File this under cool. Divers off the coast of Hawaii have found a Japanese WWII sub- make that a Japanese AIRCRAFT carrier sub. The submarine has "three fold-up bombers inside a watertight hangar, plus parts to construct a fourth airplane.". This one was custom built to drop disease bombs on the US eastern seaboard, but when the bombs weren't ready in time, they switched it's mission to bombing Panama instead, which would no doubt slow down the march of ships to Japan.
