Analysis of Flying Object Incidents in the United States, 1949
🏛️ Department of War
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.

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.

Project Sign Progress Report, 1948
Department of War
This file contains an initial report from the Air Materiel Command regarding Project Sign. Project Sign was a 1948-1949 U.S. Air Force program to investigate the nature and origin of unidentified flying objects (UFO). The report details 100 UFO sightings from 1947-1948. The file also contains an article excerpted from “The Aeroplane,” an aviation-focused periodical magazine published between 1911 and 1968, titled “The Biology of the Flying Saucer.”
Range Fouler Debrief, Atlantic Ocean, 2020
Department of War
This document is a Range Fouler Debrief, a standardized reporting form the U.S. Navy uses to record the circumstances surrounding an unauthorized intrusion into controlled airspace during active military operations or training. These reports contain a narrative description of the observer’s experiences. This report accompanies the video titled “DOW-UAP-PR116.” A U.S. military operator reported observing an object, describing the phenomenon as “darker, maroonish color, approximately 12-15 feet in height.” The report describes the phenomenon “travel[ing] with the wind” and noted that it did not “maneuver or change direction.” It also describes the phenomenon as appearing as a “large, somewhat deformed balloon.” All descriptive and estimative language contained in this report reflects the reporter’s subjective interpretation at the time of the event. Such characterizations should not be interpreted as a conclusive indication of the presence or absence of any intrinsic object features or performance characteristics.
