The 1911 Curtiss Model D (or frequently the Curtiss pusher) was an early United States aircraft of a pusher-prop design with the petrol engine and propeller behind the pilot's seat. The basic aircraft model was among the very first aircraft in the world to be built in any quantity — all of which were produced during this trial and error era of explosive aircraft development and equally important parallel technical development in internal combustion engine technologies.
Made by Curtiss Aeroplane and Motor Company.
