Robertson Panel 1953: no threat found, and a call to strip UFOs of their mystery

In January 1953 five scientists convened by the CIA reviewed the government's UFO evidence and found no indication of a direct physical threat to national security. Their two-page report urged that UFOs be stripped of their special status; the word "debunking" appears only in the unofficial minutes.

Why the CIA called in scientists

The panel grew out of a meeting of the Intelligence Advisory Committee on 4 December 1952. According to the minutes kept by Frederick C. Durant, the committee agreed that the Director of Central Intelligence would enlist selected scientists to review and appraise the available evidence in the light of pertinent scientific theories, and the task was delegated to the CIA's Assistant Director for Scientific Intelligence [4].

Five scientists signed the eventual report: H. P. Robertson of the California Institute of Technology as chairman, Luis W. Alvarez of the University of California, Lloyd V. Berkner of Associated Universities, Inc., S. A. Goudsmit of Brookhaven National Laboratories and Thornton Page of Johns Hopkins University [2]. Durant's minutes record eight sessions, from 9:30 a.m. on Wednesday, 14 January 1953, to the afternoon of Saturday, 17 January. Berkner was absent until the Friday afternoon session [4].

What the panel was shown

The list of evidence attached to the report begins with seventy-five case histories from 1951 and 1952, chosen by the Air Technical Intelligence Center as the best documented. It also includes the status reports of Projects GRUDGE and BLUE BOOK, the motion-picture films taken at Tremonton, Utah, on 2 July 1952 and at Great Falls, Montana, in August 1950, charts of balloon flight paths, a sample polyethylene balloon and a film of seagulls in bright sunlight [3].

On the first afternoon, Lt. R. S. Neasham and Harry Woo of the Navy's Photo Interpretation Laboratory at Anacostia presented their analysis of the two films, and Captain E. J. Ruppelt of ATIC spoke for about 40 minutes on how reports were handled and evaluated [4].

Tremonton: the Navy's analysts against the panel

Durant wrote that the Navy team had spent approximately 1,000 man-hours, at Air Force request, plotting individual frames of the Tremonton film. Its representatives concluded that the objects were not birds, balloons or aircraft, and, because they did not blink through 60 degrees of arc, that they were self-luminous [5].

The panel was impressed by the effort but could not accept the conclusions. Among its reasons, it noted that a semi-spherical object can reflect sunlight without blinking, and that the objects' motions, sizes and brightness strongly suggested birds, particularly after members watched a short film of seagulls [5]. The bird idea was not new: in October 1952 an ATIC officer had already proposed sending the original film to an ornithologist, perhaps at the Smithsonian, to judge whether the objects might be birds in flight [8].

It was the opinion of the P.I.L. representatives that the objects sighted were not birds, balloons or aircraft

The two-page report

The formal report, stamped 17 January 1953, says the panel received evidence from the intelligence agencies, mainly ATIC, and reviewed a selection of the best documented incidents. It concludes that the evidence showed no indication of a direct physical threat to national security, no residuum of cases attributable to foreign artifacts capable of hostile acts, and no need to revise current scientific concepts [1].

The danger the panel did see was indirect: channels of communication clogged by irrelevant reports, real indications of hostile action ignored after continued false alarms, and the cultivation of a morbid national psychology that hostile propaganda could exploit [1][2]. It recommended that the national security agencies strip UFOs of their special status, and that they institute policies on intelligence, training and public education, through an integrated program designed to reassure the public of the total lack of evidence of inimical forces behind the phenomena [2].

"Debunking" was in the minutes, not the report

Durant's memorandum of 16 February 1953 carried a second part: an unofficial supplement setting out comments and suggestions that panel members believed were inappropriate for the formal report [4]. That supplement describes a broad educational program with two major aims, training and "debunking". Training would teach service personnel to recognise balloons, aircraft reflections and natural phenomena; debunking would reduce public interest in flying saucers through television, motion pictures and popular articles built on solved cases. Members suggested psychologists, an advertising expert, the Jam Handy Co. and Walt Disney animated cartoons as possible help [6].

Popular accounts often quote the panel's report as recommending a national policy of "debunking"; the two-page report the five scientists signed never uses the word, which appears only in Durant's unofficial record of their side comments [2][6].

it should have two major aims: training and "debunking".

Distribution, secrecy and release

On 18 February 1953 the Intelligence Advisory Committee's secretary circulated the report, proposed sending copies to the Secretary of Defense, the Federal Civil Defense Administration and the National Security Resources Board, and recorded that the panel's work had moved CIA to conclude that no National Security Council Intelligence Directive on the subject was warranted [7]. The civil defense administrator, Val Peterson, replied that the recommendations, particularly on public education, were of considerable interest to the civil defense program [9].

The CIA's own history says officials later agreed that the Condon Committee could release the full Durant report with only minor deletions, and that in 1975, after William Spaulding of Ground Saucer Watch wrote on 7 June, the agency gave him copies of the panel report and the Durant report [10].
