Let's take this to the serious and informative side. I'd recommend
German Air Attache
I strongly suggest everyone interested in how and why German WWII aircraft production decisions were made to read the Peter Riedel's account, German Air Attache as penned by Martin Simons. Peter was a glider champion and Lufthansa/SCADTA pilot who among his many record flights in foreign countries, entered and won the 1937 US Championship. Engaging and outgoing, he traveled America by sailplane, gaining very favorable publicity with his soaring flights over NY city and flying his glider over many states. As a result, he was named Air Attache and by carefully analyzing media reports and accepting invitations to visit factories, he developed very accurate analyses of the American production capability. When war broke out, he was returned to Germany, and being a friend of Ernst Udet, continued reporting as part of the Air Ministry. These were not well received, plus he became aware of concentration camp crimes. Unwisely, he shared his concerns with friends Hanna Reitch and Heini Dittmar. Shunted off to neutral Sweden, he found that his uncomfortable reports, his knowledge of unsavory events, as well as having married an American woman, when called back to Berlin, he went into hiding in late '44. His dodging to sail sketchy vessels to Casablanca, to South America, finally returning to the US via Canada is an adventure tale in itself ... full of subterfuge, mistrust and intrigue. He finally flew for PanAm and TWA before retiring. Most of the account is spent detailing the Nazi German mindset against inconvenient information, with a particular familiarity with attitudes of Goering, Milch, Canaris and many other key persons in the chain. All in all, a detailed, well footnoted and referenced accounting dealing with issues that many in this forum often guess about. Forgive me for not laying this out more cogently, but the site will not let my system use carriage returns, etc.
