Korean Air Lines Flight 007.
~6 min read · Ch. 1 of 5
On the morning of the 1st of September 1983, a Boeing 747-230B jet airliner departed from Anchorage International Airport in Alaska. The aircraft was bound for Seoul, South Korea, carrying 269 souls including passengers and crew. Captain Chun Byung-in sat at the controls with First Officer Son Dong-hui and Flight Engineer Kim Eui-dong. Less than ten minutes after takeoff, the plane began to drift northward off its assigned route toward Bethel. The autopilot system remained locked in HEADING mode instead of switching to INS mode as required for the long-distance flight. This single technical oversight caused the aircraft to fly hundreds of miles into Soviet airspace without the crew realizing their error. The inertial navigation computer had been armed but never captured the correct course line because the plane had already deviated too far. Air traffic controllers monitored the flight on radar but failed to notice the divergence until it was too late. The aircraft passed Cairn Mountain about west of Anchorage while still flying on a constant magnetic heading of 245 degrees. By the time the plane reached the Kamchatka Peninsula, it was well inside restricted Soviet territory. The crew requested clearance to ascend to a higher altitude for fuel economy reasons, unaware they were violating international borders. Their failure to detect the navigational mistake persisted throughout the entire journey from Anchorage to the point of impact near Sakhalin Island.
Soviet Interception And Shootdown Sequence
At 18:26 UTC, Major Gennadiy Osipovich piloted a Sukhoi Su-15TM Flagon-F interceptor toward the unidentified Boeing 747. Four MiG-23 fighters had scrambled earlier to intercept the airliner but ran out of fuel before making contact. Osipovich fired warning shots with his cannon, releasing more than 200 rounds of armor-piercing shells that likely did not register visually in the darkness. The Soviet pilot later recalled seeing blinking lights and two rows of windows, confirming he knew this was a civilian aircraft. Despite recognizing the passenger nature of the target, ground controllers ordered him to destroy the intruder. At 18:26:02 UTC, the first K-8 air-to-air missile detonated behind the Boeing, sending fragments forward through the fuselage. A second missile struck seconds later, damaging hydraulic systems one, two, and three while leaving system four intact. The autopilot disengaged automatically as the plane began an upward arc due to damaged crossover cables between elevators. The aircraft climbed from flight level 330 to 350 before descending again. Crew members reported engines were normal even after the missile strikes. The Boeing continued flying for nearly five minutes under limited manual control before spiraling downward over Moneron Island. Final cockpit voice recorder entries occurred at 18:27:46 while the aircraft descended rapidly toward the Sea of Japan. The jet broke apart mid-air and crashed into ocean waters west of Sakhalin Island. All 269 people on board perished instantly or within moments of impact.
