Although occurring in the mid-1970s, the case has only recently been revealed. At the time of the event, the eyewitness was a college student at Emory's Oxford College.
After driving home to his hometown, he heard on the news about multiple sightings being reported in his area. These turned out to be a vapor trail from a rocket, but that was only the beginning. Check out this report at Disc-shaped UFO over Flowery Branch, Georgia, and comment if you so desire.
