Mariana Great Falls Film (1950)

The "Mariana Great Falls Film" refers to a 16mm film purportedly shot by Nicholas Mariana, manager of the Great Falls, Montana, minor league baseball team. The film allegedly captured two unidentified bright objects flying over Great Falls on August 15, 1950. This event, alongside Mariana's account, became a notable case in early UFOlogy, scrutinized by the U.S. Air Force’s Project Blue Book.

• August 15, 1950, approximately 11:25 AM MST: Nicholas Mariana reportedly observed two bright objects in the sky over Great Falls, Montana.
• August 15, 1950: Mariana filmed the objects for approximately 16 seconds.
• August 16, 1950: Great Falls Tribune publishes an article detailing Mariana's sighting and film.
• August 1950: The film is reportedly shown privately to U.S. Air Force intelligence officers at the Pentagon. Later, it was analyzed by the Air Technical Intelligence Center (ATIC) at Wright-Patterson Air Force Base.
• September 1950: Civilian intelligence officer Captain Edward J. Ruppelt, future head of Project Blue Book, was briefed on the case.

• A 16mm film exists, taken by Nicholas Mariana, depicting two bright, disc-like objects in the sky.
• The incident occurred in Great Falls, Montana, on August 15, 1950.
• The U.S. Air Force, specifically the Air Technical Intelligence Center (ATIC) and later Project Blue Book, investigated the film and Mariana's claims.
• Official Air Force reports classified the incident as "unidentified" or "insufficient information" for a period.

• Nicholas Mariana claimed he observed two "flying saucers" performing synchronized maneuvers.
• Mariana reportedly described the objects as "silvery" and "flat on the bottom" with no visible wings, propellers, or exhaust.
• He stated the objects made no sound.
• Mariana reported that the objects appeared to revolve or rotate as they flew.
• He alleged that a third, darker object was visible for a brief moment in the background, though this was not consistently seen or analyzed.

• The primary witness was Nicholas Mariana. His account formed the basis of the incident.
• Mariana's secretary and daughter reportedly saw the objects after Mariana alerted them, though their observations were less detailed and did not involve the initial sighting or filming.

• The U.S. Air Force, through ATIC and Project Blue Book, conducted an official investigation.
• Project Blue Book Case File F-1950-7-15 is associated with this incident.
• Air Force photo analysts examined the 16mm film multiple times.
• Initial ATIC analysis in 1950 concluded the objects were likely F-94 jet fighters, despite Mariana's description.
• Later analysis by Project Blue Book personnel, including Captain Ruppelt, found the film evidence inconclusive. Ruppelt reportedly considered the case "unexplained" in his initial assessments.
• The Air Force eventually concluded the objects were two F-94 jet fighters, based on the assumption that Mariana had a limited field of view and misinterpreted what he saw, despite the lack of direct correlation or definitive proof from the film itself.

• Photo analysts from the U.S. Air Force examined the film for details such as shape, motion, and speed.
• The analysts were unable to definitively determine the objects' identity from the film alone due to factors like image quality, distance, and the lack of reference points.
• One key aspect of analysis focused on whether the "flash" seen on the objects in the film was consistent with sunlight reflecting off conventional aircraft or an unusual phenomenon.
• The lack of features, coupled with the objects' apparent rotation, led to an initial inability to identify them as conventional aircraft with certainty.

• The most common skeptical explanation, eventually adopted by the Air Force, is that the objects were U.S. Air Force F-94 jet fighters from the nearby Great Falls Air Force Base (now Malmstrom AFB).
• Skeptics suggest that Mariana, unfamiliar with military aircraft, misidentified the reflections of sunlight off the F-94s as a characteristic rotation or "flat bottom."
• The objects' movement and apparent size could be consistent with distant aircraft, especially if filmed through an amateur camera lens.

• The definitive identification of the objects in the Mariana film remains contested.
• The film itself does not offer sufficient detail to conclusively support either Mariana's "flying saucer" claim or the Air Force's F-94 explanation.
• The "rotation" Mariana described and the "flash" visible in the film have not been definitively reconciled with the F-94 hypothesis to the satisfaction of all observers.
• The initial hesitation and "unidentified" classification by Air Force intelligence officers suggest the F-94 explanation was not immediately obvious from the evidence.
