Here is a German U-Boat passing under the Brooklyn Bridge:

Being hauled out of Lake Michigan:

They dragged it accross Lake Shore Drive to the Museum:

It felt cramped with a tour group of about a dozen. I can't imagine being in that thing fully provisioned for a war cruise with a full crew.
There is an Enigma in the Imperial War Museum in London, but I can't remember now if they had one or both types.
Very interesting. Thank you.
I find those old submariner shows fascinating. Actually, anything deeps sea, the animals, plants, formations, ship wrecks - all fun to watch on TV.
Now that you show me those pics, I do remember that a spur line still existed right up underneath the sub. That would have been, hmm, late 60s, early 70s?
