This document is a 1958 Air Force briefing to a Congressional Subcommittee detailing the history, methodology, and conclusions of the Air Force's UFO investigation program. The Air Force concluded that UFOs pose no national security threat and recommended de-emphasizing the program to reduce public anxiety.
This document is a transcript and supporting memorandum for an Air Force briefing provided to the Subcommittee on Atmospheric Phenomena of the House Select Committee on Astronautics and Space Exploration on August 8, 1958. The briefing was requested by the Subcommittee to review the history and procedures of the Air Force's UFO program. Representatives from the Air Technical Intelligence Center (ATIC), including Mr. A. F. Arcier and Captain George Gregory, presented the history of the program, which began in 1947 with 'Project SIGN,' followed by 'Project GRUDGE,' and eventually 'Project BLUE BOOK.' The briefing detailed the Air Force's efforts to apply scientific analysis to UFO reports, noting that the percentage of 'unknown' sightings had been reduced to approximately 3 percent. The Air Force stressed that UFOs do not constitute a threat to the security of the United States and that the Air Force has never suppressed evidence regarding them. The briefing also addressed the rise of private UFO organizations, which the Air Force characterized as a source of 'spectacular news reporting' and 'unwarranted anxiety.' The Air Force outlined its procedures for investigation, including the use of the 4602d Air Intelligence Services Squadron for field investigations and the use of 'Videon' cameras to analyze light components. The document references Project BLUE BOOK Report No. 14, which concluded that there was no evidence that UFOs were interplanetary spacecraft or technological developments beyond current scientific knowledge. The briefing concluded with the recommendation that the UFO program be de-emphasized to avoid interfering with the normal mission of the Air Defense Command and to strip the subject of its 'air of mystery' in the public mind. The Subcommittee members expressed satisfaction with the Air Force's approach and indicated that no further formal hearings were required.
It was also stressed that the Air Force, contrary to claims of many professional UFO organizations, has not and will not suppress any evidence which would indicate that UFO's constitute a threat to the security of the United States.
