Every major country that fought in World War II has a museum dedicated to the international conflict, and The National World War II Museum is America's. Check out the rich collection of military artifacts and the interactive submarine, then get close to some original aircraft used in battle. The selection includes a B-17 Bomber and a P-51 Mustang with a red tail, just like the Tuskegee Airmen flew. Don't miss the Enigma code machine, a precursor to the modern computer.
