What gave rise to the question of a pressure release valve.
I read an account where the diesel engine was started in order to bring the U-boat to the surface. The E-motors were inoperative. The pressure in the U-boat dropped to below the atmospheric pressure once surfaced.
Under a vacuum, how does one open the hatch that is held down by the differential in pressure.
