Actually, I think that was the original poster's idea. I noticed that all the vehicles he mentioned were either flying or naval. Sounds like an interesting twist. I can also imagine a fictious world like that. Kind of like a wierd combination of two types of Pirates as the blunt of entire forces. A mixture of the Pirates of the Carribean and Disney's Tailspin (Or Crimson skies, take your pick). In one case, you had official battle forces and pirates at sea, the other case, it was all in the air.

Of course, perhaps someone can be really twisted and actually do that verbatim. The thought of researching a Spanish War Galleon and the Sea Duck class cargo plane at the same time has so many "wrong" things about it, that it could be quite popular. It's twisted stuff like that that makes stuff like Red Dwarf and Army of Darkness.
