In mid-1947, a United States Army Air Forces balloon crashed at a ranch near Roswell, New Mexico. Following wide initial interest in the crashed "flying disc", the US military stated that it was merely a conventional weather balloon. Interest subsequently waned until the late 1970s, when ufologists began promoting a variety of increasingly elaborate conspiracy theories, claiming that one or more alien spacecraft had crash-landed, and that the extraterrestrial occupants had been recovered by the military, who then engaged in a cover-up.
In the 1990s, the US military published two reports disclosing the true nature of the crashed object: a nuclear test surveillance balloon from Project Mogul. Nevertheless, the Roswell incident continues to be of interest in popular media, and conspiracy theories surrounding the event persist. Roswell has been described as "the world's most famous, most exhaustively investigated, and most thoroughly debunked UFO claim.

It is revealed that the Roswell Incident was actually the testing of a cutting-edge aircraft that utilized the anti-gravity engine provided by Da'at Yichud to the US government in order to turn the tide of the desperate war against the highly technological-advanced Nazis force.
The initial test was a failure since the aircraft crashed in Roswell and the government try to cover its up to prevent the Nazis to find out about the test. However, Super Spesh at that time managed to salvage a part of the anti-gravity technology during his conspiracy investigation about the supposed alien technology.
While the US tried to further the testing, the Nazis dropped the Atomic Bomb on New York forcing the US government to surrender and preventing them to acquire the perfect their chance to turn the tide of the war. As the result, the anti-gravity technology fell into the hand of the Nazis and they were trying to perfect the technology for years after the occupation.
In 1961, Super Spesh still keeps the salvaged part in his basement in his diner and shows its to BJ.
