Sources & Editorial Notes

George Knapp's original five-part investigative series for KLAS-TV Las Vegas. This is the foundational primary source: Lazar's first on-record disclosure of S-4, Element 115, and gravity-wave propulsion. All subsequent coverage derives from or responds to these broadcasts.

The earlier anonymous interview in which Lazar appears as "Dennis" — face obscured, voice altered — before agreeing to go fully on record. The first public airing of his account.

The only full-length written account authorized by Lazar. Covers his Los Alamos work, EG&G recruitment, S-4 assignment, technical observations, and the personal consequences of going public. The definitive primary source in Lazar's own words.

A three-hour unedited interview reaching tens of millions of listeners. Lazar gives his most technically detailed public account of his work at S-4 since the 1989 broadcasts. Widely cited as his most complete modern interview.

A W-2 employment record obtained by George Knapp referencing the U.S. Department of Naval Intelligence, corroborating Lazar's claim of government employment in the context he described. Referenced extensively in all serious credibility assessments.
