DOW-UAP-D098, Film Analysis of Unidentified Objects, 1953

Official Conclusion

Tentative: objects showed characteristics inconsistent with natural phenomena or commonly known aerospace technologies; further, better-resourced investigation recommended.

Official Description

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.
