crash trajectory
From the pictures shown on this thread it is not a confirmed fact that the aircraft hit first where the skid marks are visible on the hill. Maybe it hit first at a location not shown and bounced off into the hill shown on the fotos, shedding its tail at the first strike which then travelled a bit further.
It would also be helpful to know the day-time these heli pictures where taken, because the shadows would give a clue to the impact track of the aircraft.
