CIA Memorandum on UFO Responsibility and Investigative Activity (1957)

This CIA document, released via the CIA Reading Room, is an internal memorandum framed around three questions concerning UFOs, using the answers as sub-headings. It draws heavily on the recollection of CIA officer Phil Strong. The memo describes how, in the summer of 1952, CIA's Office of Scientific Intelligence (OSI) formed a scientific panel to study UFOs. Named participants include panel chairman H.P. Robertson of Cal Tech, Luis Alvarez (physicist at Berkeley), Thornton Page of Johns Hopkins University, and a Brookhaven National Laboratory physics chairman, among others associated with the President's Scientific Advisory Committee (ODM). The panel's report was completed on 17 January 1953, found to be thorough, and distributed to the Intelligence Advisory Committee (IAC). After the study, OSI maintained a watching process on UFO reports, routing natural-phenomena cases to the Geo-Physics Unit of the Fundamental Sciences Division and hardware/flying-craft cases to the Applied Science Division. The Air Technical Intelligence Center (ATIC) is described as maintaining one or two officers on the question — the remnant of the larger Air Force Project 'Blue Book,' with an attached project report dated 5 May 1955. The memo addresses whether the unexplained category could include secret Soviet advanced aeronautical equipment (answer: 'conceivably, yes') and states there was no special collection against UFO targets, though radical aeronautical designs were a high-priority collection requirement. It further reports that the British and Canadians (via the jointly owned firm 'Avro') had completed the design of a saucer-shaped aircraft with jets on the circumference, said to operate at 50,000 feet or better.

Description

A CIA internal memorandum, apparently dated 1957, responding to three questions about UFOs: whether follow-up responsibility had transferred from the Air Force to CIA, what CIA was doing on UFOs, and related collection activity. It recounts the 1952 formation and January 1953 conclusion of an Office of Scientific Intelligence (OSI) study panel (the Robertson Panel), the status of the Air Force's Project Blue Book, and reports of a British/Canadian (Avro) flying-saucer aircraft project.

Claims

  • After the study, OSI maintained a watching brief, routing natural-phenomena UFO reports to the Geo-Physics Unit and hardware/flying-craft reports to the Applied Science Division.

    75%
  • There was no dedicated collection against UFO targets, but radical Soviet aeronautical design advances were a high-priority collection requirement.

    75%
  • H.P. Robertson, Luis Alvarez, and Thornton Page were among the members of the scientific UFO panel.

    75%
  • ATIC retained only one or two officers on the UFO question, described as all that remained of the larger Air Force 'Blue Book' project.

    70%

    70%
  • ATIC maintained only one or two officers on the UFO question, the remnant of the larger Air Force Project Blue Book.

    70%
  • CIA conducted no special collection against UFO targets, though radical Soviet aeronautical designs were a high-priority collection requirement.

    70%
  • The British and Canadians (via Avro) had completed the design of a flying-saucer aircraft with jets on the circumference, intended for operation at 50,000 feet or higher.

    65%
