We haven't, before or after this incident, had Chinooks throwing themselves into rocks and it is very very improbable that this one did
A few months ago someone provided a link to a report signed by the Inspector of Flight Safety that warned the Chief Engineer of just that. A series of crashes, some fatal.. The report starts by confirming these crashes were the reason why the report team had been established. I think Alcock has yet to explain what action he took, but as the Hadden-Cave report from a few years ago repeated the conclusions, the answer seems obvious. Can't understand anyone defending such incompetence.
