In 1952 Hollywood producer Clarence Greene saw an unusual object twisting in the sky. He decided to report the sighting, and contacted US Air Force public information officer Albert M. Chop, who was in charge of answering UFO questions from reporters and the public. Intrigued by his experience, Greene decided to film a documentary movie about the UFO Sightings phenomenon. When Chop told Greene about the existence of video footage of UFOs, Greene obtained the footage for analysis and display in his documentary.
The documentary starts in 1947, with the first widely-publicized UFO sightings in the United States, including recreations of the Kenneth Arnold UFO sighting, the Mantell UFO incident, and the Gorman Dogfight. It then traces the development of UFOs as both a popular fad and a serious concern for the US Air Force. The history of Project Sign, the first Air Force study of the UFO phenomenon, is discussed. The documentary then focuses upon Albert M. Chop and his growing involvement with UFOs. Chop is assigned as the public information officer at Wright-Patterson Air Force Base in Dayton, Ohio, in the late 1940s. In that position he is required to answer numerous news media queries about UFO sightings and what the Air Force knows about them. Although he is initially portrayed as a UFO debunker, Chop gradually changes his views as the movie progresses, and he comes to believe that UFOs are unknown, and possibly extraterrestrial, aircraft. By 1952 Chop has moved to Washington, DC, where he is the press officer for Project Blue Book. The documentary analyzes two famous pieces of UFO footage: the Mariana UFO Incident of 1950, in which the manager of the Great Falls, Montana minor-league baseball team claimed to have filmed two UFOs flying over the baseball stadium, and the 1952 UFO film taken near the Great Salt Lake in Utah by a US Navy photographer, Delbert Newhouse. The documentary concludes with the famous 1952 Washington DC UFO incident, in which Albert Chop played a central role. The documentary recreates Chop's experiences during the incident, and at the end of the documentary Chop states his belief that UFOs are a "real", physical phenomenon of unknown origin. credit Frank Stalter
