Wrathmonk, caz stated that even if a major emergency occurred after waypoint change the finding would still stand because they were "flying too fast". I am not asking him to defend the finding, I'm asking him what "flying too fast" means specifically, and how he knows that they were "flying too fast". Of course if anyone else can answer those questions it would be instructive. The more one probes into this BoI the more it seems that the pilots were hung out to dry on the evidence "modelled" by the manufacturer. Given that there is a very good chance that the aircraft crashed because of known deficiencies in ALL Chinook Mk2's, that evidence is suspect even before one studies the reliability of the data on which it was "modelled". It is at that point that I find I have very little faith in it whatsoever. It would be interesting to see what view an objective and fair Accident Investigation would make of it. That has yet to happen.
