The Wayne County Airport runway collision was the name of a runway collision between two Northwest Airlines planes in dense fog at Detroit Metropolitan Wayne County Airport on December 3, 1990. It occurred when Flight 1482, a scheduled Douglas DC-9-14 service from Detroit to Pittsburgh International Airport, taxied onto an active runway by mistake in dense fog and was hit by a departing Boeing 727 operating as Flight 299 to Memphis. One crew and seven occupants of the DC-9 were killed.
