|Robert "Bob" Lazar|
Lazar claimed to have worked in 1988 and 1989 as a physicist at S4 allegedly located at Papoose Lake southwest of top secret Area 51 near Groom Dry Lake, Nevada. According to Lazar, S4 serves as a hidden military location for the study and research of extraterrestrial spacecraft, or flying saucers using reverse engineering. Lazar says he saw nine different extraterrestrial vehicles there and has provided detailed information on the mode of propulsion and other technical details of a disc-shaped vehicle he called the sport model.
