Orville and Wilbur Wright built their own wind tunnel to test airfoils and measure how to lift a flying machine into the sky. They were the first to discover that a long, narrow wing shape is ideal for flight. They figured out how to move the vehicle freely, not just across land but up and down on a cushion of air. They built a moveable part of the tail to control the pitch of their craft as it nosed up and down. They fashioned a pair of twin rudders in back to control its tendency to swerve off course. They devised a pulley system that warped the shape of the wings in midflight to turn the plane and to stop it from rolling side-to-side.

They used the data from their wind-tunnel experiments to design the first effective airplane propellers.

When they discovered that a lightweight gas-powered engine did not exist, they designed and built their own.
