他和佩蒂特一定没有仔细读过波音公司的手册，上面明文写着在雪天禁止使用反推力倒车，否则会把地上的冰雪吹到机翼上破坏机翼形态。

问题好像是出在发动机使用反推力会将冰雪吸进发动机内，从而造成了加速上不去。

Reverse thrust was not a proper procedure at that time, hot exhaust could melt show and create ice in any number of locations on the plane, including along the leading edge of the wings.

After the engines were shut down and a mechanic inspected the engine inlets, however, he stated that no ice, snow, slush, or water was evident.

The crew attempted to back away from the gate using the reverse thrust of the 737's JT8D engines, which proved futile and evidently resulted in the engines ingesting ice and snow.

The National Transportation Safety Board determines that the probable cause of this accident was the flight crew’s failure to use engine anti-ice during ground operation and takeoff, their decision to take off with snow/ice on the airfoil surfaces of the aircraft, and the captain’s failure to reject the takeoff during the early stage when his attention was called to anomalous engine instrument readings. Contributing to the accident were the prolonged ground delay between deicing and the receipt of ATC takeoff clearance during which the airplane was exposed to continual precipitation, the known inherent pitchup characteristics of the B-737 aircraft when the leading edge is contaminated with even small amounts of snow or ice, and the limited experience of the flightcrew in jet transport winter operations.
