Good Post, dervish. Thank you! I take it that the book you refer to is Their Greatest Disgrace by David Hill. It describes the systemic failures that were deliberately created by RAF VSOs in the 80s/90s and that infect the UK Military Airfleet to this day (including ACO gliders!).
It also describes the systemic cover up of those VSO actions which prevents proper reform of UK Military Air Accident Investigation and Regulation to this day. This accident was the most costly airworthiness related UK Military Air Accident but by no means the only one. 74 deaths have featured in military airworthiness related air accidents in this forum alone.
Self Regulation Doesn't Work and in Aviation It Kills!
