U.S. Department of War · 1949-04-28 · 34 pages · text from the file's own layer

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.

ANALYSIS OF FLYING OB ECT INCIDENTS IN THE U. S.
SUMMARY AND CONCLUSIONS
PROBLEM
1. TO EXA:MlNE pattern of tactics of "Flying Saucers" (hereinafter referred to as flying objects)
and to develop conclusions as to the possibility of existence.
FACTS AND DISCUSSION
2. A DETAILED discussion of information bearing on the problem as set forth above 1s attached
as Appendix "A". The main points established therein are summarized below.
3. THE FREQUENCY of reported incidents, the similarity in many of the characteristics attributed
to the observed objects and the quality of observers considered as a whole, support the contention
that some type of flying object has been observed. Approximately 210 incidents have been reported.
• Among the observers reporting on such incidents are trained and experienced U.S. Weather Bureau
personnel, USAF rated officers, experienced civilian pilots, technicians associated with various re
search projects and technicians employed. by commercial airlines.
4. THE POSSIBILITY that reported observations of flying objects over the U.S. were influenced by
previous sightings of unidentified phenomena in Europe, particularly over Scandinavia 1n 1948, •and
that the observers reporting such incidents may have been interested in obtaining personal pubUcity
have been considered as possible explanations. However, these posslb111t1es seem to be improbable
when certain selected reports such as the one from U.S. Weather Bureau at Richmond are examined.
During observations of weather balloons at the Richmond Bureau, one well trained observer has
sighted strange metallic disks on three occasions and another observer has sighted a similar object
on one occasion. The last observation of un1denttf1ed objects was in Apr1i, 1947. On all four occa
sions the weather balloon and the unidentified objects were in view through the theodolite. These
observations at the Richmond Bureau occurred several months before publ1city on the flying saucers
appeared in a U.S. newspaper.
5. DESCRIPTIONS OF the flying objects fall lnto three configurat1on categories: (1) disk-shaped
(2) rough cigar-shaped {3) balls of fire. Varying conditions of visibility and differences in angles
at which the objects may have been viewed introduces a possibility that a single type object may
have been observed rather than three different types. This possibility is further substantiated by
the fact that 1n the areas where such objects have been observed the ratio of the three general
configurations is approximately the same.
6. THEREFORE, IT appears that some object has been seen; however, the identification of that
object cannot be readily; accomplished on the basis of information reported on each incident. It
ls possible that the object, or objects, may have been domestically launched devices such as weather
balloons, rockets, experimental flying wlng aircraft, or celestial phenomena. It is necessary to
obtain information on such domestic activity to confirm or deny this possibility. Depending upon
the degree with which this may be accomplished, foreign devices must then be considered as a
.. possibility.
7. THE PATTERN of sightings is definable. Sightings ~ave been most intense throughout the states
bordering the Atlantic and Pacific coast lines, and the central states of Ohio and Kentucky. A map
showing location of sightings is attached as Appendix "B"
