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 is 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 putopilot controlling th
