George Cayley gave us wings

Sir George Cayley is considered by many to be the first scientific aerial investigator and the first person to understand the underlying principles and forces of flight. An engineer, inventor and aviator, he built a functional aerial device, a model helicopter with contra-rotating propellers, in as early as 1796.

Over the years, he went on to make many more contributions to the progress of aeronautical science, including the concept of the fixed-wing flying machine and the four forces that act on a heavier-thanair flying machine (weight, life, drag and thrust). Today’s advances in aeronautics are built on the strong foundation
of his work.
