First, apologies for dragging up an old thread. But I read this article in the November Sport Aviation today about a former Luftwaffe pilot, Gunter Voltz. Like many of his fellow Germans he came to the states after the war. He had 1800 combat hours in the Fieseler Storch. He said in the article "one reason the Germans were slow to develop helicopters was they didn't need them - they had the Storch."
