Estados Unidos, 1948: a Força Aérea manda coordenar investigações de discos com o FBI, que já tinha parado de investigar

CONFIDENTIAL [classification struck out]. Headquarters, Air Defense Command, Mitchel Air Force Base, New York. 4 February 1948. D 333.5 (CIB). SUBJECT: Investigation and Reporting of "Flying Disc" Incidents. TO: Commanding Generals, First, Second, Fourth, Tenth, Eleventh, and Fourteenth Air Forces, Air Defense Command. ATTN: AC of S, A-2. 1. The numbered air forces of this command are responsible for the prompt investigation and reporting of incidents relating to "flying discs" which occur within their respective areas. Numbered air force A-2s, after evaluating disc incidents, will determine the extent of investigation. Futile expenditure of military funds and manpower must be avoided. 2. "Flying discs" will be investigated as provided for in Counter Intelligence Incident Cases, taking cognizance of the USAF Operating Intelligence Echelon structure. Where it is evident that witnesses, who were together at the time of incident but who are widely separated at the time of investigation would corroborate each other's story, only one witness need be interrogated. If there is a reasonable indication that a reported incident is a hoax or the fabrication of a publicity seeking individual, no further investigative effort will be expended. However, a report of such circumstances will be submitted to the FBI office concerned. a. CIC personnel attached to the numbered air forces of this command may be utilized to prosecute the investigation of subject incidents. b. Investigations will be coordinated with the FBI Office concerned in accordance with instructions contained in letter, this headquarters, D 333.3 EX, subject, "Cooperation of FBI with AAF on Investigation of 'Flying Disc' Incidents," 3 September 1947. 3. Reports will be narrative in style and will cover only those facts pertinent to the subject. Where source credibility cannot be established, or when an incident lacks foundation, the report will merely state same. Two types of report will be submitted on all incidents. a. Spot Reports (fragmentary reports) will be submitted on all incidents and will be followed by a Letter Report. b. Letter Reports will be submitted to report the completed investigation of all "flying disc" incidents. 4. Reports will be submitted in duplicate promptly, usually by regular mail. However, Spot reports on incidents of substantial character, i.e., those in which the patent credibility of the witness is beyond challenge and whose technical

background compatible with his observations of an occurrence obviously not atmospheric phenomena, may be transmitted by TWX. Reports will be submitted directly to Headquarters, USAF, ATTN: Directorate of Intelligence, Air Intelligence Requirements Division. One informational copy of each report submitted will be forwarded to this command, ATTN: AC of S, Intelligence. Reports will be classified at least CONFIDENTIAL. BY COMMAND OF LIEUTENANT GENERAL STRATEMEYER: RICHARD W. GEUSS, Captain, USAF, Acting Asst Adj Gen.

Office Memorandum - United States Government. TO: Mr. Ladd. FROM: V. P. Keay. DATE: 3/1/48. SUBJECT: FLYING DISCS. SECURITY MATTER - X. Reference is made to a memorandum to you from Mr. J. P. Coyne in the above-captioned matter dated February 19, 1948. The memorandum indicated that the San Francisco Field Division had received a letter from the headquarters of the Air Defense Command, Mitchel Air Force Base, New York, dated February 4, 1948, entitled, "Investigation and Reporting of 'Flying Disc' Incidents." This communication indicated that investigations should be coordinated with the FBI. The Agent in Charge of the San Francisco Field Division inquired as to a change in policy regarding the investigation of flying discs. A letter was forwarded to San Francisco advising them that there had been no change in the Bureau's policy. This matter has been discussed by Special Agent S. W. Reynolds of the Liaison Section with Lieutenant Colonel C. P. Martin of the Intelligence Division of the Air Force. Colonel Martin advised Mr. Reynolds that apparently the Air Defense Command at Mitchel Field was not aware of the fact that the Bureau was no longer conducting investigations regarding flying discs. He stated that he would take the necessary action and straighten out the Air Defense Command as to the present policy regarding incidents of flying discs. SWR:md
