I have just finished the revised and updated book. A revelation, more so than the original if that is possible. Why were the new images it includes from the crime scene not in MoD's report? The one with XX177's drogue shackle, next to another, shows just how much effort was required when overtightening the nut and bolt. The image of properly assembled shackles shows just how much clearance was built in to the design. And Martin-Baker supplied a special tool kit, with the correct spanners, which was not used. Instead, a socket and ratchet wrench. How the hell did this get left out of the report? Highly recommended.
