Book excerpt: Luftwaffe pilots of the Russian Front were the highest scoring aces of any aerial conflict in history. This book traces the careers of the pilots who flew the Fw 190 and the Bf 109 in the skies over Russia, and reveals how they achieved their remarkable successes. The Bf 109 was the most commonly used fighter on the Front, and saw action from Operation Barbarossa through to the Defence of the Reich in 1945. The Fw 190, meanwhile, proved itself to be arguably Germany's best piston-engined fighter, with many of its aces scoring over 100 kills.
