The Mariana Film

On August 15, 1950 (the date carries minor dispute), Nick Mariana, general manager of the Great Falls Electrics baseball team, filmed two bright objects crossing the sky above the ballpark with his 16mm camera, after seeing them stop and hover by his account. The 16 seconds of footage became the first widely analyzed UFO film in history.

Mariana and his secretary, Virginia Raunig, saw the objects from the grandstand; he retrieved his camera from his car and filmed as two bright, apparently disc-like points moved steadily across the sky behind a water tower. Mariana reported the objects as rotating silvery discs; he also later claimed the film's first frames, showing larger, clearly disc-shaped objects, were removed while in Air Force custody, which the Air Force denied.

The surviving film, witness testimony from two people, and records showing two F-94 jets landed at the nearby base minutes before or around the filming, the fact on which everything turns.

The Air Force's analysis concluded the objects were probably the two jets reflecting sunlight. The case was reviewed for the Robertson Panel (1953), which screened the film, and re-analyzed by the Condon Committee (1969), whose photographic study found the jet explanation strained by the objects' appearance and motion but could not exclude it, leaving the case unexplained in its text.

Skeptics hold the jets fit: timing, direction, and sun-glint can turn aircraft into featureless bright ellipses on 1950 film stock. Proponents cite Mariana's account of hovering before filming, the Condon analysts' own difficulties (the objects' constant brightness and spacing), and the missing-frames claim. Robert Baker's 1950s-era engineering analysis for Douglas Aircraft also found the airplane hypothesis difficult. The film remains what it was: 16 ambiguous seconds carrying 75 years of argument.
