🇺🇸 USAF — Project Blue Book
In September 1963, multiple witnesses in Murfreesboro, Tennessee, reported a stationary luminous object in the sky. The case was evaluated as possibly the ECHO I satellite. One observer described how the object alternated between disc and oval shapes with changing brightness. Other witnesses confirmed the object's presence, though it couldn't be definitively identified. The official evaluation pointed to a satellite, but other explanations weren't ruled out.
