David's books should be required reading for all military personnel of all branches.
I loaned Their Greatest Disgrace to two friends of mine at the time. They were both retired RAF engineers, one a Group Captain and the other a Squadron Leader. I am pretty sure that the former didn't read it, the other went and bought his own copy. A member of my family is a military helicopter pilot and he shows little interest in reading, or even talking about any of David's books. A decision to make them compulsory reading would require such a transformation within MoD it would make the current Post Office events look trivial.
