Even before July 1969, he had "a hunch, an intuition, ... a true conviction" and decided that he did not believe that anyone was going to the Moon. Kaysing thus wrote a book titled We Never Went to the Moon: America's Thirty Billion Dollar Swindle, which was self-published in 1976, and republished by Health Research Books in 2002. In his book, Kaysing introduced arguments which he said proved the Moon landings were faked. Claims in the book including that: NASA lacked the technical expertise to put a man on the Moon. the absence of stars in lunar surface photographs was indicative of a hoax. there were unexplained optical anomalies in the photographs taken on the Moon. there was an absence of blast craters beneath the Lunar Modules, and that the rocket engines of the Lunar Modules should have generated an enormous dust cloud near their landing sites the final seconds of descent. the death of Thomas Baron, a quality control and safety inspector for North American Aviation, was mysterious and indicative of a hoax. He also noted that Dutch newspapers questioned the "authenticity" of the Moon landings. Charges of other conspiracies Kaysing also claimed that NASA staged both the Apollo 1 fire and the Space Shuttle Challenger accident, deliberately murdering the astronauts on board, suggesting that NASA might have learned that these astronauts were about to expose the conspiracy and needed to guarantee their silence. He also believed that the disappearance of Thomas Baron's 500-page report on the Apollo 1 fire and Baron's death in a rail-traffic accident a week after he testified before the United States Congress were not accidents. A vocal advocate of other conspiracy theories, Kaysing believed there to be a high-level conspiracy involving the Central Intelligence Agency, Federal Reserve, Internal Revenue Service and other government agencies to brainwash the American public, poison their food supply, and control the media.
