Otto Lilienthal, a German engineer, began his aeronautical research by studying bird flight in 1871. After nearly two decades of trial and inquisition, he produced the best and most complete body of aerodynamic data up to that time. He published his results in Der Vogelflug als Grundlage der Fliegekunst (Birdflight as the Basis of Aviation) in 1889.
On October 2, 1902, the Wrights' glider was the worlds first fully controlled aircraft. This glider had a three- axel control system, after modifications to their previous model. This control system was their single most important design breakthrough, and was the central aspect of the flying machine invention they later obtained.
1903 marks the year the Wright brothers invented the first
