Whilst I commend the comprehensive in depth knowledge of many people's knowledge of historical procurement processes, I do continue to get frustrated at the continual inference that so very many people are in on an enormous conspiracy to nobble every SI ever produced. Military aviation safety is full of very busy, well trained and experienced people working hard to look to the future and do their best. Whilst some people on these forums might have been around when decisions were made 20+ years ago, most of the key decision makers in MoD today would have been barely out of university or training. I don't disagree with many of the comments on these forums but how about debating how a performance based approach to safety might be applied to the modern military rather than criticising decisions made so many years ago.
