LAS VEGAS -- The CIA is acknowledging the existence of Area 51 in newly declassified documents.
George Washington University's National Security Archive obtained a CIA history of the U-2 spy plane program through a public records request and released it Thursday.
National Security Archive senior fellow Jeffrey Richelson reviewed the history in 2002, but all mentions of Area 51 had been redacted.
Richelson says he requested the history again in 2005 and received a version a few weeks ago with mentions of Area 51 restored.
But the newly released documents do not mention alien autopsies or spaceships crash landing on our planet, which will most likely disappoint many conspiracy theorists and true believers.
Officials have already acknowledged in passing the existence of the facility in central Nevada where the government is believed to test intelligence tools and weapons.
Richelson believes the new documents show the CIA is becoming less secretive about Area 51's existence, if not about what goes on there.
