Voss was the most competent flyer and tinkered with his machines to improve performance even going as far, at one point, as to use a captured French engine from a plane he forced down, but he was young and reckless. Richthofen was a stealthy hunter and opportunist in the air. Its interesting to note the the Baron, who was of the German nobility was a close friend of Voss who was a young Jewish kid who loved motorcycles and flying.
