On August 29, 1945, an American B-29 pilot on a POW supply mission over northern Korea, refused to land on a Soviet-controlled runway, claiming it was "too short."

When he, instead, flew his B-29 (called the Hog Wild) out to sea, two Russian Yaks pursued him out to sea and fired at the plane, bursting the plane's engine on fire, causing the pilot to make a forced landing on the Soviet airfield.
