The Tremonton, Utah UFO Color Film
July 2, 1952
NICAP Synopsis

One frame from the Utah film showing maneuvering discs.

NICAP UFO Evidence::
Warrant Officer D.C. Newhouse,  USN, obtained 16 mm color movies of a group of UFOs which he and his wife observed visually near Tremonton, Utah. At relatively close range, UFOs appeared flat and circular "shaped like two saucers, one inverted on top of the other." Mr. Newhouse unpacked his Bell and Howell Automaster camera, with 3-inch telephoto lens, from the trunk of his car and obtained about 1200 frames of the UFOs on Daylight Kodachrome film. During the filming, Mr. Newhouse changed the iris stop of the camera from f/8 to f/16. The film was submitted to Navy authorities, who forwarded it to the Air Force at ATIC in Dayton, Ohio, where it was studied for several months. According to Mr. Newhouse, frames of the movie showing a single UFO moving away over the horizon (hence providing some ranging information) were missing when the film was returned. The hypothesis that the objects were out of focus sea gulls was considered by the Air Force, but could neither be confirmed nor denied. The report of Photogrammetric analysis by Dr. Robert M.L. Baker, Jr., Douglas Aircraft Corporation (which included a study of the 1950 Montana film) also examined this possibility. He states: "The motion of the objects is not exactly what one would expect from a flock of soaring birds (not the slightest indication of a decrease in brightness due to periodic turning with the wind or flapping)." Dr. Baker reports that no definite conclusion could be reached, but "the evidence remains rather contradictory and no single hypothesis of a natural phenomenon yet suggested seems to completely account for the UFO involved."
