Perhaps, now that the MOD, BAE and QuinetiQ face huge costs for compensation and legal fees, to say nothing of the cost of an airframe, the bean counters will realise that cutting costs because they can is not necessarily the cheapest option. But don't hold your breath.
My main concern now, is that in future, everyone will spend so much time covering their backsides that either nothing will ever get done, or it will run so late that the cost overruns will be huge.
