July 24, 1957 — Nemuro Strait, north of Hokkaido, Japan
Russian antiaircraft batteries on the Kuril Islands, Sakhalin Oblast, Russia, in the Pacific Ocean open fire on luminous, fast-moving UFOs. No hits are made. The US claims it has no aircraft in the area. However, at 10:00 a.m., two USAF pilots flying F-86s are scrambled to intercept a disc-shaped object over the Nemuro Strait, north of Hokkaido, Japan, that is tracked by ground radar and seen by ground witnesses. [Eberhart] This case seems to originate in the AF Academy handbook chapter on UFOs. Not sure what their source is. BB Files have not been found.
