By all means identify the MoD's failings in getting a CWS solution implemented over the years, but this SI accurately and effectively identified the reasons behind this particular tragedy. There were multiple failings long before any CWS could have potentially affected the final outcome.
I'm all for pointing out the years of neglect, ignorance and malfeasance by the MoD/MAA in upholding the duty of care surrounding airworthiness, but don't conflate that fact with the assumption that every SI has been "nobbled" or lacked objectivity in any way. It does a huge disservice to those members of the SI who are as invested as anyone in preventing a reoccurrence of an entirely preventable accident.
