Well thank you for such kind words, Courtney. The "accountability thing" is the very nub of it of course. If, for example, an independent MAA had given the go-ahead to the MOD to procure an IFF fit for the Tornado that was not fully integrated and had known failure warning issues, it would itself be liable to criticism in a subsequent IFF Related Fatal Air Accident Investigation report by an independent MAAIB. I have a suspicion that such accountability would tend to ensure that the fit would be got right first time round and even perhaps on time and within budget, though maybe that is expecting too much!
