Report of the Scientific Panel on Unidentified Flying Objects

This document, dated 18 February 1953, is a memorandum from the Intelligence Advisory Committee (IAC) regarding the findings of a scientific panel convened to evaluate Unidentified Flying Objects (UFOs). The panel, chaired by H. P. Robertson, reviewed evidence provided by the Air Technical Intelligence Center (ATIC), including 75 case histories from 1951-1952, various project reports (GRUDGE, BLUE BOOK, STORK, TWINKLE, FOURCE), and photographic and radar data. The panel concluded that there was no evidence that UFOs represented a direct physical threat to national security. However, they expressed significant concern that the continued reporting of these phenomena, and the 'special status' afforded to them, created a danger to the orderly functioning of protective organs. Specifically, the panel argued that the volume of reports clogged communication channels and fostered a 'morbid national psychology' that could be exploited by hostile propaganda to induce hysteria or distrust of authority. To mitigate these risks, the panel recommended that national security agencies take immediate steps to strip UFOs of their special status and implement an integrated program of intelligence, training, and public education to help the public and military personnel recognize and reject false indications of hostile action. The memorandum proposes that these findings be shared with the Secretary of Defense, the Director of the Federal Civil Defense Administration, and the Chairman of the National Security Resources Board, and concludes that no National Security Council Intelligence Directive on the subject is warranted.
