Korean Airlines flight shot down by Soviet Union

In 1983, Korean Airlines (KAL) flight 007 ended up nearly 200 miles away from its expected destination where it flew into Russian airspace and crossed over the Kamchatka Peninsula, where some top-secret Soviet military installations were known to be located. The Soviets sent two fighters to intercept the plane who located the KAL flight and tried to make contact with the passenger jet. Failing to receive a response, one of the fighters fired a heat-seeking missile. KAL 007 was hit and plummeted into the Sea of Japan. All 269 people on board were killed.
