FBI-UAP-D014, Correspondence Relating to UFO Sightings, 1967, 1974
This file contains two pieces of correspondence. The first, dated 9/22/1967, relays a description of an incident provided by an eleven-year-old child in which they heard a “weird” noise and saw a “flash of light.” The second, dated 9/30/1974 and 10/10/1974, is an exchange of letters between the Federal Bureau of Investigation (FBI) and Mr. Larry Bryant regarding an “alleged April 8, 1954 sighting of an occupied unidentified flying object (UFO).” The FBI’s response to Mr. Bryant’s inquiry indicated that it maintained no record of such an event, and that, circa 1974, the Bureau does not collect information regarding UFO sightings.

DOW-UAP-D095, Joint U.S.-Canadian Aviation Projects and UFO Sighting Reports, 1954-1955
This file contains reports, memoranda, and correspondence concerning various then-developmental vertical take-off and landing (VTOL) aircraft. The file includes assessments of the experimental potential of the “Avro Project Y2,” a joint U.S.-Canadian near-circular VTOL aircraft that is similar in appearance to contemporary popular descriptions of unidentified flying objects (UFO). A 1954 memorandum opines that VTOL aircraft with a circular planform may be mistaken for UFOs to observers unfamiliar with such technologies. It also recommends that UFO reports in the vicinity of Soviet military operations or assets be re-examined to assess whether they may be attributable to previously unknown advanced VTOL aircraft of foreign design. The file also contains correspondence relating to a UFO incident involving a U.S. Air Force (USAF) KC-97 flying near Newfoundland, Canada in July 1955. A USAF committee found that the characteristics described in the report were inconsistent with those of known Soviet, American, or Canadian military systems. The committee was also “unable to explain the simultaneous ground radar returns and aircrew visual sightings.” It also contains correspondence relating to the potential value of data from incidental radar collection of meteors entering the atmosphere. USAF Air Research and Development Command recommended using that data to improve the performance of the AN/FPS-17 radar system. Finally, the file contains correspondence indicating support for the Communications Instructions for Reporting Vital Intelligence Sightings (CIRVIS) program, a joint U.S.-Canadian civil-military program to standardize reporting methods for unusual or unidentified airborne and maritime hazards and threats.

DOW-UAP-D094, Analysis of Flying Object Incidents in the United States, 1949
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.

DOW-UAP-D092, Department of the Air Force Committee to Review Project Bluebook, 1966-1967
This file documents the 1966-1967 deliberations and recommendations of the U.S. Air Force (USAF) Scientific Advisory Board’s Ad Hoc Committee to Review Project Blue Book. Project Blue Book was a 1952-1969 USAF program to investigate the nature and origin of unidentified flying objects (UFO). The Committee recommended that the USAF contract a scientific team composed of university-affiliated representatives to investigate selected UFO sightings. The USAF subsequently adopted the Committee’s recommendation.

DOW-UAP-D091, Range Fouler Debrief, Atlantic Ocean, 2020
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.

DOW-UAP-D090, Range Fouler Debrief, Eastern United States, 2019
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-PR112.” Five U.S. military-affiliated personnel reported observing an object “with flight characteristics unlike anything [the observer] had seen in 28 years [of service] for the U.S. Air Force and U.S. Navy. The report characterizes the phenomenon as “small” and “travelling in a straight line opposite [the platform’s] direction at high speed.” The reporter added that, “others with equal or more experience were also unsure as to what the object might be.” 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.

DOE-UAP-D004, Los Alamos Conference on Aerial Phenomena, 1949
This document is a transcript of a 1949 conference held at Los Alamos Scientific Laboratory (now Los Alamos National Laboratory), Los Alamos, New Mexico. Attendees included several eminent scientists and physicists, many of whom had contributed to the development of the first nuclear weapons during the Manhattan Project. The purpose of the conference was to discuss and gather hypotheses to account for the nature and origin of a phenomenon involving “green fireballs” that had been reported over a period of several months in the vicinity of the laboratory. The group did not come to a consensus on a likely attribution for the phenomenon, though a leading hypothesis was that the observations may have been related to meteors entering the atmosphere at a shallow angle and high altitude. Dr. Edward Teller suggested that if not a “material body,” an “electron phenomenon” might be the cause, while Dr. Lincoln LaPaz, an expert specializing in meteorics, expressed that “nothing like this, to [his] knowledge, has ever been observed in the case of meteorite drops.”

CIA-UAP-D021, Analysis of Unconventional Aircraft Sightings, 1955
Sections 1 and 2 of this memorandum document a 1955 analysis of reports of “flying saucers” or “unconventional aircraft,” referencing the incident described in observer debriefings contained within CIA-UAP-D020. The memo summarizes the incident as consisting of two lights rising vertically, then passing above the observers. The memo contains caveating language that suggests the author concluded that the reports, as described, did not indicate the presence of an “unconventional aircraft.” Section 3 cites a previous finding by Dr. [Howard] Robertson (of the 1953 Robertson Panel) that “almost all the sightings […] represented no threat to the U.S.” Section 4 discusses the state of then-current research into “saucer-like aircraft” under Project “Y,” a contemporary joint U.S.-Canadian aerospace development program.

CIA-UAP-D020, Memorandum on Unconventional Aircraft Sightings, 1955
This memorandum summarizes a Central Intelligence Agency (CIA) debriefing of a group of four individuals who reported observing a “flying saucer” or “unconventional aircraft” in 1955. The group, which included U.S. Senator Richard Russell, a U.S. military service member, and two U.S. Government officials, reported observing a luminescent “greenish-yellow” phenomenon, as seen from aboard a train while traveling within the Soviet Union, in present-day Azerbaijan, between Baku and Tiflis (Tbilisi, Georgia). The document concludes by stating that the observation can “probably be explained as steep climbing aircraft or missiles,” and that “the evidence does not appear sufficiently firm to warrant the conclusion that the Soviets have developed […] a radically new type of aircraft.” The document “CIA-UAP-D021” contains a contemporary analysis of the incident.
