"Combat Aircraft of WWII".  "The Complete Book of Fighters".  "Focke Wulfe Fw 190 In Combat".  "Messerschmit "O-Nine" Gallery" (mostly pictoral, great pics of 109s, also Me 209, 309).  "Stuka Pilot". "To War in a Stringbag"   "Samurai!".  "Wings of the Luftwaffe".  "War in the Air" (collection of chapters from various WWII and WWI novels by Stephen Coonts, still a good read).  "Roar of the Tiger" (one of the "Flying Tigers" books, several guys who served with em wrote books; this one is pretty good).  Cant think of anything else right now, I'll go through the bookcase tomorrow.  I know I have some stuff on Spitfires and Hurricanes around somewhere, as well as P51 books.
