In 1952, at the request of the Pentagon, I reopened the investigation of the Montana Movie. Working through an intelligence officer at the Great Falls AFB, I had Mariana reinterrogated and obtained a copy of his movie, which I sent to the photo lab. When the photo lab got the movie, they had a little something to work with because the two UFO's had passed behind a reference point, the water tower. Their calculations quickly confirmed that the objects were not birds, balloons, or meteors. Balloons drift with the wind and the wind was not blowing in the direction that the two UFO's were traveling. No exact speeds could be measured, but the lab could determine that the lights were traveling too fast to be birds and too slow to be meteors. This left airplanes as the only answer. The intelligence officer at Great Falls had dug through huge stacks of files and found that only two airplanes, two F-94's, were near the city during the sighting and that they had landed about two minutes afterwards. Both Mariana and his secretary, who had also seen the UFO's, had said that the two jets had appeared in another part of the sky only a minute or two after the two UFO's had disappeared in the southeast. This in itself would eliminate the jets as candidates for the UFO's, but we wanted to double-check. The two circular lights didn't look like F-94's, but anyone who has done any flying can tell you that an airplane so far away that it can't be seen can suddenly catch the sun's rays and make a brilliant flash. First we studied the flight paths of the two F-94's. We knew the landing pattern that was being used on the day of the sighting, and we knew when the two F-94's landed. The two jets just weren't anywhere close to where the two UFO's had been. Next we studied each individual light and both appeared to be too steady to be reflections. We drew a blank on the Montana Movie--it was an unknown. We also drew a blank on the Tremonton Movie, a movie that had been taken by a Navy Chief Photographer, Warrant Officer Delbert C. Newhouse, on July 2, 1952. Our report on the incident showed that Newhouse, his wife, and their two children were driving to Oakland, California, from the east coast on this eventful day. They had just passed through Tremonton, Utah, a town north of Salt Lake City, and had traveled about 7 miles on U.S. Highway 30S when Mrs. Newhouse noticed a group of objects in the sky. She pointed them out to her husband; he looked, pulled over to the side of the road, stopped the car, and jumped out to get a better look. He didn't have to look very long to realize that something highly unusual was taking place because in his twenty-one years in the Navy and 2,000 hours' flying time as an aerial photographer, he'd never seen anything like this. About a dozen shiny disklike objects were "milling around the sky in a rough formation."
