I've quickly scanned the recommendations in the two reports issued on the same day. Yep, seen them all before. Formal declarations made that the relevant regs had been met, when it seems much of the work hasn't started.
General Felton's rather pointed recommendations (WK043) amount to 'Now we've crashed 5 after the RTS was issued, let's think about issuing a legal RTS'. I wonder if he knows how many previous BoI/SIs have said this?
DG DSA (who certainly knows) excuses much due to complexity. The need for endorsed Aircrew and Operating Data Manuals isn't complex. It's bloody mandated. Incomplete understanding of how sub-systems integrate? I distinctly recall one person who later headed UAVs saying 'If it works on the bench, it'll work in the aircraft'. RTS signed with no integration, testing, trials, training, pubs, etc. Four years later, Tornado ZG710, 2 killed. At least the death count is now lower.
