I just found a nice (but tragic) clip on Youtube commemorating the "Lusitania" sinking. I might like to use something similar to replace the starting menu movie. After all, a bunch of swarthy American sailors will look a little bit out of place in a WWI mod.
Oh, and one quibble - in the movie at 1:00 it looks like U-20 has two torpedo tubes on her starboard side, implying a total of 4. My sources indicate she had only two forward TT.
