Korean Air Lines Flight 007 alternative theories concerns the various theories put forward regarding the shooting down of Korean Air Lines Flight 007. The aircraft was en route from New York City via Anchorage to Seoul on September 1, 1983, when it strayed into prohibited Soviet airspace and was shot down by Soviet fighter jets. One of the first theories was that Space Shuttle Challenger and a satellite were monitoring the airliner's progress over Soviet territory. Defence Attaché, which printed this claim, was sued by Korean Air Lines and forced to pay damages and print an apology.
