To make my reasoning more understandable (for the doubtfuls):
This is a wreckage where pasengers can walk away (if they are lucky):
Atlasjet 4203
btw noone survived...
This is the wreckage where there is no big chance of survival:
Kegworth
btw 47 survived the crash.
Basically the chance of survival of a crash is a function of g forces. There is also the question if there are evacuation possibilites and fire or smoke.
If your G forces are too high, your body will be destroyed. So now compare these two pictures with the wreckage in AMS, and you can clearly see that primary structures were relatively intact, that the passenger floor with it's seats stayed in place and that there where a lot of survivers.
So this should be a clear evidence that this aircraft didn't fly below stalling speed, that the ROD wasn't very high. Compare post
Post 445 for information of the very similar SAS accident (everybody survived).
