The Space Review: Astronauts and Area 51: the Skylab Incident

Far out in the Nevada desert, miles from prying eyes, is a secret Air Force facility that has been known by numerous names over the years. It has been called Paradise Ranch, Watertown Strip, Area 51, Dreamland, and Groom Lake. Groom is probably the most mythologized real location that few people have ever seen. According to people with overactive imaginations, it is where the United States government keeps dead aliens, clones them, and reverse-engineers their spacecraft. It is also where NASA filmed the faked Moon landings.

This secrecy was threatened in early 1974 when the astronauts on Skylab pointed their camera out the window and took pictures of a facility that did not officially exist. They returned to Earth and their photographs quickly became a headache for NASA, the CIA, and the Department of Defense. That story has never been told before.
