Person

Bob Lazar

The physicist who in 1989 told KLAS-TV's George Knapp he had worked on recovered alien craft at S-4, near Area 51, and the man who first made the base's secret activities public. He described the 'sport model' saucer, a gravity-amplifier propulsion system and a stable 'element 115' fuel. Critics have long attacked his education records; supporters point to his naval intelligence W-2 and Los Alamos listing. Jeremy Corbell's 2018 film Bob Lazar: Area 51 & Flying Saucers brought his story to a new generation.

Witness profile

On the record

Lazar's 1989 broadcasts with George Knapp.
In 2013 the CIA officially acknowledged Area 51, which Lazar named as the base for S-4 in 1989.
In June 2017 FBI agents raided United Nuclear, Lazar's company; the raid appears in Corbell's 2018 film.
A W-2 from the Department of Naval Intelligence and a phone listing at Los Alamos that Knapp obtained.

What Bob Lazar said (16 claims)

Witness testimony 10Alleged 4Does not hold 1

“Teller remembered him from Los Alamos and pointed him to EG&G and S-4.”Witness testimony48 hours with Bob Lazar and Luigi Vendittelli

The 1982 Los Alamos Monitor jet-car story is real; Teller, filmed later, refused to say if he knew Lazar.

“The sport model was found by the Navy in an underwater 'archaeological dig'.”Alleged48 hours with Bob Lazar and Luigi Vendittelli

New. Barry told him; never in the documents Lazar saw.

“His predecessor and others died when a team cut into a running reactor at the test site.”Alleged48 hours with Bob Lazar and Luigi Vendittelli

Told to him by Barry; told before.

“Nine hangars; he saw the sport model, a 'jello mold' and a 'top hat' with one hole shot up through its brim.”Witness testimony48 hours with Bob Lazar and Luigi Vendittelli

He saw three craft, not nine; corrects the film (one hole, not two).

“A candle flame froze, a black ball formed in the air and a watch stopped at the emitter's focus.”Witness testimony48 hours with Bob Lazar and Luigi Vendittelli

Firsthand; the watch test was left out of the film.

“The field is another force, not gravity.”Witness testimony48 hours with Bob Lazar and Luigi Vendittelli

His view now; says his own lab has results and he is '100% confident' he can duplicate it. Nothing shown.

“Element 115 was first made at Darmstadt.”Does not hold48 hours with Bob Lazar and Luigi Vendittelli

First made at Dubna (reported 2004); GSI Darmstadt confirmed it in 2013.

“A small American flag was stuck on the sport model.”Witness testimonyLazar's first UFO conference: Q&A with George Knapp

“Twenty-two people had clearance; he withholds the names as a test.”Witness testimonyLazar's first UFO conference: Q&A with George Knapp

“A craft shot with a projectile 'came out of the water'.”Witness testimonyLazar's first UFO conference: Q&A with George Knapp

In 2026 he tied an underwater dig to the sport model instead.

“About 500 lb of element 115 were on hand, with Los Alamos storing or shipping it.”AllegedLazar's first UFO conference: Q&A with George Knapp

“Only the sport model is certain; the others could have been holograms.”Witness testimonyLazar's first UFO conference: Q&A with George Knapp

“Edward Teller got Bob Lazar hired at S4 under EG&G.”Witness testimonyThe Manhattan Project 2.0 - the Secrecy of UFO Crash Retrieval Programs [VOL.1]

Lazar's own claim; Gerb discounts it.
