1) For anyone with an interest in the subject, they may want to read this book. I first borrowed a copy from the library, and later purchased one for my own small collection on Bomber Command.
University of Toronto Press ( 2009 )
( As most know, the RCAF was part of RAF Bomber Command. )
"The Science of Bombing illustrates how science was exploited by the Royal Air Force in the Second World War through the creation of Bomber Command's Operational Research Section, and represents a far more detailed examination of this important subject than anything previously attempted. The author also challenges some of the more enduring critiques of the Commander-in-Chief of Bomber Command, Air Chief Marshal Sir Arthur Harris, and demonstrates that he was in fact a very innovative and flexible commander.' (Sebastian Ritchie, Air Historical Branch, Royal Air Force )"
2) Another book I have found helpfull is: "The Development of RAF Strategic Bombing Doctrine, 1919-1939" by Scot Robertson. Mr Robertson is ( or was? ) an analyst in the Force Development Branch of the Department of National Defence in Ottawa
