After some investigation, Keyhoe became convinced that the flying saucers were real. As their forms, flight maneuvers, speeds and light technology was apparently far ahead of any nation's developments, Keyhoe became convinced that they must be the products of unearthly intelligences, and that the U.S. government was trying to suppress the whole truth about the subject. This conclusion was based especially on the response Keyhoe found when he quizzed various officials about flying saucers. He was told there was nothing to the subject, yet was simultaneously denied access to saucer-related documents.
