Sir George Cayley discusses the concept of aerial navigation, inspired by the success of a watchmaker named Degen, who raised himself in the air using mechanical means. Cayley believes that with the help of skilled artisans, the fundamental principles of aerial navigation can be brought into practical use. He argues that attaching wings to a man's arms is impractical, but if a man can exert his strength on a light surface, he can fly like a bird. Cayley proposes using a first mover, such as a steam engine or an engine powered by the expansion of air, to generate power for aerial navigation. He estimates the weight and power of such an engine and suggests that it could be used to convey people and goods through the air with greater security and velocity than by water. Cayley also analyzes the action of a bird's wing and proposes a design for an aerial vehicle based on this principle.
