You repeatedly state that the MOD, MAA and MilAAIB must be separate and independent of each other. For civil aviation, the AAIB and CAA are independent of each other but both belong to the Dept of Transport and answer to the same minister. (Yes, EASA is an added layer, but it is DofT that acts on behalf of the State with EASA, not the CAA.)
Yes but in civilian aviation, the regulatory bodies (CAA, EASA, AAIB etc) are completely independent of the aircraft operators. This is not the case with the MAA.
