CIA-UAP-006, Sighting Of Unconventional Aircraft
This CIA information report from November 1955 describes a US national's eyewitness account of triangular aircraft with wing lights launch at a steep angle from an airfield near Baku, Azerbaijan on October 4, 1955. A redacted version of this report has been available on CIA's public website.
CIA-UAP-018, Report of Unusual Flying Object Sightings and Attendant Scientific Activity
A 1955 report on a UFO sighting in Hungary. The information came from a letter between Hungarian relatives, living in the USA and Budapest. A more redacted version of the report has been available on CIA's public website.
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.
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.
전쟁부(DOW)-미확인 이상 현상(UAP)-D095, 미국-캐나다 합동 항공 프로젝트 및 UFO 목격 보고서, 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-D096, Correspondence Relating to Project Blue Book, 1955
This file contains correspondence relating to Project Blue Book, a 1952-1969 U.S. Air Force program to investigate the nature and origin of unidentified flying objects (UFO). The correspondence includes letters and memoranda sent between various departments and agencies of the U.S. Government, the Legislative Branch, and private citizens concerning UFO sightings and the research and findings of Project Blue Book.
