During the 19th century, George Cayley in England established the principles of modern aeronautics: lift, weight, thrust, and drag. He built the first true glider that carried a person a short distance. Later, Otto Lilienthal in Germany made over 2,000 glider flights and proved that curved wings generate more lift. His fatal crash in 1896 did not discourage others; instead, it provided valuable data.

Leonardo da Vinci (1452–1519) produced over 500 sketches related to flight. His ornithopter , a machine with flapping wings modelled after birds, was never built in his lifetime, but its technical precision astounded later engineers. Da Vinci also studied airflow and the centre of gravity. Nevertheless, he recognised that human muscle power alone was insufficient for sustained flight. His greatest contribution was shifting the idea from pure fantasy to a scientific problem. Later, Otto Lilienthal in Germany made over 2,000
