May 21, 1949 — Moses Lake AFB / Hanford Atomic Works, Washington
1:30 p.m. An F-82 is dispatched from Moses Lake AFB [now Grant County International Airport] in Washington State to intercept a UFO that is hovering in restricted air space over the Hanford Atomic Works at an altitude of 17,000–20,000 feet. The silvery disc is seen from the ground at Hanford and on radar. Before the F-82 can take off, the disc speeds away faster than a jet fighter. It disappears from ground radar and the F-82 cannot locate it. [Eberhart]
