1. This Mk of Chinook was put into service when it was not fit for such service. Definitely yes
2. The RAF hierachy (that is to say CAS, CinC, AOC, and their staffs) knew full well that it was not fit to enter service but nevertheless insisted that it be flown. Possible, or they may have been merely ignorant and incompetent.
3. When the Chinook crashed into the Mull, the heirachy decided to blame two innocent pilots in order to conceal their own failings. Apparently yes, given any other plausible reason to overide the findings of the BOI, and the failure to comply with relevant regulations.
4. This view was supported by the Air, Flight Safety, Engineer and Legal Saffs at Group, Command, AFB and MOD levels See 2 above
5. Since then, no whistle-blower at any level has dared to put his head above the parapet to expose this conspiracy. Nonsense.
