I remember seeing this movie as a kid. I was very afraid. The speed of the objects passing behind a water tower in the foreground, show the objects were at a great distance. The Airforce determinedvthatvat 2.5 Mike's, the objects were traveling at 327.7 mph. Consider this was filmed by a military officer, lends credibility to it.
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.
