The Nazi Hypothesis is the theory that UFOs are secret weapons developed by the Third Reich and were moved at the end of the Second World War to Antarctica. Proponents claim that international Antarctic expeditions in 1946 and 1947 were actually searches for Hitler, who was thought to be alive, and his base. Current UFO sightings are explained as survey trips by Nazis in their flying saucers. The main promoters of this theme are a group in Toronto known as Samisdat, a faction of the neo-Nazi Western Guard. Their advertisement sin UFO magazines threaten that Nazis may one day take their revenge on the Allies with ‘UFO Power’. Some UFOlogists have suggested that the group is merely using UFOs as a means of promoting Nazi propaganda.
