The Robertson Panel was a scientific committee which met in January 1953 headed by Howard P. Robertson. The Panel arose from a recommendation to the Intelligence Advisory Committee (IAC) in December 1952 from a Central Intelligence Agency (CIA) review of the U.S. Air Force investigation into unidentified flying objects, Project Blue Book. The CIA review itself was in response to widespread reports of unidentified flying objects, especially in the Washington, D.C. area during the summer of 1952.
The panel was briefed on U.S. military activities and intelligence; hence the report was originally classified Secret. Later declassified, the Robertson Panel's report concluded that UFOs were not a direct threat to national security, but could pose an indirect threat by overwhelming standard military communications due to public interest in the subject. Most UFO reports, they concluded, could be explained as misidentification of mundane aerial objects, and the remaining minority could, in all likelihood, be similarly explained with further study.
The Robertson Panel recommended that a public education campaign should be undertaken in order to reduce public interest in the subject, minimising the risk of swamping Air Defence systems with reports at critical times, and that civilian UFO groups should be monitored. The Robertson Panel's report was contained within a larger internal CIA report by F C Durant, a CIA officer who served as Secretary to the Panel, which summarises the activities of the panel and its conclusions. This wider document is commonly referred to as the Durant Report.
Background to the formation of the Robertson Panel
In 1952 there was a significant increase in the number of UFO reports received by the USAF Blue Book project, tasked with investigating such reports at the time. This wave included widely reported incidents over Washington DC in July, over the weekends of July 19-20 and 26-27. CIA historian Gerald Haines noted "A massive build-up of sightings over the United States in 1952, especially in July, alarmed the Truman administration. On 19 and 20 July, radar scopes at Washington National Airport and Andrews Air Force Base tracked mysterious blips. On 27 July, the blips reappeared. The Air Force scrambled interceptor aircraft to investigate, but they found nothing. The incidents, however, caused headlines across the country. The White House wanted to know what was happening ...". The reference to White House interest is consistent with a telephone call Captain (later Major) Edward Ruppelt, Blue Book Project Director at the time, received from Brigadier General Landry, Truman's military aide, on the July 28, inquiring as to the causes of the Washington reports of the previous days.
In a 29 July 1952 memo to the Deputy Director of Intelligence, Acting Assistant Director for Scientific Intelligence Ralph Clark commented; "In the past several weeks a number of radar and visual sightings of unidentified aerial objects have been reported. Although this office has maintained a continuing review of such reported sightings during the past three years, a special study group has been formed to review this subject to date. D/CI will participate in the study with D/SI and a report should be ready about 15 August." This is the earliest written record of the CIA study which led to the Robertson Panel.
The precise origins of the decision to establish the review are unclear. A claim that the study was initiated by a Presidential request to the National Security Council (NSC) appears to be incorrect. No NSC meetings were held on the relevant dates and the President was in Kansas on the 27 and 28 July, resting after attending the Democratic Party convention on the 26th. The Ralph L Clark memo of the 29th July contains a footnote reference to a meeting, "OSI:FCD:RLC mtw (28July52)" which appears to indicate a 28 July 1952 meeting between F C Durant and Clark on this subject. The decision to initiate the CIA study appears therefore to have been taken around July 28, although D/CI (Director of Central Intelligence) involvement in the study and Haines' reference to White House interest suggests that the FCD:RLC meeting was not itself the formal decision point. The decision appears to have been an operational decision taken outside of formal structures such as NSC meetings, as was common for urgent matters.
