That is great! The Airacobra was a cool plane. The engine was behind the pilot. It had roll down windows like a car. American pilots hated it but the Russians did well. One of their leading aces got most of his kills in the P-39. Bell's theory was that if the engine was in the center of the plane, it would be better balanced and a better dog fighter. This proved to be false. It would flat spin like a frizbee it you lost control.
