The Wright brothers did not create from the void, they copied lots of things from other innovators, specially Otto Liliental, whom they admired a lot. https://en.wikipedia.org/wiki/Otto_Lilienthal This is important because, for example they did not invent ailerons, but blended the wing and constant litigation from their patents block all progress in aviation in the US for a long time because they wanted to take possession of the inventions others have created(like ailerons) and became a monopoly. Only the war and the US gobertment intervening did stop the blocking. |

1. first mathematical propeller theory combining blade element theory with momentum theory, producing 90% efficient propellers
2. first lightweight aviation engine
3. first 3-axis control system
4. first use of wind tunnel to evaluate wing design of area, aspect ratio, airfoil section and tip shape
5. first research and development program using a series of prototypes to test each feature
6. correctly identifying that control was the primary problem
7. correctly identifying that an airplane must bank in order to turn
8. correctly identifying "adverse yaw" and the rudder as solution
