Robert Scott Lazar is an American conspiracy theorist who claims he was hired in the late 1980s to reverse-engineer extraterrestrial technology. This work supposedly occurred at a secret site called "S-4", a subsidiary installation allegedly located several kilometers south of the United States Air Force facility popularly known as Area 51.

Area 51 is the common name of a highly classified United States Air Force (USAF) facility within the Nevada Test and Training Range. A remote detachment administered by Edwards Air Force Base, the facility is officially called Homey Airport or Groom Lake. Details of its operations are not made public, but the USAF says that it is an open training range, and it is commonly thought to support the development and testing of experimental aircraft and weapons systems. The USAF and CIA acquired the site in 1955, primarily for flight testing the Lockheed U-2 aircraft.
