JTO:-
the Coroner has primacy and is powerful enough to work through any MoD static.
Well history, as testified to by tuc, would seem to disagree. If an air regulator tells a coroner at a pre inquest hearing into a fatal aircraft accident that the aircraft was both serviceable and airworthy he has little alternative than to accept that as a fact. The problem isn't with the coroner or PF per se, the problem is the MOD, which consistently lies, steals, and cheats. We can be certain that as long as it remains air regulator, investigator, and operator combined (via its 'independent' subsidiaries; the MAA, the MAAIB, the RAF, the FAA, the AAC) it will go on doing so.
Every fatal accident that has been reviewed in this forum is presented by the MOD as unique. In truth they are all connected by this very contradiction, that of self regulation. It doesn't work, and in aviation it kills.
