I really liked the book. It went beyond just talking about the AFC to get into some of the minutiae of life in the RFC / AFC, and I eat that stuff up!
By the way, have you got a copy of "Canada's Fighting Airmen" by LCol George A Drew? I recently saw a signed 1930 first edition. At about $105 Canadian (@$85 US) it wasn't worth it to me personally. The book's a bit of hero worship so it's historical rubbish, but it's a lovely book. If you're interested, I can see if it's still there in a used book store in Saint John, NB.
