It depends on how evidence is presented and what it sets out to prove, As you continually state there is no evidence except that the aircraft flew into a cliff at high speed in controlled flight. Because we have no flight recorders then the obvious must be discounted in case we upset the relatives. The AM's were not prepared to whitewash, basically they saw no possible explanation for this but for negligence on the part of the pilots. I think this was case, there is no evidence for the aircraft being out of control, it shouldn't have been where it was in those condirions and there are no mechanical issues that would force it on that course and at that speed.
