This Top Secret Air Intelligence Division Study No. 203, prepared jointly by USAF and ONI intelligence and dated 10 December 1948, analyzes about 210 reported flying object incidents in the United States. It concludes that some type of flying object has been observed, but that its identification and origin cannot be determined. The study weighs domestic explanations such as weather balloons, rockets, flying wing aircraft and celestial phenomena against possible Soviet devices based on German flying wing designs. Its appendices include selected incident reports and descriptions of flying wing aircraft.
From the source: Release of 2026-07-10 Incident: 12/10/48, 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 12/10/1948. 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 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 an earlier draft version of the file contained in DOW-UAP-D094, whose content is substantively similar.

## TOP GEORET First of all, the scientific objectives of the U.S.S.R. have been stated many times and indicated in many forms. The most clear-cut statement of this objective is probably the one contained in the preamble to the Fourth Five-year Plan (1946-1950) which states that the objective of Soviet science is to overtake and surpass the scientific and technical developments of the capitalist nations. It apparently would be an impossible task for the Soviet Union to accomplish such an objective by proceeding step-by-step along the same lines of development already achieved in the capitalist nations. This would mean that it would be necessary to rapidly proceed through each phase of aeronautical development that has already been accomplished in this country, and this probably would never have any prospects of accelerating Soviet development beyond any point reached by the U.S. The obvious answer to accomplish their objective of not only overtaking, but surpassing the capitalist countries would be a scientific shortcut. This possibility is not so remote when examined on the basis of our knowledge of the current situation in the U.S.S.R. Provided Soviet emphasis was given to the most promising and advanced ideas acquired from Germany in 1945 and the work aided by German scientists, the possibility of catching up and possibly surpassing other nations in technical developments becomes more realistic. It becomes even more realistic if the Soviets have shown a tendency to concentrate on certain developments which have still not received a maximum of priority in our own programs. It is known that the U.S.S.R. has since 1945 enlisted the services of Dr. Guenther Bock, a German who headed all development of low aspect ratio (flying wing) type aircraft in Germany. Dr. Bock is believed to be the top German scientist in charge at TSAGI and TSIAM which are "Air Materiel Command" type organizations in the U.S.S.R. Further, it is believed that Dr. Bock has made available all German plans for flying wing type aircraft to the Soviets. Among the designs considered by TOP SECRET
