Project Blue Book Mariana UFO Incident PDF

NARA via The Black Vault · 114 pages · text by OCR

This Project Blue Book file, released through The Black Vault, collects US Air Force records from 1950 to 1959 on the movie film Nicholas Mariana shot at Great Falls, Montana on 15 August 1950. It includes the OSI interview report, letters about borrowing and copying the film, and a 1956 Douglas Aircraft analysis. Blue Book's own findings were not consistent: one letter lists the cause as unknown, while later memos conclude the objects were probably two F-94 jets.

Montana Case: In 1950, after an ATIC interrogation of witnesses and evaluation of data, and our opinion at that was that the UFO's apparently were two F-94 aircraft. In support of this contention, a few weeks ago an extremely able and very detailed analysis was made by a private laboratory of the film strip in question. Their conclusions, in part, were that," photographs of the UFO's indicate that airplane reflections might possibly look like the images shown on the film. The fact that the images do fade is reminiscent of airplane reflective phenomena". Also, strong corroborative evidence is given by simulated photographs of aircraft at various distances made by this laboratory which show that aircraft can look similar to the two white blops shown on the Montana films. There is, therefore, no compelling reason to alter our original evaluation
