Newly declassified documents reveal more detail about past use of the mysterious Nevada test site known as Area 51 and the concern for maintaining secrecy about the work done at the facility.
The recently released papers, which date mostly from the early 1960s into the 1970s, spotlight the U.S. government's desire for tight security at Area 51, also known as Groom Lake. The area was photographed with American reconnaissance assets to better assess what the Soviet Union's spy satellites might be able to discern.
The documents also detail the debate over the possible release of a photograph "inadvertently" taken of the secret facility by NASA astronauts aboard the Skylab space station in 1974. [Flying Saucers to Mind Control: 7 Declassified Military & CIA Secrets]
