Dude, my pal worked at an old Warner Brothers soundstage in Burbank, a historical site, by the way, filming the moonwalk. He got paid plenty, enough to retire, and was sworn to secrecy, needless to say. Living somewhere in the Bahamas today, surrounded by babes and exotic fruits.
that is exactly how the government has kept the incident in Area 51 secret for so long.
Besides, anyone who has seen that old Gregory Peck/Gene Hackman movie Marooned knows that even the best film special effects available in 1969 couldn't convincingly fake space travel. (Marooned won the visual effects Oscar® that year).
