DOW-UAP-D098, Film Analysis of Unidentified Objects, 1953
This file contains a memorandum relating to the U.S. Naval Photographic Interpretation Center’s assessment of two films allegedly depicting unidentified airborne objects, captured in Montana and Utah in 1950 and 1952, respectively. The file documents the Center’s analytic process, assumptions that constrained its confidence level, tentative conclusions, and recommendations for future research. The Center assessed, generally, that the objects depicted in the film demonstrated characteristics that were inconsistent with those of natural phenomena or commonly known aerospace technologies. The memorandum documents the Center’s recommendation for a more well-resourced investigation to corroborate its presumptive findings, citing a lack of funding and personnel. The accompanying charts compare the film’s luminosity with the apparent angular size of the phenomena, using contemporary mathematical modeling and photogrammetric analysis techniques.
342: HS1-416511228 319.1 Flying Discs 1949
This file primarily contains incident reports on Unidentified Flying Objects (UFOs) written in compliance with the 1948 Flight Service Regulation (FSR) 200-4. The incidents were witnessed by military sources, as well as by some Civilian Aviation Authority (CAA) ones. The reports typically include information such as dates, locations, weather, and altitude, plus detailed descriptions of appearance and movement. Some messages from the Military Air Transport Service (MATS) and Army Airways Communications System (AACS) are also included, as well as additional military intelligence reports, several diagrams, and a report from a weather station in Japan.
CIA-UAP-005, German Scientist's Article on 'Flying Discs'
This 1950 CIA Information Report from Chile discusses a German scientist's article theorizing that "Flying Discs" could be explained as a new type of aircraft based on aerodynamic principles developed in German research facilities during and after WWI, using rotating cylinders or gas-turbines to create lift through boundary layer manipulation, rather than conventional wings. A redacted version of this report has been available on CIA's public website.
