Moneron Island
On 1 September 1983, Korean Air Flight 007, a South Korean civilian airliner, flew over Sakhalin and was shot down by the Soviet Union, just west of Sakhalin Island, near the smaller Moneron Island. The Soviet Union claimed it was a spy plane; however, commanders on the ground realized it was a commercial aircraft. All 269 passengers and crew died, including a U.S. Congressman, Larry McDonald.
