John,
I suspect that flipsters "too low" and "too fast" were referring to Bill Wratten's published view that the helicopter was travelling too low and too fast under the conditions "at waypoint change". i.e within 1.6Km of a fogbank over high ground. That, as far as I understand it, is the essence of the RO's argument. He also has argued that anything which may have happened after that is not relevant to that decision. Anyone remember his motorbike analogy?
It is that judgement which the Campaign are trying to reverse.
I find it interesting that, when two F15s did something similar, the RAF tried to blame their own ATCO.
