The Lockheed SR-71 Blackbird (shown here in model kit form)
was one of the real UFOs at Area 51.
"In the 1960s, Area 51 was the test site for the A-12 and its successor, the SR-71 Blackbird, a secret spy plane that broke records at documented speeds that still have been unmatched...
But after September 2007, when the CIA displayed an A-12 in front of its Langley, Va., headquarters as part of the agency's 60th birthday, much of the secrecy of those days at Area 51 fell away."
