Detail
In May 1989, self-described physicist Bob Lazar appeared under the pseudonym "Dennis" on KLAS-TV in Las Vegas, claiming he had worked at a facility designated S-4 near Area 51, tasked with reverse-engineering a recovered extraterrestrial craft. He described a propulsion system driven by gravity waves using an element then unknown to science (later associated in popular accounts with element 115, Moscovium). Investigative journalists partially verified his employment in the Area 51 corridor and his Navy records. Lazar has kept a consistent, technically detailed account for over 35 years, though his central claims remain independently unverified and highly contested.
