Why were early personal flying machines considered creations of aspiration rather than feasibility?
Answer
They required more energy to operate than they actually saved.
These inventions were conceived long before the fundamental principles of aerodynamics were fully understood. Because the inventors focused on the dream of flight rather than the practical mechanics of physics, they created machines that were fundamentally inefficient, failing to provide the mobility they promised due to a lack of engineering realism.
