This 1949 War Department file 319.1, Flying Discs, is a set of U.S. Air Force Flight Service Center reports on unidentified flying objects sent to the Air Materiel Command at Wright-Patterson. The reports cover sightings over Kansas City and Olathe, Rome, Seattle, Greenville, Spokane, Medford, Columbus, Portland, Mountain Home, Jackson and Chanute AFB. Most remain unexplained, but the Greenville object was found to be a weather balloon. The file also holds a 1948 order telling units to report disc sightings.

TO : MATS A-2, ATTN: Capt. Hathaway DATE: 8 february 1949 FROM AACS A-2 AACS/A-2/CCR/mlb/2113 COMMENT NO.1 SUBJECT: Sighting of "Flying Discs" A strong possibility exists that the "flying disc" might have been a piece of cardboard, or light metallic substance carried aloft by the funneled air currents over Hickam. The nearby cane fields give off a considerable amount of moisture, thereby creating a "dead space." The prevailing winds striking this area are directed upward over the field, and hence could carry inanimate objects up with them. Then, too, the altitude given could be considerably off, inasmuch as the object sighted was thin. Judging heights of such objects is difficult enough, even if the object were 3-4 feet in thickness. Suggest you check records of Air Weather Service for confirmation of wind peculiarities over Hickam. 2 Incls 1. Cy ltr, 1810th AACS Gp, 8 Jan 49, w/2 ind 2.
