Awesome pics - was also looking for the TDC
The control room looks cramped - in Sh3 it felt so roomy. It also appears fairly room in Sh5. What I remember from being on the boat in Chicago (u-505 i think) was that there wasn't a ton of head room - in places I had to hunch a bit. In SH3 and SH5 there appears to be a ton of head room - like a good two feet.
