DV, God forbid that all this is going to end up in the maw of the legal profession, the words Hell and freezing-over come to mind. I predict that the majority of the questions that Mike Smith poses above will go unanswered here, by the BoI, and certainly by the MOD. The core problem here, as has been said before is of a self-regulating, self-protecting and self-preserving system. It is broken, dysfunctional and beyond repair IMHO. It must be broken up and replaced with a system subject to external and independent authority. In short a Military Aircraft Airworthiness Authority. This must be done soon, for time is not on our side, and is of the essence. Further avoidable accidents must be avoided urgently.
