2:50 So that is why the Germans could not win the war ... they had the BBC broadcasting inside their subs! :-P
This sub looks like something from the 1950's, not the 1940's. The Nazis were at least 10 years of the Allies in almost every category from subs to aircraft.
Wow what is this hellish sound ? It was queter back in WWWII when the diesel was working?
