Korean Air Lines Flight 007

Korean Air Lines Flight 007 was a scheduled Korean Air Lines flight from New York City to Seoul via Anchorage, Alaska. On September 1, 1983, the flight was shot down by a Soviet Sukhoi Su-15TM Flagon-F interceptor aircraft. The Boeing 747-230B airliner was en route from Anchorage to Seoul, but owing to a navigational mistake made by the crew, the airliner drifted from its planned route and flew through Soviet airspace. The Soviet Air Forces treated the unidentified aircraft as an intruding U.S. spy plane, and destroyed it with air-to-air missiles, after firing warning shots. The South Korean airliner eventually crashed into the sea near Moneron Island west of Sakhalin in the Sea of Japan, killing all 246 passengers and 23 crew aboard, including Larry McDonald, a United States representative. It is the worst Korean Air disaster to date.

The Soviet Union initially denied knowledge of the incident, but later admitted to shooting down the aircraft, claiming that it was on a MASINT spy mission. The Politburo of the Communist Party of the Soviet Union said it was a deliberate provocation by the United States to probe the Soviet Union's military preparedness, or even to provoke a war. The U.S. accused the Soviet Union of obstructing search and rescue operations. The Soviet Armed Forces suppressed evidence sought by the International Civil Aviation Organization (ICAO) investigation, such as the flight recorders, which were released in 1992, after the dissolution of the Soviet Union.

As a result of the incident, the United States altered tracking procedures for aircraft departing from Alaska, and President Ronald Reagan issued a directive making American satellite-based radio navigation Global Positioning System freely available for civilian use, once it was sufficiently developed, as a common good.
