How did George Cayley build his glider?

George Cayley built his glider by designing a lightweight structure that incorporated a fixed wing and a tail, which were pivotal for stability and control. He used materials such as wood and cloth to create the framework and covering of the glider. Cayley's understanding of aerodynamics allowed him to shape the wings for optimal lift, leading to successful flights that laid the groundwork for future aviation. His innovative approach marked a significant advancement in the development of heavier-than-air flight.
