HEADQUARTERS ARMY AIR FORCES ROUTING AND RECORD SHEET SUBJECT: Flying Saucer Phenomena TO: Deputy Chief of Air Staff for Research & Development DATE 22 August 1947 COMMENT N FROM: AC/AS-2, Air Intelligence Requirements Division It Col Garrett selon Collection Branch 1. From a detailed study of certain reported observations on the flying saucers, selected for their veracity and reliability, it is apparent that several aspects of their appearance have a common pattern. 2. Before pursuing its investigation of these objects any further, this Office requests assurance that no research project of the Army Air Forces, at present being t-flown, has the following characteristics and that it may therefore be assumed me recent flying saucer "mystery" is not of United States origin: a. Surface is metallic - indicating a metallic skin, at least. b. When a trail is observed, it is a lightly colored blue-brown haze, similar to a rocket engine's exhaust. Contrary to a rocket of the solid type, one observation indicates that the fuel may be throttled, which would indicate a liquid rocket engine. ce As to shape, all observations state that the object is circular, or at least elliptical, flat on the bottom and slightly domed on the top. d. Size estimates place it somewhere near the size of a C-54 or Constellation as they would appear while flying at 10,000', e. Some reports describe two tabs located at the rear and symmetrical about axis of flight motion. j f. Flights have been reported containing from three to nine objects, flying good formation on each other, with speeds always above 300 knots. ge The discs oscillate laterally while flying along, which could be snaking.
