🇺🇸 USAF — Project Blue Book
A round, silvery white object was observed over Rockford, Michigan, in October 1958. Described as the size of a golf ball, it remained stationary in the sky for 30 minutes. Although no photos were taken, the report concluded it was likely a balloon. The description and behavior of the object matched typical characteristics of such devices, suggesting it was not a conventional aerial or astronomical phenomenon.
