Kurt Tank
In August 1941, RAF pilots reported encountering a very fast radial engine fighter over France. First thought to be captured French Curtiss 75 Mohawks, they turned out to be Focke-Wulf Fw 190s, slightly faster and more heavily armed than the current Spitfire V. Kurt Tank had designed the aircraft when the Spitfire and Bf 109 were the fastest fighters flying; he called them racehorses, fast but fragile. As a former World War I cavalryman, Tank chose to design a warhorse. With a BMW 801 radial engine, wide-set undercarriage, and two 20mm cannons as well as machine guns it became a better fighter-bomber than either of the pure fighters.
