Project Blue Book Case File
St. Louis, MissouriJuly 1960
Summary
In July 1960, a resident of St. Louis, Missouri reported seeing an unusual object in the night sky over the course of two nights. The object appeared roughly the size of a quarter when held at arm's length, glowed bright red, and changed intensity as it moved.
On the first night, the witness observed the object for roughly 20 minutes. It hovered in place, moved backward once or twice, and eventually disappeared toward the east. On the second night, the same or similar object appeared again, this time for about 30 minutes before vanishing to the west. The witness noted that the object had sharply outlined edges and moved in ways that seemed deliberate rather than random.
The Air Force initially considered high-altitude aircraft (such as jets) as the most likely explanation. However, the file notes that if the witness's account of the object hovering in place is accepted as accurate, standard aircraft could be ruled out, leaving only helicopters as a conventional alternative. The investigators ultimately had insufficient data to reach a definitive conclusion and classified the case as unidentified.
