I accept your claims on what might have happened.
Facts, accepted by legal reviews, Government and (most of) MoD.
Your opinion on the present day is grossly out.
I guess it's time, then, to write to the new Cabinet Secretary and Head of the Civil Service, to ask if he agrees with his last 4 or 5 predecessors that refusing to obey an order to make a false declaration about airworthiness is an offence, and issuing the order is not. The last confirmation was on 28 October 2014, from the late Sir Jeremy Heywood, upholding a 22-year old ruling. Not a one-off aberation then. One briefed to him by MoD's DE&S Secretariat at AbbeyWood.
