June 21, 1952 — Oak Ridge, TN
10:58 p.m. A Ground Observer Corps spotter at Oak Ridge, Tennessee, sees a small (6–8 inches in diameter), slow-moving UFO near the AEC plant. GCI radar obtains the target, but it fades from the scope. An F-97 on combat air patrol engages in a “dogfight” with the object, which makes “ramming attacks” at the aircraft. It blinks until it speeds away. [Eberhart]
