Area 51 is a secret Air Force base secluded deep within a wide-ranging tract of restricted government land in the remote Nevada desert. Generally believed to be the training and development zone for the military's most secret project, particularly spy planes and stealth technology, rumors of something more sinister taking place at Area 51 persist despite any compelling evidence.
Widespread speculation ranges about exactly what goes on at the base.
A number of people have reported strange sightings in the sky above the base, and others contend the military uses the base to study downed and captured alien craft, even aliens themselves, eventually using the alien technology in military projects. For the past several decades, the Air Force has officially denied the existence of Area 51, also known as the Groom Lake installation. But in a recent statement, it has admitted that something exists in the middle of the desert, but won't say what. We do have facilities within the complex near the dry lake bed of Groom Lake. The facilities of the Nellis Range Complex are used for testing and training technologies, operations, and systems critical to the effectiveness of U.S. military forces.
