I was worked at Foreign Technology Division HQ/IN, Wright Patterson AFB from 1988-1989.
My particular office was where Project Blue Book was run out of during the 1950’s-1960’s.
Project Blue Book was assigned to analyze all unidentified flying objects during that time.
I was cleaning out my old steel desk one day and a couple file folders had fallen behind the drawers. They were old PBB case files. They were by that time unclassified so I took them home and still have them in a box somewhere. The number of hoaxes was higher than the number of truly unidentified objects.
Around 1988, Fox ran a special documentary called Alien Autopsy, purporting to have originated at FTD, as part of our complex was the infamous Hangar 18 of UFO lore, where the original Roswell aliens were allegedly taken.
A congressman demanded that we prove this documentary was real or a hoax. So me and another analyst spent two days pouring over this documentary finding clues that showed that it was a complete fabrication. For example, all photos, documents, videos entering FTD were assigned FTD document numbers. Every document entering FTD went through my office first and we assigned the FTD numbers.
The numbers shown in the documentary were fictitious and didn’t even match our sequencing code.
As well, I’m one of not many people who has actually been in “Hangar 18”, which hadn’t used that designation in decades. It was iirc building 110. High security and need to know basis to enter, yes, but not because we were harboring alien skeletons, but because a railroad spur entered that building and certain equipment stolen, given etc., to the U.S., entered by train at night and was disassembled, studied and reverse engineered, if necessary, for our engineers.
Just as with Area 51, just because something is highly secretive, doesn’t mean the government is hiding it from you. They are highly sensitive military programs that require secrecy and remote locations.
