Oct. 14, 1973; Marion County, Mississippi
A Marion County civil defense official reported an unidentified flying object knocked out his radar Sunday night. James Thornhill of Columbia said he picked up an object on his radar set. "I observed what I thought to be an aircraft," Thornhill told officials. "It got rather close to the station, about three miles, then it became stationary and all of a sudden my radar just completely jammed. "I've never seen anything quite like this, except perhaps during World War II," he said. Thornhill said the radar unit developed streaks when the UFO returned later. Area residents, he said, reported seeing a craft with bright blue lights Sunday night.
