IncidentMariana Film (15 August 1950)

On the morning of 15 August 1950 at approximately 11:30 local time, Nicholas Mariana, the general manager of the Great Falls Selectrics — a minor-league baseball team in the Pioneer League based at Legion Park in Great Falls, Montana — was at the empty stadium with his secretary Virginia Raunig when he observed two silvery, disc-shaped objects flying over the park from the southeast. Mariana retrieved his 16mm Revere movie camera from his car and exposed approximately 16 seconds of Kodachrome color film of the objects as they passed overhead. The objects were also observed by Raunig, who later provided a confirming signed statement.

Mariana developed the film and showed it locally; a copy was provided to the U.S. Air Force in October 1950. The Air Force’s Air Materiel Command at Wright Field analyzed the footage and concluded the objects were two F-94 jet interceptors returning to Malmstrom Air Force Base. Mariana disputed the F-94 attribution: the time-of-day, the absence of visible contrails, and the disc-shaped morphology in the footage were inconsistent with F-94s. He also stated, in subsequent interviews, that the Air Force had returned the film to him with several feet of the original footage missing — a claim that became central to the case’s continuing literature.

The film was reanalyzed by the U.S. Navy’s Naval Photographic Interpretation Center (NPIC) in 1954, and by the Robertson Panel review of 1953 in passing. Project Blue Book’s final classification of the case was “unknown” — one of the 701 cases that remained “unidentified” at program closure in 1969. The Condon Committee reviewed the case in 1968 and largely accepted the F-94 explanation, though the committee’s investigator (William K. Hartmann, planetary scientist) noted that the apparent angular size and motion of the objects in the film were difficult to reconcile with the F-94 hypothesis.

The Mariana film remains in circulation in copies derived from the original 16mm reel; the Mariana family donated the original to the Smithsonian National Air and Space Museum in 1999. The film is one of the earliest motion-picture UAP records and one of the few subjected to formal analysis by both the USAF and the U.S. Navy.
