This declassified Air Intelligence Report No. 100-203-79 is a Top Secret study by the Directorate of Intelligence, Headquarters USAF, and the Office of Naval Intelligence, dated 10 December 1948. It looks at about 210 reported flying object incidents and concludes that some type of flying object has been observed, though what the objects are and where they come from cannot be determined. It considers domestic devices or Soviet aircraft based on German flying wing designs, and its appendices cover selected reports, explained cases and flying wing aircraft.
From the source: Release of 2026-07-10 Incident: 4/28/49, Virginia. This file contains a U.S. Air Force (USAF) Air Intelligence Division study, “Analysis of Flying Object Incidents in the United States,” Study No. 203, dated 04/28/1949. The analysis includes an assessment of various reported unidentified flying object (UFO) incidents and theories to account for their nature and origin. Overall, the study assesses that “it appears that some object has been seen; however, the identification of that object cannot be readily accomplished.” The study offers that two “reasonable” origins might account for the phenomena: technologies of a domestic or foreign origin. It also suggests that, if foreign, it is prudent for the United States to assume that UFO observations are attributable to scientific, military, or intelligence activities of the Soviet Union, and, in that case, to take seriously the threat such objects may pose. The file also contains selected contemporary UFO reports and examples of experimental “flying wing” type aircraft planforms that might account for certain commonly reported UFO characteristics. AARO Comment: This file appears to be a later revision of the file contained in DOW-UAP-D093, whose content is substantively similar.
APPENDIX "C" SELECTED REPORTS OF FLYING OBJECT INCIDENTS 1. A NUMBER of reports on unidentified flying objects come from observers who, because of their technical background and experience do not appear to be influenced by unfounded sensatlonallsm nor inclined to report explainable phenomena as new types of airborne devices. Some of the details of their reports are presented in this appendix, along with those from possibly less reliable sources who have reported evidence which 1s of. such a nature that it cannot be entirely ignored. 2. DESCRIPTIONS OF significant incidents, arranged chronologically, follow: a. During April 1947, two employees of the Weather Bureau Station at Richmond, Virginia re ported seeing a strange metallic disk on three occasions through the theodolite while making PIBAL observations. One observation was at 16,000 feet when a disk was followed for 15 seconds. The disk appeared metallic, shaped something like an ellipse with a flat bottom and a round top. It appeared below the balloon and was much larger in size. The disk appeared to be moving rather rapidly, aithough it was impossible to estimate its speed. The other observations were made at 27,000 feet in like manner. b. The following month, Byron B. Savage, a field engineer for Radio Corporation of America, reported a disk flying near his home in Oklahoma City, Oklahoma. The object was thought to be at an altitude between 10,000 feet and 18,000 feet, and was moving toward the north at a high rate of speed, leaving no trailing effects. c. While flylng at 10,000 feet on a course of 300 degrees, 30 miles northwest of Lake Meade, Nevada, an Air Force lieutenant rE:tported seeing flve or six white circular objects in close forma tion and traveling at an estimated speed of 286 miles per hour. This sighting occurred on 28 June 1947. d. The followl.ng day a party of three, two of them scientists, were motoring along Highway 17 toward the White Sand, New Mexico, V-2 firing grounds and reported seeing a large disk or sphere moving horizontally at a high speed and an estimated altitude of 10,000 feet. It was of uniform shape and had no protruding surfaces such as wings. The object was in sight for about 60 seconds before 1t disappeared to the northeast. The three observers agreed on the details of the sighting except that one thought he had seen vapor trails. e. On 7 July 1947, five Portland, Oregon police officers reported varying numbers of disks fly ing over differell.t parts of the city. All observations were made within a minute or two of 1305 hours. f. On the same day, William Rhoads of Phoenix, Arizona. allegedly saw a disk ci'rcling his locality during sunset and took two photographs. The resulting pictures (page 9) show a disk-like object with a round front and a square tail in plan torm. These photographs have been examined by experts who state they are true photographic images and do not appear to be imperfection ln the emulsion or imperfections 1n the lens.
