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.

## c. Gotha P 60 A
This was the first of the P 60 series of jet fighters. It is a flying wing type and, since the pilot and observer lie prone, there is no projecting canopy, thus permitting a particularly clean design. The jet units are mounted at the rear of the center section, one above and one below.
Span 40 feet 8 $ \frac{1}{2} $ in.
Wing Area 504 square feet
Power Plant 2 BMW 003 turbo jet units
Max. Speed (23,000 feet) 596 miles per hour
## d. Heinkel P 1080
This is a single-seat fighter with a sharply swept-back wing, resembling a flying wing type, but having a single fin and rudder with no tail plane.
Span 29.2 feet Wing area 218 square feet No performance estimates are available.
## e. Junkers HF 130
Of the flying wing type, this project was established
## as a long-range, high-speed jet bomber.

Wing Area 1290 square feet
Power Plant 4 HeS 011 turbo jet
Max. Speed 620 miles per hour
Range 3700 miles
## f. Me 329
This is a tailless mid-wing monoplane driven by two
pusher propellers with the engines centrally located in the wings on each side of the stubby rounded fuselage.

## g. Horten Wing
The closest resemblance to the estimated configuration of "Flying Disks" is represented by the Horten Wing aircraft. Work on Report, from the pursue collection.
