Excellent.
But who determines who appears in court to answer? It seems to be MoD, and the judiciary and Coroner's Service roll over. One of the more obvious examples was at the Mull of Kintyre Fatal Accident Inquiry (into the deaths of the RUC and civilian MI5 officers - not the Service personnel - a subtlety which I know interests you). The families were looking forward to engaging with the Air Marshals, but they were a no show. The MoD QC immediately asked the Sheriff to confirm that, if the author of evidence was not in court, then that evidence could not be produced. He agreed. (Probably had to agree, if that is the law). This renders RA1210 meaningless.
Possibly the most senior officer to appear is Admiral Massey, at the Sea King ASaC mid-air inquest in 2007. His evidence was tainted straight away by claiming the Mk7 is a two-pilot aircraft, and that two pilots (even if there were two) render electronic sensors redundant. So, it didn't matter that they were degraded in one aircraft, and not switched on in the other. His evidence is relevant to this Red Arrows case, because it reveals serous ignorance of the concept of defences in depth. Flt Lt Cunningham's parachute was the final defence. Seldom is it mentioned that a number of other defences failed entirely. None were Martin-Baker responsibilities. They didn't fail by accident. Many were as a result of MoD's policy and practice of savings at the expense of safety. If you strip away defences, the outcome is easily foreseen.
