🇺🇸 USAF — Project Blue Book
In January 1958, a witness in University City, Missouri, observed an aerial object that appeared the size of a silver dollar. The object had blue and white colors and was moving rapidly downward. The witness heard no sound and could not determine if it had a tail. Although no photos were taken, the possibility of a meteor was considered. The report concluded it was likely an astronomical phenomenon, but other explanations were not ruled out.
The testimony was recorded as a ground visual observation, with no radar or image data. The observer described the object as round and luminous, and saw it disappear behind a building. Although the exact observation time was not specified, the available data suggest it was a brief event. This case is part of the Project 10073 files, where unexplained sighting reports are collected.
