# Office Memorandum . UNITED STATES GOVERNMENT TO : MR. A. H. BELMONT FROM : V. P. KEAY DATE: July 29, 1952 SUBJECT: FLYING SAUCERS ## PURPOSE: To advise at the present time the Air Force has failed to arrive at any satisfactory conclusion in its research regarding numerous reports of flying saucers and flying discs sighted throughout the United States. ## DETAILS: Mr. N. W. Philcox, the Bureau's Air Force Liaison Representative, made arrangements through the office of Major General John A. Samford, Director of Air Intelligence, U.S. Air Force, to receive a briefing from Commander Randall Boyd of the Current Intelligence Branch, Estimates Division, Air Intelligence, regarding the present status of Air Intelligence research into the numerous reports regarding flying saucers and flying discs. Commander Boyd advised that Air Intelligence has set up at Wright Patterson Air Force Base, Ohio, the Air Technical Intelligence Center which has been established for the purpose of coordinating, correlating and making research into all reports regarding flying saucers and flying discs. He advised that Air Force research has indicated that the sightings of flying saucers goes back several centuries and that the number of sightings reported varies with the amount of publicity. He advised that immediately if publicity appears in newspapers, the number of sightings reported increases considerably and that citizens immediately call in reporting sightings which occurred several months previously. Commander Boyd stated that these reported sightings of flying saucers are placed into three classifications by Air Intelligence: (1) Those sightings which are reported by citizens who claim they have seen flying saucers from the ground. These sightings vary in description, color and speeds. Very little credence is given to these sightings inasmuch as in most instances they are believed to be imaginative or some explainable object which actually crossed through the sky. (2) Sightings reported by commercial or military pilots. These sightings are considered more credible
