🇺🇸 USAF — Project Blue Book
A witness in Clinton, Iowa, described a luminous object shaped like an inverted cone emitting reddish and purple flames. The phenomenon was observed for about 45 seconds at an estimated height of 7,000 feet. The object ascended rapidly, made a sharp turn, and headed east before disappearing. The report, submitted by an employee of the Selective Service System, was deemed unidentified after an initial evaluation. The detailed testimony includes descriptions of the object's shape, color, and movement, as well as the observer's perception that it might be a rocket with an unusual fuel mixture.
