1799-1850's - George Cayley - Gliders

Sir George Cayley is considered the father of aerodynamics. Cayley experimented with wing design, distinguished between lift and drag, formulated the concepts of vertical tail surfaces, steering rudders, rear elevators, and air screws. George Cayley worked to discover a way that man could fly. Cayley designed many different versions of gliders that used the movements of the body to control. A young boy, whose name is not known, was the first to fly one of Cayley's gliders, the first glider capable of carrying a human.
For over 50 years, George Cayley made improvements to his gliders. Cayley changed the shape of the wings so that the air would flow over the wings correctly. Cayley designed a tail for the gliders to help with the stability. He tried a biplane design to add strength to the glider. George Cayley also recognized that there would be a need for machine power if the flight was to be in the air for a long time.

George Cayley wrote "On Ariel Navigation" that showed that a fixed wing aircraft with a power system for propulsion, and a tail to assist in the control of the airplane, would be the best way to allow man to fly.
