Korean Air Lines jet forced down over Soviet Union - Apr 20, 1978 - HISTORY.com

Soviet aircraft force a Korean Air Lines passenger jet to land in the Soviet Union after the jet veers into Russian airspace. Two people were killed and several others injured when the jet made a rough landing on a frozen lake about 300 miles south of Murmansk.

The jet was on a flight from Paris to Seoul when the incident occurred. Soviet officials claimed that the plane, which usually flew over the northern polar regions to reach Seoul, suddenly veered sharply to the east and penetrated Russian airspace. Soviet jets intercepted the passenger plane and ordered it to land. Instead of going to the airfield indicated by the Soviet jets, however, the KAL flight made a very rough landing on a frozen lake south of Murmansk. Two passengers were killed and several others were injured during the landing. A short time later, the Soviet Union allowed a civilian American aircraft to retrieve the survivors.

U.S. officials were confused about what had gone wrong with the KAL flight, and Soviet officials were not extraordinarily helpful in clearing up matters. South Korea claimed that “navigational errors” were to blame for the plane flying so far off course. Aviation experts, however, doubted that “errors” of that magnitude would occur in such a sophisticated aircraft or that navigation problems could account for the plane’s wildly inaccurate flight pattern. All that could be said for certain was that the episode once again demonstrated the Soviet Union’s strict adherence to the protection of its airspace. Since the end of World War II a number of civilian and military aircraft had been driven away, forced to land, or shot down by the Soviet airforce. The Russian policy would have even more tragic consequences on September 1, 1983, when Soviet jets shot down KAL Flight 007 after it veered 300 miles off course and flew over the Soviet Union–nearly 270 people died in that crash.
