Those who worked at Area 51 have now been released from their pledge of secrecy and, unfortunately for UFO buffs, their story is one of a CIA Black Op to test spy planes, not a coverup of dead aliens:
About the aliens.
Noce and Barnes say they never saw anything connected to UFOs.
Barnes believes the Air Force and the "Agency" didn't mind the stories about alien spacecraft. They helped cover up the secret planes that were being tested.
On one occasion, he remembers, when the first jets were being tested at what Muroc Army Air Field, later renamed Edwards Air Force Base, a test pilot put on a gorilla mask and flew upside down beside a private pilot.
Of course this is April Fool's Day. Just sayin'.
