Well consider that we don't like publishing the real data about our own AC and then that we like to make the other guy think we don't really know anything accurate about their stuff. Kinda like the official speed and range of the SR-71 vs what it really is. When the pilot of the current world record flight was interviewed and asked what they would do if the record was ever broken he was quoted as saying, "We'll just push the throttles forwards a little more."
Hey good luck with the swat.
As for the info I'm looking for I'm thinking it shouldn't be much harder to get than a non-american high school history text book. I mean hell just consider what a japanese history text would say? Hell if you are interested in seeing a different view of the war nithe atlantic what Da Boot. Very interesting to see a post WWII film, made ni germany, about the a U-boat. For some good contrast make a bit of a marathon of it and first watch a few american submarine movies from just after the war.
I also CAN recommend to you a book called
Blood and Water by Dan Kurzman. It was a great read. It is a barely novelized true story. Check it out. In fact looking through amazon I think I see a few other books of this guys I might read. Although he is an american author I can tell you for sure that Blood and Water is anything but American-centric.
