In 1899, Orville and Wilbur Wright developed a bi-wing construction known as the Wright Glider, which was an early iteration of their glider designs. This pioneering work laid the foundation for their subsequent experiments in powered flight, as they sought to understand and refine the principles of aerodynamics. The bi-wing design would eventually influence their later successful powered aircraft, including the Wright Flyer.
