With 50 warplanes from the major combatants, this is the perfect collector's book on WWII aircraft for military buffs.     From Germany's Junkers Ju 52 and Japan's Mitsubishi Zero to USA's Grumman Hellcat and the UK's Bristol Blenheim, Warplanes of World War II provides a close look at 50 key aircraft in service between 1939 and 1945. They come from both Axis and Allied countries, and all appear in a large-format side-view color photograph that shows every detail. Notes point out each craft's unique features, while in-depth description of the aircraft's development, manufacturing history, and technical profile accompany additional color photographs and a specification panel.
