In 1899, Orville and Wilbur Wright developed a bi-wing construction they called the "Wright Glider." This early design was part of their experiments with flight, leading to the creation of a series of gliders that helped them refine their concepts of aerodynamics and control. The Wright brothers' work laid the foundation for their later success with powered flight in 1903.
