Mariana UFO Film

On August 15, 1950, Nick Mariana — the general manager of the Great Falls Electrics minor league baseball team in Great Falls, Montana — filmed two disc-shaped, rotating objects on 16mm Kodachrome color film as they moved across the sky over Skylite Stadium. The footage, approximately 16 seconds of which survived after portions were removed by the U.S. Air Force following their investigation, remains one of the most analyzed pieces of UAP film evidence from the early Cold War era and the earliest color film footage of UAP generally regarded as genuine by scientific analysts.

Mariana was testing his movie camera at the stadium when he noticed two bright objects in the northwest. He began filming immediately and captured the objects as they moved in a steady, parallel trajectory. The objects had a clearly disc-like appearance with a bright reflection point on each, and appeared to rotate or spin as they flew. Mariana's secretary, Virginia Raunig, was present and also observed the objects, providing corroboration for the initial sighting.

The U.S. Air Force requested Mariana's film for analysis as part of Project Grudge and subsequently Project Blue Book. When the film was returned to Mariana, he reported that a portion showing the objects at closer range — in which more detail was visible — had been removed. The Air Force's subsequent classification of the case as explainable by reflections from F-94 jet fighters was disputed by Mariana, who maintained the objects had been present before any jets arrived in the area, and by subsequent independent analysts.

Dr. Robert Baker, an astronomer and aerospace engineer, analyzed the film and concluded that the objects were not conventional aircraft, birds, balloons, or optical artifacts. His analysis was submitted to the American Astronomical Society. Optical physicist Dr. Bruce Maccabee later conducted an extensive technical analysis and concluded the objects were genuine, anomalous aerial objects producing their own light or reflecting sunlight in a manner inconsistent with the jet reflection hypothesis.

The Mariana film is considered one of a small number of early-era UAP films with sufficient technical quality to have survived rigorous scientific scrutiny, and its removal and partial return by the Air Force remains one of the documented cases in which official handling of UAP evidence has been questioned by witnesses and independent researchers.
