Lazar has achieved notoriety as an Area 51 conspiracy theorist. In May 1989, he appeared in an interview with investigative reporter George Knapp on Las Vegas TV station KLAS, under the pseudonym "Dennis" and with his face hidden, to discuss his purported employment at "S-4", a subsidiary facility he claimed exists near the Nellis Air Force Base installation known as Area 51. He claims that the said facility was adjacent to Papoose Lake, which is located south of the main Area 51 facility at Groom Lake. He claimed the site consisted of concealed aircraft hangars built into a mountainside. Lazar said that his job was to help with the reverse engineering of one of nine flying saucers, which he alleged were extraterrestrial in origin. He claims one of the flying saucers, the one he coined the "Sport Model", was manufactured out of a metallic substance similar in appearance and touch to stainless steel. In a subsequent interview that November, Lazar appeared unmasked and under his own name, where he claimed that his job interview for work at the facility was contractor EG&G and his employer was the United States Navy; EG&G stated it had no records on him.
