Agreed, the Hüttenwart (lodge keeper) at the Segnashütte said in his interview that the aircraft began a left turn before falling - for me a left turn would mean towards the pass / ridge as if attempting to make the crossing. No idea how close to the Tschingelhörner ridge side they flew though as they headed up that valley.
The Hüttenwart stated in another interview that he was inside the lodge and didn't see the crash personally, but others did. So the upcoming report will definitely give some information of the flightpath short before the accident.
