Point taken, but what so few seem to grasp is that, for example, the same 2 Star was responsible for delivery of both Nimrod and Chinook - and was warned in great detail about the precise problems that would befall each programme. Same man happily ruled that airworthiness could be ignored if it meant delivering to time and cost (not that either of these programmes achieved that!). MoD is widely condemned for such procurement cock-ups, but actually it is down to the management ethos of a few individuals. Management sets the tone.
