🇺🇸 USAF — Project Blue Book
In August 1956, a witness in Yellow Springs, Ohio reported a reddish object moving vertically every six minutes. Although no photos or radar were used, the intelligence officer concluded it was the planet Mars. The size, color, and trajectory matched known characteristics of the planet. However, the periodic movement raised some curiosity. Ultimately, the case was closed after confirming no unexplained elements.
