How One Engineer’s “Stupid” Wing Shape Made the P-51 Outmaneuver Every German Fighter

North American Aviation's P-51 Mustang revolutionized WWII air combat through Edgar Schmued and Ed Horkey's ingenious use of the NACA 66-series laminar-flow wing, which moved maximum thickness aft to dramatically reduce drag at high speeds. While true laminar flow proved elusive in combat conditions due to bugs, rivets, and paint imperfections, the advanced airfoil design still slashed drag enough to push the Merlin-powered Mustang to 440 mph while maintaining performance at altitude. Combined with the innovative Meredith-effect radiator that actually generated thrust and long-range drop tanks, this "stupid simple" aerodynamic trick gave American bombers their first fighter escort capable of flying 1,000-mile missions to Berlin and back—finally turning the tide in the strategic bombing campaign.
