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.
