From my background, I was pointing out things that need to be looked at. It appears that the helicopter hit relatively vertical, as the main wreckage appeared to be somewhat contained. There did appear to be some minor wreckage scattering along the hillside, and the tail rotor appeared to be separated from the main wreckage. There are a lot of possibilities, and, not being part of the investigative crew, I cannot say for sure. There was another helicopter flying in the area taking pictures for the news while the first responders were on the scene.
