Leonardo da vinci conceptualized designs for flying machines in the late 15th century, particularly between 1485 and 1490. His sketches, including the famous "flying machine" resembling a modern helicopter and an ornithopter, demonstrated his keen interest in flight and his understanding of aerodynamics. While he never built a working airplane, his innovative ideas laid the groundwork for future aviation breakthroughs.
