1485 Leonardo da Vinci - The Ornithopter and the Study of Flight.
Leonardo da Vinci made the first real studies of flight in the 1480's. He had over 100 drawings that illustrated his theories on bird and mechanical flight. The drawings illustrated the wings and tails of birds, ideas for man carrying machines, and devices for the testing of wings.
The Ornithopter flying machine was never actually created. It was a design that Leonardo da Vinci created to show how man could fly. The modern day helicopter is based on this concept. Leonardo da Vinci's notebooks on flight were reexamined in the 19th century by aviation pioneers.
