It is all very jolly having a pop at "procurement", which is sometimes deserved but not as often as you think, but one should ask whose job it is to specify and quantify what and how many of a given item is required. And who makes materiel and financial provision for the upkeep of airworthiness data and, ultimately, the Safety Case. And whose terms of reference, uniquely, grant authority to overrule on all these issues using "engineering judgement". For any given item in the inventory this is the same identifiable individual. In this case, an RAF post, and he/she doesn't work in "procurement" (because this is something you do before being promoted into procurement). And I wouldn't be surprised if he isn't an engineer, which is the root of many problems in this domain (noting that the current problem on gliding is precisely the same as forced the scrapping of MRA4).
