On 20 June 1958 U.S. Air Force officers briefed Representative John E. Henderson of Ohio and several of his colleagues in the Capitol on the Air Force's UFO program. A memorandum for the record noted their agreement that it would be unwise to give the subject undue publicity, especially through formal congressional hearings.[1][2]
Background

Members of Congress were receiving many letters from constituents about UFOs, particularly after the large wave of sightings in November 1957 and the publication of former Project Blue Book chief Edward Ruppelt's book The Report on Unidentified Flying Objects. Henderson had submitted questions they could not answer.[1]
The briefing

The briefing was given by Major Boland of the Air Force's legislative liaison office and Major Tacker of its information services, with technical help from Mr. Arcier and Major Byrne of Air Force intelligence. They described Project Blue Book as a continuous Air Force project, said 2,764 reports had been received since 1953, discussed radar and photographic evidence and the use of scientific experts, and handed out briefing kits with statistics, charts and case histories. The Air Force's position was that nearly all reports were misidentified aircraft, balloons, astronomical objects and hoaxes, and that the remaining unknowns showed no threat.[1]
Outcome
According to the memorandum, dated 23 June 1958, the members expressed confidence in the Air Force's handling of the program and agreed that public hearings would be unwise. It recommended drawing the Air Force's semi-annual UFO report to the attention of Senator Leverett Saltonstall and Henderson to counter what it saw as a campaign pressuring the Air Force.[1]
Context

The briefing was one of several in 1958, including sessions for the McClellan and McCormack subcommittees, that the Air Force used to head off congressional hearings sought by NICAP. The documents show how the Air Force managed congressional interest in the late 1950s.[2][3]
