Area 51 is the common name of a highly classified United States Air Force (USAF) facility located within the Nevada Test and Training Range. The facility is officially called Homey Airport (KXTA) or Groom Lake, named after the salt flat situated next to its airfield.
The intense secrecy surrounding the base has made it the frequent subject of conspiracy theories and a central component of unidentified flying object (UFO) folklore.
