Unidentified Flying Objects: The True Story of Flying Saucers

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 phenomenon. When Chop told Greene about the existence of film footage of UFOs, Greene obtained the footage for analysis and display in his documentary.
