What????? Wreckage just tells you where it hit the mountain and what direction. Nothing else.
Look, if you don't know anything about accident investigations it is better just to keep silent than post such rubbish. One can tell a great deal more than that from a crash site. Without a CVR or FDR it might be more difficult to point to a direct cause but if nothing else the accident scene should be able to eliminate possibilities.
In any event, the press is reporting that they were in last contact with tower at 11K. What was said has the potential to be rather enlightening, methinks.
