🇺🇸 USAF — Project Blue Book
A witness in Michigan observed a rectangular white object, the size of a baseball held at arm's length, that remained nearly stationary in the sky. The sighting lasted one hour and twelve minutes, suggesting a detailed and prolonged observation. Although the object moved slightly, no photos were taken and the report came from a civilian. Investigators considered the possibility that it was a balloon, especially given the frequent balloon launches by the University of Minnesota and General Mills. These balloons often drift toward Saginaw, supporting the hypothesis that the object could have been one of them.
