THE GREAT FALLS AND TREMONTON FILMS

GREAT FALLS, MONTANA, AUGUST 15, 1950

Nick Mariana, general manager of the Great Falls Electrics baseball team, was at the ballpark with his secretary Virginia Raunig on the morning of August 15, 1950 when both saw two bright, silvery objects moving over the city. Mariana ran for his 16mm movie camera and captured roughly sixteen seconds of color footage. It is the earliest UFO film the Air Force ever formally investigated.

Analysts at Wright-Patterson Air Force Base concluded the objects were reflections from two F-94 jet fighters known to have been in the area. Mariana disputed the handling of the film itself, claiming the opening frames, the ones he said showed rotating disc shapes most clearly, were removed while the reel was in government custody. The Air Force acknowledged removing only a single damaged frame. That dispute has never been resolved from the record, and both accounts still stand as claims rather than findings.

The case did not stay closed. In 1956 Robert M. L. Baker Jr., then at Douglas Aircraft, studied the footage in detail and judged the jet reflection explanation "quite strained." When the Air Force funded Condon Committee reviewed it in the late 1960s, its own members split: William Hartmann concluded that aircraft could not be entirely ruled out but that the explanation strained credibility.

TREMONTON, UTAH, JULY 2, 1952

Delbert Newhouse was a U.S. Navy chief warrant officer and a chief photographer with more than twenty years of service. On July 2, 1952, driving near Tremonton, Utah with his family, he stopped and filmed a group of bright objects moving against a clear sky. His professional background is the reason the film carried weight: the government was not evaluating footage from an anonymous bystander.

The film went to the U.S. Navy's photographic interpretation laboratory, which spent an estimated thousand man hours on it. Its conclusion was unusually direct for a technical unit: the objects were not birds, not balloons and not aircraft, and were not reflections, because the lab observed no blinking as the objects passed through sixty degrees of arc. What remained, in the lab's assessment, was that the objects were self-luminous.

THE ROBERTSON PANEL DISAGREED

In January 1953 the CIA convened a panel of scientists to review the government's UFO evidence, chaired by physicist Howard P. Robertson and including Luis Alvarez, Samuel Goudsmit, Thornton Page and Lloyd Berkner, with Frederick Durant as secretary and J. Allen Hynek attending as a consultant. It met from January 14 to 18, and the Great Falls and Tremonton films were the two centerpiece exhibits.

The panel set aside the Navy laboratory's finding. For Tremonton it proposed birds, specifically seagulls, a view it adopted after being shown a short film demonstrating how brightly gulls reflect sunlight. For Great Falls it concluded the objects were probably aircraft and the bright lights their reflections, restoring the original Wright-Patterson explanation. Its unanimous overall finding was that there was no evidence of a direct threat to national security. Newhouse, the career Navy photographer who shot the Utah footage, rejected the bird explanation for the rest of his life, maintaining that the objects had looked structured and metallic when he first saw them at closer range.

WHAT PURSUE RELEASE 05 ADDS

Until now the Navy laboratory's position was known mainly through secondhand summaries of the Robertson Panel proceedings. Release 05, published August 7, 2026, includes DOW-UAP-D098, "Film Analysis of Unidentified Objects, 1953," a 23 page Department of War file that is the memorandum itself.

By the government's own description, the file covers the U.S. Naval Photographic Interpretation Center's assessment of two films of unidentified airborne objects captured in Montana and Utah in 1950 and 1952. It documents the Center's analytic process, the assumptions that constrained its confidence level, its tentative conclusions and its recommendations for future research. The Center assessed, generally, that the objects showed characteristics inconsistent with natural phenomena or commonly known aerospace technologies. It recommended a better resourced investigation to corroborate what it called presumptive findings, citing a shortage of funding and personnel. Accompanying charts compare the films' luminosity against the apparent angular size of the objects, using the mathematical modeling and photogrammetric techniques available at the time.

WHAT IS DOCUMENTED, AND WHAT IS NOT

The memorandum documents a disagreement inside the government in 1953, between a technical unit that had spent months on the footage and a review panel that reached a different conclusion in five days. That disagreement is now a matter of public record rather than inference.

It is not a finding of non-human origin, and the file does not claim to be one. "Inconsistent with commonly known aerospace technologies" is a statement about what a 1953 laboratory could match the footage against, bounded by the Center's own stated assumptions and its own description of its conclusions as tentative and presumptive. The Center asked for a larger study to test them. On the record as it stands, that study was never funded.
