Like a lot of the factual Audible books I listen to, as soon as I was getting into it, I could not resist getting a hard copy - there was too much detail I knew I would want to go back to, even though it was still at a hardback price! That in itself is a complement to the quality and standard of the careful research that went into the book. The RAF got a better press than usual, as the German infantry also did not like being attacked from the air (no "superhuman" soldiers there) and the almost comical German command and control problems were highlighted.
Well worth the read if you can get it!
