You will not look up at the night sky the same as you use to after catching the New series episode's of Project Blue Book. This Government project was one of a series of systematic studies of unidentified flying objects (UFOs) conducted by the United States Air Force. It started in 1952, the third study of its kind, following projects Sign (1947) and Grudge (1949). A termination order was given for the study in December 1969, and all activity under its auspices officially ceased in January 1970. Project Blue Book had two goals: To determine if UFOs were a threat to national security, and To scientifically analyze UFO-related data. Thousands of UFO reports were collected, analyzed, and filed. As a result of the Condon Report (1968), which concluded there was nothing anomalous about UFOs, and a review of the report by the National Academy of Sciences, Project Blue Book was terminated in December 1969. The Air Force supplies the following summary of its investigations: No UFO reported, investigated, and evaluated by the Air Force was ever an indication of threat to our national security; There was no evidence submitted to or discovered by the Air Force that sightings categorized as "unidentified" represented technological developments or principles beyond the range of modern scientific knowledge; and There was no evidence indicating that sightings categorized as "unidentified" were extraterrestrial vehicles.
