The one survivor was still in the fuselage which may have saved him ..... the other occupants were elsewhere ..... as I said earlier the 900 foot tumble down the mountain may have been more destructive than the impact ....
Survivor is in serious but stable condition .... probably the 6 hours he spent in the freezing cold would add to his complications
