UFO sighted near Reims in 1960

Summary

A pilot of a C-47 reported an object shaped like a spool of thread, about 12 feet tall, with a white central body and red and blue-green discs at the ends. The plane was at 6,000 feet and had just exited a storm area. The object remained stationary for a minute before disappearing. Although initially considered a UFO, investigators concluded it was likely a subsun caused by ice crystal reflections. The detailed description and the plane's location in specific weather conditions support this explanation. The incident, though not confirmed as an astronomical phenomenon, shows how atmospheric conditions can create convincing optical illusions.
