetic forces. This will depend upon advances in many fields of science: Some of the things required will be enormously increased sources of power from atomic fusion; very intense magnetic fields and current densities, perhaps from superconducting sources; and extremely strong materials to contain mechanical forces. Some of these advances are approaching, or are on the horizon. Others we have yet to see clearly. May I close this part of our discussion by recalling the statement that the most important secret of the atomic bomb was that it worked. This gave the crucial impetus to other nations in their own efforts to duplicate the research of the United States. In the UFO phenomena we have demonstrations of scientific secrets we do not know ourselves. It would be a mistake, it seems to me, to ignore their existence.

II. UFO’s AND HIGH-STRENGTH MATERIALS

The instances in which physical fragments of UFO’s have been found are disappointingly few. To my knowledge, there is only one well-authenticated finding, and that was in Brazil in 1957. The story of its discovery is contained in Chapter 9 of The Great Flying Saucer Hoax (Coral B. Lorenzen, The Willeam-Frederick Press, New York, 1962) written by Dr. Olavo T. Fontes. Briefly, several small metallic fragments were recovered by some fishermen near the coastal town of Ubatuba, Sao Paulo, after they saw what they described as a brilliant explosion of a flying disc. Some of the fiery fragments were extinguished in the water near the shore, where they were recovered. Fontes acquired three of the fragments that weighed less than a tenth of an ounce each, and had one of them analyzed at the Mineral Production Laboratory in the Brazilian Agricultural Ministry. The results of the first analysis was that the substance was magnesium of an unusually high degree of purity, and that there was an absence of any other metallic element (Lorenzen, ibid, p. 99). On the basis of the first examination a second spectrographic test was conducted, using the utmost care and the most modern instruments. The report was again marked by references to the “extreme purity” of the sample. Even impurities that are sometimes detected due to contamination from the carbon rod used as an electrode were absent. A further test, using X-ray diffraction, failed to turn up any other metallic component. What could be the use of such high-purity magnesium in the context of a spacecraft? One clue lies in its crystalline structure: It is close packed hexagonal, and is in this regard similar to the high-strength metals beryllium and titanium. Hexagonal crystals have but one slip plane, and this tends to make them brittle but strong. One of the reasons for slip along crystal planes is that

local imperfections in the crystal, or foreign atoms, create lines of stress concentration that move rapidly through the crystal, producing deformation. If these imperfections, or dislocations, could be eliminated, the theoretical strength of the crystal lattice itself might be approached. This strength is on the order of millions of pounds per square inch for many materials. Carefully prepared 1/4 inch diameter glass rods, etched to remove microscopic surface cracks and then lacquered, have withstood stresses of 250,000 psi for one hour (C. J. Phillips, American Scientist, v. 53, no. 1, p. 32). Fused silica fibers have been stressed to 2,000,000 psi. Thus, foreign atoms within a crystal lattice are focal points for dislocations — points of stress concentration where the crystal lattice itself tears and slips. We can imagine that a high-purity crystal, free of surface and internal imperfections, would achieve fantastic strengths. Indeed, with the advent of iron whiskers, and boron fiber reinforced composites, we are already approaching some of these strengths, but only for extremely small diameter fibers. Should, by any good fortune, further samples of UFO material be found, there may be further clues that would spur our research into high-strength materials, and perhaps give us hints of how to achieve super-strength in materials that are larger than the tiny fibers we have produced so far. Needless to say, if we persist in denying the reality of UFO’s, we will not be looking for such samples, and may indeed reject them as having no importance when they are brought to our attention. Mr. Roush. Are there questions? Well, if not, let’s go to our next participant. Our next participant is Dr. Robert M. L. Baker, Jr. Dr. Baker, again we recognize your own eminence in your field, and we are very happy to have you here as a participant in this symposium. You may proceed.
