Here is a website that I thought was extremely interesting. Submariners, like helicopter pilots, are a quirky breed all their own (it's a volunteer service, you know - maybe not in WWII), but who over the age of 50 hasn't enjoyed "Run Silent, Run Deep" with Clark Gable and Burt Lancaster a zillion times? Great stuff for any action movie.
This website takes you on an interactive tour of the WWII fleet submarine, USS PAMPANITO. There are 18 different compartments that allow you to get a 360 degree panoramic view. All you need to do is to put your mouse on the picture and drag left or right, up or down. You can also 'zoom' with your scroll button. Each compartment is described just below its picture.
