CIA acknowledges its mysterious Area 51 test site for first time.
"Publicly released online on Thursday by the university's National Security Archive, the 400-page CIA history contains the first deliberate official references to Area 51, also known as Groom Lake, as a site developed by the intelligence agency in the 1950s to test fly the high-altitude U-2 reconnaissance plane.
Other top-secret aircraft were tested there later, including the supersonic reconnaissance A-12 aircraft, code-named OXCART, and the F-117 stealth ground-attack jet, said archive senior fellow Jeffrey Richelson, who asked for the CIA's U-2 history in 2005. A newly revised document restoring numerous references to Area 51 that had been redacted in earlier versions was furnished by the CIA a few weeks ago, he said.
"
It's the first time that there must have been a senior-level decision to acknowledge the term 'Area 51' and its specific location," he told Reuters on Friday."
