Shot Down by Mistake? of Su-15 Taking Down Boeing 747 (KAL 007)

Korean Air Lines Flight 007 was a Boeing 747-230B registered HL-7442, operating from New York to Seoul through Anchorage. On September 1, 1983, the aircraft deviated substantially from its intended route and entered Soviet-controlled airspace. Soviet air-defense forces treated the unidentified aircraft as an intruder.

The aircraft had departed Anchorage for the final leg to Seoul. The route deviation carried it toward areas of the Soviet Union that were heavily protected because of their military importance. Soviet radar detected the aircraft and fighter interceptors were sent to investigate.

The interception developed in darkness. Communications among Soviet ground controllers and interceptor pilots became part of the later historical record. The Soviet side ultimately ordered the aircraft destroyed. A Soviet Su-15 interceptor launched air-to-air missiles against the Boeing.

The attack occurred while KAL 007 was cruising at roughly 35,000 feet. The first missile detonated close to the aircraft, producing major damage including rapid cabin decompression and damage to flight-control systems. The aircraft did not immediately fall from the sky. Recorded flight data showed a climb followed by a prolonged descent sequence.

The aircraft's crew continued communicating for a short period after the attack. The flight later descended over the Sea of Japan near Moneron Island. All 269 people aboard were killed.

The historical record separates two questions that are sometimes merged. First, why did the civilian aircraft enter Soviet airspace? Second, why did the Soviet military decide to destroy it? The ICAO investigation examined the navigation deviation and concluded that the aircraft had departed its assigned course. The Soviet decision to use force occurred within the context of Cold War air-defense operations and the identification of the aircraft as a threat.

The event remains one of the most consequential examples of how a navigation error can intersect with military airspace and produce consequences far beyond ordinary flight operations.
