A newly declassified CIA history from 20 years ago spills the story about Nevada's Area 51 and its secret mission — which was not to study UFOs, but to test the U-2 and other spy planes.The CIA's story about the legendary test site is contained in "The Central Intelligence Agency and Overhead Reconnaissance: the U-2 and Oxcart Programs." The document was approved for release in June, with just a few remaining redactions, in response to a Freedom of Information request filed by George Washington University's National Security Archive back in 2005.
Much of the material was already known to Area 51 aficionados.

But the fact that Area 51 is explicitly mentioned in a publicly available document is nevertheless notable.
