The 1990 Wayne County Airport runway collision involved the collision of two Northwest Airlines jetliners at Detroit Metropolitan Wayne County Airport on December 3, 1990. Flight 1482, a scheduled Douglas DC-9-14 operating from Detroit to Pittsburgh International Airport, taxied by mistake onto an active runway in dense fog and was hit by a departing Boeing 727 operating as Flight 299 to Memphis International Airport. One member of the crew and seven passengers of the DC-9 were killed. Accident Northwest Airlines Flight 1482, a Douglas DC-9-14, was cleared from the gate toward Runway 03C, but it missed turning onto Taxiway Oscar6 and instead entered the outer taxiway. To correct the error, the crew were instructed to turn right onto Taxiway X-ray, but they instead turned onto the active runway, 03C. They realized the mistake and contacted air traffic control, which instructed them to leave the runway immediately. Five seconds later (at 13:45 EST), the crew saw the Boeing 727, Northwest Flight 299 to Memphis, heading toward them on its takeoff roll. The 727's wing cut through the right side of the DC-9's fuselage just below the windows, then continued aft, finally cutting off the DC-9's right-side (#2) engine. The DC-9 caught fire and was destroyed. The captain of the DC-9 escaped from the aircraft through the left sliding window. Eighteen people escaped the plane from the left overwing exit, 13 people escaped through the left main boarding door and four people jumped from the right service door. The rear jumpseat flight attendant and a passenger died from smoke inhalation in the DC-9's tailcone; the tailcone release was not activated, and later investigation determined that the release mechanism was mechanically inoperable. Of the surviving passengers, the NTSB stated that 10 received serious injuries and 23 received minor or no injuries. The three surviving crew members received minor or no injuries. The NTSB added that it did not receive medical records for three passengers who were admitted to a burn center; for purposes of the report, the NTSB labeled their injuries as serious. The NTSB also did not receive medical records for the copilot and six passengers who were treated and released from area hospitals; for the purposes of the report, the NTSB assumed that they had received minor injuries. After the collision, the 727 flight crew immediately initiated a rejected takeoff and was able to stop the aircraft safely on the remaining
