I saw a documentary on Discovery about a german u-boat that was sent from germany in middle of 1945 containing scientists, documents and parts of a nuclear bomb and uranium(?). This u-boat was on a top secret mission and only one man on th boat knew where they were headed: Japan. I missed some of the program but the u-boat arrived at Japan and it semed that the japs putte some of their scientists in the uboa too. Then by some reason they left Japan and headed back to Europe. I didn't get what had happened because i missed this part but when they heard on the radio that Germany had surrendered they surrendered to the USA. The americans continued the german research and could develop bombs that they used on Nagasaki and Hiroshima some months later. Did you know this because it's all new to me.
