June 22, 1952 — Pyeongtaek, South Korea
10:45 p.m. Two US Marine sergeants see a 4-foot diameter orange object dive at a runway from the north, dropping from 800 to 100 feet altitude over the west end of the runway at Pyeongtaek military base, South Korea, shooting 2–5-foot red flames. It then heads west at about 300–450 mph for 2–3 seconds, hovers briefly over a hill, turns 180° in 45–60 seconds, flashes, heads east a half mile, flashes again, and blinks out. No sound. [Eberhart]
