# Office Memorandum • UNITED STATES GOVERNMENT TO DIRECTOR, FBI DATE: July 29, 1952 FROM : SAC, WASHINGTON FIELD 62-0 SUBJECT: AERIAL OBJECTS "Flying Saucers" INFORMATION CONCERNING On July 28, 1952, at the Weekly Intelligence Conference, Captain WILLIAM DEEGAN, Office of Special Investigations, 4th Air Force Base, Bolling Field, advised the representative of the FBI, Washington Field Office, over the prior weekend, his office had received reports concerning the observation of aerial objects. Captain DEEGAN referred to a phone call made to his office by Special Agent LEONARD E. WEBSTER of the Washington Field Office, furnishing to OSI the identity of a woman who reportedly had observed an aerial object. DEEGAN praised the WFO for the expeditious notification in this instance. Captain DEEGAN, Colonel COLLINS, DEEGAN's superior office, and Special Agent JOHN M. deBETTENCOURT, in a conference on July 28, 1952, discussed the matter of immediate notification of OSI. This conference resulted in the request by Colonel COLLINS and Captain DEEGAN that in the event, whenever information is received by the FBI, in which it is alleged that someone has observed a "Flying Saucer", this information be immediately relayed to Captain DEEGAN's office. It is to be noted that this office may be reached by dialing Code 1261 and asking for Extension 509. Captain DEEGAN said this number should be called under these circumstances at any time, day or night. Captain DEEGAN stated that the Air Force is greatly concerned about this matter of aerial objects and said that the Air Force Intelligence would appreciate the execution of the requested procedure, mentioned above. It is suggested that the Bureau bring this matter to the attention of its night supervisors, since these night supervisors also receive complaints from persons outside of the Bureau and may receive information concerning the observation of aerial objects.
