The listed crash cause is terrorism act, hijacking, sabotage. 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 (FIR_s) 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 a\vare 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 t\\'o 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 of the Russian Federation. They also made available recordings and transcripts of the communications between the pilots of the intercepting fighter aircraft and their ground controllers as well as the communications between the command centres. The representatives of the United States made available certified copies and transcripts of the Anchorage ATC tapes, and the representatives of Japan made available the Tokyo ATC tape. In the course of the investigation, all practical steps were taken to confirm the authenticity of the communications tapes. A comprehensive assessment of the physical characteristics of the CVR and the DFDR tapes and the information recorded thereon was made to ensure that they contained authentic records. The material on the communications tapes and the CVR and DFDR tapes showed no evidence of contradiction with known information and correlated well with other sources of data. There was no evidence to suggest that the crew of flight KE 007 was aware that their aircraft was flying to the north of its planned route or that they knew of the presence of the intercepting fighter aircraft. The DFDR record established that flight KE 007 maintained a constant magnetic heading from soon after departure from Anchorage until the attack by the fighter aircraft. The maintenance of the constant magnetic heading was so accurate it could only have resulted from the autopilot controlling the aircraft. The CVR and the DFDR records also established that the aircraft did not sustain an extensive avionics or navigation systems failure or malfunction prior to the attack by the USSR fighter aircraft. The evidence obtained supported the first hypothesis of those listed in the 1983 ICAO report, Le. that the crew inadvertently flew virtually the entire flight on a constant magnetic heading. The maintenance of a constant magnetic heading and the resulting track deviation was due to the KE 007 crew's failure to note that the autopilot had either been left in heading mode or had been switched to INS when the aircraft was beyond the range (7.5 NM) for the INS to capture the desired track. Concerning the interception and associated identification, signalling and communications the investigation found the following: 1) Interceptions of KE 007 were attempted by USSR military aircraft over Kamchatka Peninsula and made in the vicinity of Sakhalin Island. 2) The USSR command centre personnel assumed that KE 007 was a United States RC-135 aircraft. KE 007's climb from FL 330 to FL350 during the time of the interception over Sakhalin Island was interpreted as being an evasive action, thus further contributing to the USSR presumption that it was an RC-135 aircraft. 3) No attempt was made by the USSR to contact the crew of KE 007 by radio on the distress frequency 121.5 MHz or on any other VHF or HF frequency. However, the interceptor pilot was instructed by his ground control to attempt to attract the attention of the crew of the intruding aircraft by firing his aircraft's cannon and flashing its navigation lights. It was not possible to assess the distance of the interceptor aircraft from the intruder nor their relative positions when the interceptor's lights were flashed and the cannon fired. 4) The USSR command centre personnel on Sakhalin Island were concerned with the position of the intruder aircraft in relation to USSR sovereign airspace as well as its identity. The time factor became paramount as the intruder aircraft was .about to coast out from Sakhalin Island. Therefore, exhaustive efforts to identify the intruder aircraft were not made, although apparently some doubt remained regarding its identity. .5) It was not possible to determine the position of KE 007 at the time of the missile attack in relation to USSR sovereign airspace.
