Détails:
Northwest Flight 255 departed Saginaw for a flight to Detroit, Phoenix and Santa Ana, arriving at Detroit (DTW) at 19:42. Pushback for departure was accomplished at 20:34 and the crew received taxi instructions for runway 3C. During the taxi out, the captain missed the turnoff at taxiway C and new taxi instructions were given. At 20:42 Flight 255 was told to taxi into position on runway 3C and hold, followed by a takeoff clearance two minutes later. Shortly after rotation the stick shaker (stall warning) activated. The aircraft rolled left and right and the left wing struck a light pole in a car rental lot. Flight 255 continued to roll to the left, continued across the car lot, struck a light pole in a second rental car lot and struck the side wall of the roof in a 90deg left wing down attitude. The plane was still rolling to the left when it impacted the ground on a road outside the airport boundary and continued to slide along the road, striking a railroad embankment, disintegrating and bursting into flames.

PROBABLE CAUSE: "The flight crew's failure to use the taxi checklist to ensure that the flaps and slats were extended for take-off. Contributing the accident was the absence of electrical power to the airplane take-off warning system which thus did not warn the flight crew that the airplane was not configured properly for take-off. The reason for the absence of electrical power could not be determined."
