Heinkel's He 219 Uhu is undoubtedly one of the most advanced aircraft to emerge from World War II. Conceived solely as a gun platform to serve as a defensive night fighter, the plane featured a bubble-top cockpit that was well forward, affording the pilot superb visibility. The cockpit was equipped with ejection seats, and was exceptionally well laid out. All controls were easy to reach and identify. Combined with the tricycle landing gear, this plane was truly a "pilot's aircraft" and was very easy to fly. It was stable and predictable, exactly what one would expect from a plane with the Uhu's intended purpose. The earlier versions were adequately powered by the Daimler-Benz DB 603A, and had good rates of climb and acceptable top speeds approaching 400 mph. However, later versions of the He 219 were much heavier, and because the more advanced, powerful engines were in short supply, these variants suffered in performance.
