- On May 24, 1989, in a live interview with investigative reporter George Knapp on KLAS-Las Vegas, Robert “Bob” Lazar took the first steps toward becoming one of the most influential (and controversial) figures in all of UFO lore. Concealing his identity and using the pseudonym “Dennis,” Lazar said that deep within an unconfirmed section of Area 51 called “S4,” he’d once worked on recovered extraterrestrial spacecraft for the US government.
