Briefing of Representative Henderson and Colleagues on the Air Force Unidentified Flying Object (UFO) Program

This document is a Memorandum for Record dated June 23, 1958, detailing a briefing provided to Representative John E. Henderson and several colleagues on June 20, 1958. The briefing was conducted by Major Boland (SAFLL) and Major Tacker (SAFIS), with technical assistance from Mr. Arcier and Major Byrne (AFCIN-X1A). The session was held in the Capitol chamber in response to a series of questions submitted by Representative Henderson regarding the Air Force's Unidentified Flying Object (UFO) program, specifically following the publication of Edward J. Ruppelt's book, 'The Report on Unidentified Flying Objects.' The memorandum notes that members of Congress were frequently contacted by constituents regarding UFOs, leading to professional embarrassment due to a lack of information. To address this, the Air Force prepared briefing kits containing statistical information, charts, and case histories. The briefing lasted the entire morning and was considered successful, with the audience expressing confidence in the Air Force's handling of the program and agreeing that the subject should not be given undue publicity, particularly in formal Congressional hearings. The document also includes detailed responses to specific questions posed by Representative Henderson, covering topics such as the status of Project Blue Book, the number of reports received (2,764 since 1953), the use of radar and photographic evidence, and the Air Force's reliance on scientific experts. It concludes by recommending that the 'Air Force Semi-Annual UFO Report' be brought to the attention of Senator Saltonstall and Representative Henderson to counter a perceived concerted campaign to pressure the Air Force regarding UFOs.
