During World War II, the Savannah aircraft industry produced B-17 Flying Fortress bombers at the Savannah Army Air Base.

There are- P-51 Mustang (American); Spitfire (British); Zero (Japanese); TBF-1 Avengers; B-25 Bombers (American); B-17 Flying Fortress (American).*NOTE- The Bombers that started with "B-25, B-17, etc.... were made by the American company Boeing, which still exists today.*Some of the new Boeing planes include the 737,747,757,767,777,787 (Dreamliner) and other bombers that the American Military uses. Sometimes these bombers are on display at airshows i.e.- Wisconsin airshow which I believe is in May or around that time of year. Please don't quote me on the exact dates of that Airshow, but if you were to go to google.com and search the dates, or "Wisconsin Airshow", you might find the official link there.
