1990 Detroit Metropolitan Airport runway collision

On December 3, 1990, two Northwest Airlines jetliners collided at Detroit Metropolitan Wayne County Airport. 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 Oscar 6 and instead entered the outer taxiway. To correct the error, the crew was 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 after being unable to release the tailcone emergency exit due to a mechanical fault.

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 runway. The captain then shut down all three engines and ascertained that no one on board had been injured and that the aircraft was only lightly damaged. Deciding that no immediate danger existed, he did not order an emergency evacuation, and the passengers and crew deplaned using the rear airstair after the aircraft was sprayed with fire retardant foam as a precaution. The 727 sustained a damaged wing and was later repaired.
