But I think the most badass bomber is the B-54 superfortress. It's like a flying battleship, where you man side guns and blast round after round of munitions at endless waves of Japanese Zero fighters trying to bring you down.
The floor of the flight deck will be filled with empty casings and the blood and guts of you and your dead crewmen, while most of the structure of the bomber is ripped from it's roots from anti-aircraft shells, but the tough son of a b**** is still flying.
