SUMMARY OF FINDINGS AND CONCLUSIONS
On 31 August 1983, a Korean Air Lines (KAL) Boeing 747, designated KE 007, departed John F. Kennedy International Airport, New York, United States, on a one-stop scheduled flight for Kimpo International Airport, Seoul, Republic of Korea. The en-route stop occurred at Anchorage International Airport, Alaska, United States. At Anchorage, the aircraft was refuelled and serviced for the remainder of the flight to Seoul and, in accordance with company practice, the flight and cabin crews were changed.
The flight departed at the planned time of departure which, in keeping with Korean Air Lines' procedure, was calculated for each KE 007 flight. The departure from Anchorage was flexible to ensure arrival in Seoul at the scheduled arrival time of 21:00 hours* (06:00 hours local time). The actual departure time of 13:00 hours on 31 August would have resulted in an on-time arrival of KE 007 in Seoul, had the flight been completed in accordance with its flight plan.
On departing Anchorage, the flight had 269 persons on board consisting of 240 passengers, 3 flight crew members, 20 cabin attendants, and 6 crew members of KAL being repositioned to Seoul.
Soon after departure from Anchorage, KE 007 deviated to the right (north) of its direct track to Bethel. This deviation resulted in a progressively greater lateral displacement to the right of its planned route which, ultimately, resulted in its penetration of adjacent high seas airspace in flight information regions (FIRS) operated by the Union of Soviet Socialist Republics (USSR), as well as of sovereign USSR airspace overlying Kamchatka Peninsula and Sakhalin Island and their surrounding territorial waters.
No evidence was found during the investigation to indicate that the flight crew of KE 007 was, at any time, aware of the flight's deviation from its planned route in spite of the fact that it continued for over five hours. According to representatives of the United States, military radar installations in Alaska were not aware in real time that the aircraft was proceeding west with an increasing northerly deviation from the recognized airways system. The military radar installations of the Japanese Defence Agency were aware that an aircraft was tracking in USSR airspace over Sakhalin Island. According to representatives of Japan, they were not aware that it was a civil aircraft off its intended track.
Approximately between 16:40 and 17:08 hours military aircraft operated by the USSR attempted to intercept KE 007 over Kamchatka Peninsula. The interception attempts were unsuccessful. From about 18:00 hours when KE 007 was approaching Sakhalin Island, USSR, the flight was intercepted by USSR military aircraft. At 18:26:02 hours the aircraft was hit by at least one of two air-to-air missiles. fired by the pilot of one of the USSR interceptor aircraft who had been directed, by his ground command and control units, to shoot down an aircraft which they assumed to be a United States RC-135.
As a result of the attack, KE 007 collided with the sea and sank off the southwest coast of Sakhalin Island. There were no survivors. The flight recorders, fragmentary pieces of the aircraft and a small number of items of personal property were salvaged by divers from the USSR during a two- month period following the accident. In addition, some flotsam from the aircraft was dispersed by tidal currents and recovered later.
The cockpit voice recorder (CVR) and the digital flight data recorder (DFDR) tapes were recovered by the USSR in 1983 and were handed over to ICAO in January 1993 by the representatives
