Who they are

Leonardo da Vinci studied bird anatomy, wings, air and wind while considering how humans might fly. His Codex on the Flight of Birds, compiled around 1505–1506, joins observation with mechanical speculation. It belongs here as an early effort to understand flight, centuries before successful powered aircraft.

The flight notebook provides historical context for the timeline’s later aviation milestones.
