Produced by the Germans, the Fokker D.VIII is considered to be one of the best fighter planes produced by anyone during WWI. The Fokker D.VII aka the Fokker E.V. was given the name "the Flying Razor" by the Allied troops because of its effectiveness in battle. The Fokker had an advantage because of its maneuverability and the synchronized machine guns that would fire through the propeller without shredding the thing to bits.
