AXXCHOR,
It kind of reminds me of the after battery compartment. Thats where most of the crew members berth. Also that is where the enlisted mens ****ters were. Now mind you the toilets were right next to the water tight door between the after battery and the forward engine room. Soooo while sitting on said ****ter and if someone opened the watertight door while surfaced, that same sound and whoosh of air would blow right by your ol arse as you were sitting there. Coming straight down from the bridge hatch, through the Conn, Control room, Mess, and ****ters. God forbid you opened the valve to the santitary tank at the same time as the hatch opened. You were in for a long clean up.
Now that is the sound you would hear on a US Fleet Boat......on a U-Boat that could just be Bernard farting........
