PENTAGON UFO FILE · DOCUMENT · DOW-UAP-D094Analysis of Flying Object Incidents in the United States, 1949
This is the finished, typeset form of Air Intelligence Division Study No. 203, issued as Air Intelligence Report No. 100-203-79 under the joint names of the Air Force Directorate of Intelligence and the Office of Naval Intelligence. The release dates this copy to April 1949, but the report inside still carries its 10 December 1948 study date, and it arrived with a document-control cover sheet and an Espionage Act warning. Its typed draft is DOW-UAP-D093.
The “possible tactics” section
The printed report is easiest to read for its Appendix A, which openly says it is provisional. Assuming for argument’s sake that the objects were Soviet, it offered four motives: undermining U.S. confidence in the atom bomb, photographic reconnaissance, testing air defenses, and getting to know U.S. terrain. It linked the American reports to the unexplained objects seen over Scandinavia in 1946 and noted sightings near Oak Ridge, Las Cruces and the Hanford Works — sites, it said, that Soviet collectors could not reach. (It places Hanford in Oregon; the site is in Washington State.)
The authors also observed that the American public mostly dismissed the reports as the work of “crack pots,” misidentified ordinary objects, or a secret U.S. project.
What the appendices hold
Besides the analysis, the report includes a map of sightings as of 1 August 1948, a set of selected incident reports and a survey of flying-wing aircraft from Germany, Britain and the United States. Its own conclusion was that it could not say whether the sightings were misidentified domestic devices, natural phenomena or foreign aircraft.
The official description
From war.gov/UFO, released July 10, 2026, quoted in full
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.
