Bob Lazar and the S-4 Claims

Robert "Bob" Lazar says that between December 1988 and April 1989 he worked a handful of days at a hidden site called S-4. He placed it beside Papoose dry lake, 10 to 15 miles south of Groom Lake. Area 51. His job, he said, was to reverse-engineer flying saucers that were not made on Earth. "I was involved mainly in propulsion and the power source."

Lazar described nine hangars built into a mountainside, disguised to look like the desert floor. Nine discs. About half working, the other half being torn down to analyze the components. The one he called the Sport Model was "a slim, thin disk with ridges in it." Roughly 30 to 40 feet across. About 15 feet tall. It felt like ordinary metal. Inside were really small chairs, and that detail convinced him no human had built it.

He said he saw it fly once, at close range. "The bottom of it glowed blue and began to hiss." It lifted off the ground quietly, slid over to the left, then back to the right, and set back down. He spoke of an antimatter reactor fuelled by element 115, and three gravity generators on the bottom.

The tests, Lazar said, were only done on Wednesday nights. On 22 March 1989 he drove out with his wife Tracy, Gene Huff and John Lear. They arrived at dusk, turned their lights off and went about 5 miles in on the Groom Lake road. Huff remembered a bright light rising above the mountains. It jumped and danced, doing step moves, then came to a dead stop and hovered. After a few minutes it slowly sat back down behind the mountains.

On 29 March they returned with a video camera, a telescope and binoculars. Jim Tagliani came along. This time, Huff said, the disc came down the mountain range toward them. "You'd blink and it would seem a lot closer." It glowed so brightly they moved behind the open trunk lid for protection. The tape shows a moving light, timestamped 8:30 PM. On 5 April security vehicles chased the group. A Lincoln County officer named LaMoreaux took their IDs and radioed their identities to the base.

15 May 1989. Lazar appeared on KLAS-TV in silhouette, under the name "Dennis." On 10 November he was named on air in George Knapp's series UFOs: The Best Evidence. KNPR later called it the highest rated, most-watched local news program ever produced in Las Vegas. KNPR also reports that Lazar easily passed a second polygraph test.

Almost none of Lazar's education or employment claims can be checked. MIT and Caltech have no record of him. In the years he claims to have been at MIT, he was attending Pierce Junior College. EG&G and Los Alamos say they have no records of him. A 1982 Los Alamos phone book does list him, but with a code marking a subcontractor. Element 115 was first made in 2003, and its isotopes decay in milliseconds. Tom Mahood cross-checked public records and rejected the idea that they had been wiped. Knapp and Jeremy Corbell maintain that they were. Even the desert accounts differ. Mahood's timeline says only Lear saw a light on 22 March, through a telescope.

Benjamin Radford wrote that almost nothing Lazar said was true, yet his "lies propelled Area 51 into the public's consciousness." A Testors model kit, Corbell's 2018 documentary and a 2019 appearance on the Joe Rogan Experience followed. That episode inspired the Storm Area 51 event, with more than 2 million people marked "going". In 2026, S4: The Bob Lazar Story rebuilt his world with CGI reconstructions.
