Leonardo da Vinci’s fascination with flight stemmed from his deep observation of nature, particularly birds, bats, and insects. He produced over 500 sketches and 35,000 words on flight, culminating in the Codex on the Flight of Birds (1505–1506), a pioneering work that explored aerodynamics, lift, center of gravity, and gliding—concepts centuries ahead of their time... Historical accounts suggest a test flight attempt in 1503 involving his apprentice Zoroastro da Peretola on Monte Ceceri, which ended in failure and injury. While no evidence confirms da Vinci ever built or flew a working machine, his visionary designs laid conceptual groundwork for future aviation. Modern tests of his parachute and aerial screw confirm their theoretical soundness, even if impractical in his era.
