The study of UFO's is a field that has been utterly infiltrated by the intelligence agencies, mostly due to the fact that UFOlogists keep going to secret weapon facilities and taking pictures. I still remember a UFO-documentary that involved the "researchers" driving out to a military base that wasn't on a map and (long story short) being told by the base PR officer that it was a chemical weapons facility, only to have them still yapping about aliens.
In multiple instances, the agencies have repeatedly spied or manipulated people working in this "field" in order to guarantee that no one accidentally gets pictures of real secret projects. One infamous incident involved a researcher being recruited by someone that we assume was involved in military intelligence, being flown out to actual secret government crash sites to document them, but then getting his mind slowly broken by being made paranoid from being actually spied on, and told weird lies to, and all sorts of other things until he killed himself.
