July 26, 1952 — Williams, CA
5:15 p.m. Air Defense Command radar detects a UFO over Williams, California. An F-94 jet interceptor is scrambled and locks onto the object with its radar. The crew sees a yellow-orange light. As confirmed by ground and airborne radar, the UFO plays tag with the F-94, alternately accelerating away when it gets close, then slowing down until it catches up again. [Eberhart]
