🇺🇸 USAF — Project Blue Book
A group of civilians in Roseville, Michigan, observed a silver object with a round and cigar shape on April 27, 1952. They used high-powered binoculars and naked eye. The main object changed shape, dropped straight down, and stopped. Two additional cigar-shaped objects appeared in the area, disappearing quickly in opposite directions. No sound or formation was observed.
The report notes that the witnesses, with military backgrounds, ruled out weather balloons or conventional aircraft. The observation lasted 45 minutes, but no photos or altitude estimates were taken. Despite clear skies, the objects moved with surprising speed and maneuverability, leaving no trail. The responsible officer could not confirm the information's reliability but acknowledged the witnesses did not recognize the objects as conventional.
