Correspondence Re Congressman Henderson Request to DOD for UFO Data and Statistics

This collection of documents details a 1958 congressional inquiry initiated by Congressman John E. Henderson of Ohio, who requested information from the Department of Defense regarding the status and findings of the Air Force's Project Blue Book. Prompted by his reading of Edward J. Ruppelt's book on the subject, Henderson submitted a series of questions to Secretary of Defense Neil H. McElroy. These questions covered the operational status of Project Blue Book, statistical data on UFO sightings since 1953, the classification of 'unknowns,' and inquiries into scientific efforts to track and analyze UFOs, including radar, photography, and radiation testing. The Air Force, specifically the Air Technical Intelligence Center (ATIC), responded by providing detailed answers and preparing a briefing for Congressman Henderson and his colleagues. The correspondence reveals the Air Force's internal strategy for managing congressional interest, which included hand-carrying briefings and providing statistical summaries to address the Congressman's concerns. A memorandum for the record dated June 23, 1958, describes a briefing held on June 20, 1958, for several members of Congress. The briefing was intended to provide a comprehensive overview of the UFO program, clarify the Air Force's investigative procedures, and address the skepticism of some attendees. The Air Force reported that the briefing was successful in fostering confidence in the program and securing an agreement that undue publicity, such as formal congressional hearings, would be unwise. Furthermore, the documents highlight the Air Force's concern regarding a perceived 'concerted, wide-scale campaign' to pressure Congress on UFO matters. The Air Force recommended that the 'Air Force Semi-Annual UFO Report' be shared with key legislators to counter this pressure. The documents also include technical notes on the Air Force's analysis methods, including the use of radar, theodolites, and spectrographic instruments, and reiterate the official stance that unexplained sightings are generally indeterminate spots of light rather than evidence of extraterrestrial craft. The materials underscore the tension between congressional oversight and the Air Force's desire to manage public perception and maintain control over the UFO narrative.
