S-4 (sometimes "Sector Four") is the name of a secret facility near Papoose Lake, south of Groom Lake (Area 51) in Nevada, where Bob Lazar claimed in 1989 that he had worked on reverse-engineering alien spacecraft. No evidence has been found that the facility exists.[1][2]
Lazar's account

Lazar said that S-4 was built into the side of a mountain beside Papoose Lake, with hangar doors disguised to match the slope, and that it held nine disc-shaped craft of different designs. He said he was employed there in 1988–1989 to study the propulsion system of one of the craft. His account, first broadcast by Las Vegas journalist George Knapp, made Area 51 famous worldwide.[1][2][3]

Papoose Lake lies within the restricted Nevada Test and Training Range, and visitors cannot approach it. Researchers who have studied satellite images and the surrounding area have found no sign of hangars in the mountainside, and no document has confirmed a facility called S-4 there. Skeptics also note that a real "Site 4" exists but is part of an electronic combat range near the Tonopah Test Range, more than 80 km (50 miles) to the northwest.[2][4]
Lazar's credibility
Lazar's broader claims, including his education at the Massachusetts Institute of Technology and Caltech, have been questioned because no records of his attendance have been found.[1][3]
