Maneuvering past that crank must have been quite an obstacle course. I've always assumed the center bench position was FILO...
For completeness: in the first sinking (partial crew, alongside [?Ft. Johnson?] dock, both hatches open, swamped by wake of passing vessel) bodies were clustered around both hatches. IIRC, one crewman [?Haskell?] escaped via the front conning tower, but the hatch trapped his leg and dragged him down quite a ways, before he finally freed himself...
Assuming those hatch covers are about 1.5 sq ft in area, that means that every foot of submersion adds about 100 lbs of force required to open one of them...
As you walk into the display area, there is a cabinet with eight or ten heads on two shelves,forensic reproduction made from skulls of the crew. Below each severed head is a little bio. It's interesting how most of the crew were ordinary people, and some of them recent immigrants, and not native born southerners.
