Glenn Curtiss
To ensure the safety of people in the air and on the ground, early aviation soon required that aircraft be under the operational control of a properly trained, certified pilot at all times, who is responsible for the safe and legal completion of the flight. The Aéro-Club de France delivered the first certificate to Louis Blériot in 1908—followed by Glenn Curtiss, Léon Delagrange, and Robert Esnault-Pelterie. The British Royal Aero Club followed in 1910 and the Aero Club of America in 1911 (Glenn Curtiss receiving the first).
