Great Falls 1950 — the Nick Mariana film and one of the earliest UAP cine-records
On August 15, 1950, Nicholas Mariana, the general manager of the Great Falls Selectrics minor-league baseball team in Great Falls, Montana, filmed approximately sixteen seconds of 16mm colour footage showing two bright objects moving across the sky above the team's empty stadium. The Mariana film is, with the Newhouse film of 1952, one of the two earliest UAP cine-records to enter the formal Project Blue Book documentary archive and is among the most-analysed UAP films of the mid-twentieth century.
What the film shows
The film captures two bright luminous points moving across the sky in tandem at a steady relative velocity. The objects appear as bright discs rather than as distinct structural shapes, and they pass behind a water tower in the foreground at one point in the sequence — providing a parallax reference that subsequent analysts have used to attempt to reconstruct their actual distance and altitude. Mariana's contemporaneous account stated that the objects were visually distinct as silvery rotating discs at the time of observation, and that the film records only the brighter luminous signature of the objects rather than their full visual appearance.
The Air Force analysis and its disputed history
Mariana submitted the film to the Air Force shortly after the incident. According to his subsequent statements, the film was returned to him after analysis with portions of the original footage missing — specifically, the segments which he asserted showed the objects' rotating disc shape most clearly. The Air Force has denied removing any footage. This dispute over the integrity of the returned film is one of the most-cited grievances against Project Blue Book in the historical UAP literature and has continued to be debated in subsequent decades.
The Air Force's official conventional explanation for the case was that the objects were reflections from two US Air Force F-94 jets known to have been in the area on training flights. This explanation rests on the timing of the F-94 flights and was the position taken by Project Blue Book in closing the case. Subsequent independent reviewers, including by Dr Robert M.L. Baker Jr., examined the film and concluded that the objects' apparent motion and geometry were not consistent with the jet-reflection hypothesis as advanced. The Condon Committee's 1968 report also examined the case and noted methodological difficulties with both the Air Force explanation and with any alternative.
The case's enduring status
The Mariana film remains one of the small set of historical UAP films which has continued to attract serious analytical attention from researchers across the spectrum of opinion. It is also one of the foundational cases in the public narrative of Project Blue Book itself, both because of the disputed handling of the original film and because of the involvement of a credible non-aviation civilian witness in a public-facing professional role.
