Building on the work of gliding pioneers, the pair invented the three-axis control system—a standard in aircraft today—to control the plane’s flight at every stage, allowing pilots to direct movement from nose to tail (roll), wing to wing (pitch), and top to bottom (yaw). Their scientific, documented approach to aviation pioneered the use of wind tunnels, aluminum crankcases in engines, and more, laying the foundation for the industry.
Adoption and large-scale production of their airplanes took time, in part because many observers doubted their claims and the practicality of powered flight. In 1908, a series of public demonstration flights in the US and France finally convinced skeptics and brought the Wright brothers international fame, spurring a wave of competitors, imitators, and lawsuits.
