Area 51, located on Groom Lake in southern Nevada (c.), was founded in 1955 by the U.S. Air Force to develop and test new aircrafts such as the U-2 Spy Plane, A-12 Blackbird and F-117 Stealth Fighter. The secretive nature of the military base, combined with its classified aircraft research, helped conspiracy theorists imagine an installation filled with time-travel experimentation, UFO coverups and alien autopsies.
