Roswell, New Mexico

For decades, a U.S. military installation located roughly 100 miles north of Las Vegas had been one of the worst-kept secrets on the planet. Area 51, known to UFO conspiracy theorists and aviation buffs who piece together the details of classified military spy plane prototypes, is a place whose existence the U.S. government long refused to acknowledge.
Recently declassified documents made repeated references to Area 51 and detailed how it was selected as a testing area by the CIA, the U.S. Air Force and defense contractor Lockheed because of its remote location.
Area 51 is the place where government researchers reverse-engineered captured alien spacecraft, tried to clone extraterrestrials, and filmed the fake moon landing in 1969 [The government, as you might expect, did not confirm any of that.
