just saw a documentation about American Flight 1420 which overshot 4L in Dallas (I think). It was a MD80.
As I sure think many here have read and heard a lot about that accident and I really wondered how this accident could happen.
The weather was severe, close to unflyable (with a safety approach anyway), thunderstorms, gusts of 45kn over the airfield and crosswind 330 with 21 to a runway heading 40.
The crosswind exceeded the aircraft and airline specs for wet runways by far, as the limit was at 10kn crosswind for those conditions.
With that fact given, a difficult approach, windshear and the mistake of not arming ground spoilers therefore limiting braking efficiency, the accident was kind of predictable.
So? Why on earth did the pilots not decide to divert in the first place? With making the landing calculations, the crosswind condition alone would have been enough to easily decide to divert.
I know mistakes happen, but I wonder about the psychological fact behind their decision to try the approach? How could they forget all their training, all their procedures, all their limits and so on?
Please no "its just the way it goes bla bla bla" answers.
I really want to find out the psychological fact behind it.
