Hear, hear, cuefeye.
Before going into full repel boarders mode could I politely suggest just sitting on our hands and thinking this one out for a while? Every previous airworthiness related fatal accident thread on this forum has entailed a circling of the wagons at the very suggestion that VSOs were not only involved in that deficit of airworthiness but had been responsible for causing it, while others ensured that had been covered up and go on trying to do so.
Accepting that is the nettle that has to be grasped is necessary if you love the Royal Air Force, for defending the indefensible can have only one outcome, that is the continual spread of unairworthiness throughout the military airfleets, further airworthiness related accidents (often fatal), and further accident investigations that fail to detect it.
A system of investigation that has the premise that investigations must conform to what they may investigate and what they may not (and if they do that to be told "to wind their necks in"), is not fit for purpose. It is a measure of the rot when we are told that the DG MAA has commended this Report. He might well do so, for it diverts attention from the real cause of this accident, Gross Unairworthiness, for which he is responsible.
