In the water, submarines aren't very impressive. But put them on land and WOW! Like this one at the submarine museum in Britain. PS to curators: They're easier to maintain as well. The USS Olympia (Admiral Perry's battleship flagship of the Great White Fleet that opened China to world commerce) and the WWII Becuna sub at Penn's landing in Philadelphia are wasting away sitting as they are in the briny water of the Delaware River estuary. Land them!
