Summary
# A Milestone Week for UFO Reports
In July 1952, the U.S. Air Force received a surge of UFO sightings across multiple states. One particular report from Columbia, Missouri, stood out to investigators because of who made it and how carefully he documented what he saw.
The witness was a professional weather observer who held a civilian pilot's license and had logged 1,800 hours flying C-47 cargo planes during World War II. On the night of July 1, 1952, starting around 1:40 a.m. (0140 CST), he noticed a bright star-like object in the sky to the north-northeast of Columbia. An aurora borealis (a natural light display in the upper atmosphere) was visible that night, which made the object stand out sharply against the dark background below the colorful lights.
The observer watched for several minutes and realized the object was moving differently from the stars around it. He retrieved a theodolite (a surveying instrument that measures angles and distances precisely) and followed the object through it for more than two hours until daylight made it impossible to see. Through the theodolite, the object changed color irregularly, shifting from red to green. By naked eye, it flickered and twinkled like a star. The observer recorded precise angle measurements and times throughout the sighting, documenting the object's slow drift across the sky. Between 3:10 a.m. and 3:35 a.m., the object lost its color but continued to look like Jupiter as viewed through the theodolite. The observer noted it appeared to be extremely distant and moving away from Earth.
Two other witnesses confirmed the sighting. One was a communications official with the Civil Aeronautics Administration (CAA), the other a weather observer who arrived on duty before sunrise. In his formal statement, the primary observer noted this was the fifth unidentified flying object he had seen since June 1950, though he had never reported the earlier sightings. He called this one the least dramatic of them all.
The Air Force found no conventional explanation for the sighting and took no interception action. The file is labeled unidentified, the official evaluation by the U.S. Air Force. The full case file as held by the National Archives spans 34 pages.
