American Alchemy / Jesse Michels ↗YouTube-hosted preview and player; not relicensedLazar says a facility built into the Papoose Range, south of Groom Lake, held nine recovered discs in hangars and that he worked on the propulsion of one in 1988–89. No public record of an S-4 site exists; the dry lake is real and lies inside the Nevada Test and Training Range.
Read the full account
Papoose Lake is a real dry lakebed about 15 km south of Groom Lake. The facility Lazar names "S-4" is not. He describes hangar doors set into the mountainside, nine saucer-shaped craft, and a briefing room where he read documents about the craft's origin.
The claim has been repeated by Lazar since 1989 and is supported in the interviews by his own testimony and by George Knapp's account of vetting him. It is contested by researchers who could not confirm his Los Alamos employment or MIT/Caltech education, and no other first-hand witness to S-4 appears in the interviews.
The record is therefore "contested": the geography is verifiable, the installation is one man's account.

What is claimed
Michels narrates Lazar's 1989 account: that he worked at a secret facility called S-4, just south of Area 51 in the Nevada desert, where his job was to reverse engineer craft.

Lazar says two jobs were on offer and he was placed in the second, at S-4 in the Papoose Lake area.
Lazar says S-4 had nine hangars, large enough to explain the long corridors he walked.
Lazar says the briefings at S-4 covered Project Galileo, the one he was assigned to, and also Looking Glass and Sidekick.
Lazar says he saw an American flag on the "sport model" craft on his first day at S-4 and that, as he understands it, the Navy got that craft.
Michels narrates that S-4's existence is still officially denied, and that a researcher used Google Earth's historical imagery to find a 2022 view of the area before it was blurred.
