Bast0n, I agree that "no doubt whatsoever" demands an extremely difficult (impossible?) set of of essential criteria to be met. However, those were the rules at the time and there lies the problem. Despite the full-and-frank exchange of views presented on this thread by the two camps, I think it is fair to say that many/most/all believe there is a significant/high probability that the crew got things wrong in some way. But, "believe" &"probability" do not fit with the burden of proof required for "no doubt whatsoever".
All that is required from the MOD is acknowledgement that this burden of proof was not met. We don't need to shoot off into other directions about PRC112 LZs, breakfasts, met briefs, or little green men. Airworthiness is a valid issue that needs highlighting as it extend across the MOD fleets and ZD576 (like Nimrod and C130) should be used as an example of this systematic failing.
