Orca, it is not the sharing of typists that concerns me, it is the fact that typists, investigators, and regulators come under the same umbrella, ie the MOD! Before you point to your wiring diagram to show that they bypass the CoC and are answerable only to the very top of the tree, much the same was said of the old RAF Inspectorate of Flight Safety. No-one in the CoC could intercept and subvert the safety system we were told. That held good until the Inspector ordered the various ARTs to be produced; Chinook, Tornado, Hercules, etc, etc, and uncovered severe airworthiness shortcomings across the RAF Airfleets. Somehow this supposedly inviolate system was violated, to the extent that the reports were pulped (but not entirely thanks to those who hung onto their copies) and the Inspectorate 'disappeared'. So much for notion of independence within the MOD!
