October 3, 1951 — Okinawa, Japan  
10:27 p.m. Three radar operators, Sgt. Melvin W. Watson, Pvt. Manuel M. Gonzales, and Senior Radar Mechanic Sgt. James E. Biscanto, north of Kadena AFB on Okinawa, Japan, track a large, sausage-shaped blip traveling at 2,400 to 4,800 mph from north-northeast to north-northwest at a distance of 60 miles. The radar site attempts to radio its report to Itasuke AFB, but it is blocked by heavy interference. [Eberhart]
