I agree that from the impact site and the limited pictures we have it is an enigma both regarding the apparent lack of forward speed as well as the distribution of debris (ie seats).
Let's hope the preliminary report will shed some light on this, so if someone comes across it, please let us know.
Some questions I have
Does anybody know (as opposed to suspect) the amount of damage an exploding O2 bottle would do?
Or would a protruding rock (perhaps a little away from the final resting place) rip of the nose and in the course of this energy absorption reduce the forward speed such that the plane just drops down wit more downward speed than forward speed?
The seems to be a little fire damage to the front possibly due to impact fire, but is it possible they had an electric fire and the pilot elected to attempt a stall crash landing against the ridge, not unlike our Biggles friend on the golf course and failed to time the stall and impact moment?
