July 20, 1964 — Clinton, IA-Littleton, IL
4:45 a.m. Joseph J. Winkel is driving east through a wooded area on State Highway 101 about 2 miles west of Littleton, Illinois. He notices a shadowy, cone-shaped object about 60 feet in diameter with reddish-purple flames coming from its end. It climbs to about 1,500 feet and levels off, coming directly toward him, then makes a sharp turn upward and nearly levels out again at 3,500 feet. The sparks turn bluish-yellow, making a ball of fire, and a few seconds later it shoots out of sight. Around the same time, a USAF Airman 1st Class sees a similar cone of light as he is driving east on US Highway 30 about 7.5 miles west of Clinton, Iowa. [Eberhart]
