The great Otto Binder addressed the meaning of alleged symbols seen on UFOs in a 1972 article for Saga’s UFO Special magazine: Fate magazine presented, several decades ago, a piece on messages from alleged extraterrestrial beings that included this:
Lucius Farish (a true UFO investigator) along with Dale M. Titler wrote about symbols for Official UFO magazine (mid-70s) that included these representations:
The above symbols were either “photographed” on the UFOs or drawn by those who saw them on a UFO.
Why are there no such representations seen on UFOs purportedly flying overhead today?
Either the space aliens have become illiterate or the military has wised up and removed such designations from their prototypes.
