ShotOne,
OK, don't want to argue about this so perhaps we can agree to disagree on discussion of fatigue as a contributing factor. In my own simple mind, though, what I see is:
a) the aircraft crashed
b) it crashed because it hit the berm
c) it hit the berm because it wasn't going fast enough to take off
d) it wasn't going fast enough because thrust was insufficient
e) thrust was insufficient because....
and there, for the time being, it rests. Waiting for facts.
Cheers,
