Was bored tonight so I searched the web for some stuff on the Atlantic war. Couple sights that mey be of interest if you have not already seen them are this one
http://www.mariner.org/atlantic/
Which has a good quicktime clip (in colour no less!) of the capture of U-505.
That lead me to look at the Chicago museum site where the U-505 currently sits. Take a good look around this site as it has lots of cool information.

It's been under restoration since 1997 but is now once again on display. I had the good fortune to stumble upon it when I was in Chicago in the mid 80's and took the tour. It was very impressive. If you have the chance to be in the Chicago area it is a must see. If memory serves me correctly they also have a Stuka hanging from the ceiling in the front lobby.
Edit, sorry about the inactive links, you'll have to copy and paste until I have a chance to fix them from my work computer. My Mac at home won't allow me to do so.
