Bob Lazar
Says he was an S4 propulsion engineer, 1988 to 1989
“I’m increasingly convinced that there’s another force of nature.”
Bob Lazar is the man who, in a 1989 KLAS-TV interview with George Knapp, first put “Area 51” and “Element 115” into public discourse. He said he had reverse-engineered the propulsion of a recovered extraterrestrial craft at a facility called S4, south of Area 51. His account introduced three of the subject’s most durable terms, Area 51, Element 115 and the Sport Model, and it has been argued over ever since. His account runs from claims that rest on his own testimony, the craft and the S4 projects, to a credential history that the documentary record disputes.
Who he is
Lazar says he worked in 1988 and 1989 at S4, a facility near Papoose Lake adjacent to Area 51, on the reverse-engineering of recovered extraterrestrial craft, specifically their propulsion, under the project codename Galileo. He first made the claim publicly in the 1989 KLAS-TV interview with George Knapp. Over thirty-seven years his core account has stayed broadly stable while details have shifted, most notably his 2026 retraction of the word “gravity” in favour of an unidentified force; DEBRIEFED ep. 83 and the parallel American Alchemy interviews in 2026 both carry that revision.
Lazar says he holds degrees from the Massachusetts Institute of Technology and the California Institute of Technology and worked at the Los Alamos National Laboratory before S4. No records of those degrees have been found, and his academic and employment credentials are widely disputed. Lazar says his records were erased. The claim, the documented absence and his explanation are all on the record.
What he says
The Sport Model. He describes a roughly 53-foot, seamless, dark-metallic disc with three seats around a central reactor. He says the hull behaves like an electret, permanently storing a high DC potential, and that during liftoff light bends around the craft, making it invisible from directly beneath.
“As I walked out under the craft, I couldn’t see the craft. As I got closer to it, the craft just turned into sky.”
Element 115 / Moscovium. He says the reactor was fuelled by a stable isotope of element 115, and that X-rays showed an internal mini-cyclotron bombarding the 115 target to produce a directional, controllable force field. Element 115 was synthesised in 2003 and named Moscovium; the isotopes produced so far have lasted milliseconds.
The three S4 projects. He describes three programmes: Galileo, propulsion, his own, to duplicate the system and learn to disable it remotely; Sidekick, weaponisation; and Looking Glass, time distortion, which he says produced minor time-flow effects from its gravitational field.
The nine craft. He says that through open bay doors he saw nine distinct craft at S4, most non-disc, including a “Jell-O mold” and a “carnival hat” with a hole punched up through its base. He cites a 2026 enhancement of 2022 Google Earth imagery of the Papoose Lake site that he says shows nine rectangular anomalies matching his nine-hangar description. Independent analysts have offered alternative readings of the imagery, citing geology and image artefacts.
“It’s not gravity”, the 2026 update. In 1989 and 2018 he called the S4 effect “gravity” for want of a better word. In 2026 he revised this:
“I’m not even sure it’s gravity. As time goes on, I’m increasingly convinced that there’s another force of nature.”
He says his reasoning is that gravity should be purely attractive, whereas the S4 effect repelled matter, selectively bent light, and froze kinetic energy without crushing the object, none of which he says fits ordinary gravitational physics.
On whether he saw an alien. He says he did not.
“I looked in there and there were just some guys in lab coats looking down at one of the seats. And I think they had a mannequin or something in there. I don’t believe there was any aliens around there.”
He says he saw drawings of bodies in briefing documents, describing one fused organ in the chest cavity and an attribution to Zeta Reticuli, but adds that he was told the briefings contained deliberate, per-reader disinformation to catch leaks.
The retrieval. He cites a colleague on where the craft came from.
“Barry told me the sport model was retrieved by the Navy from an ‘archaeological dig’ that was ‘in the water, not the desert.’”
In his own words
“Nothing has any human marks on it. There’s nothing superfluous. Everything there has a specific function.” “We call this antigravity because there’s nothing else to call it. But I think there’s another force that we haven’t discovered. And that’s what this machine is taking advantage of.” “Look, if you can produce gravity, if you can control gravity, you already rule the world.” “I’m increasingly convinced that there’s another force of nature.”
What is on the record
Element 115 was synthesised in 2003 and named Moscovium; this is on the record. The isotopes made so far have lasted milliseconds rather than the stability Lazar describes; no long-lived, stable isotope has been produced. Lazar’s degrees from MIT and Caltech and his employment at Los Alamos are not supported by any located records and are widely disputed; he says his records were erased. The S4 facility, the projects, the nine craft and the retrieval are described in his testimony; they are not public record. The Papoose Lake imagery he cites is contested, with analysts offering geological and image-processing readings. The rolling PURSUE declassification is the channel in which claims of this kind either appear in the record or do not, and the document briefings on this site read each release as it comes.
