What major technological innovation did the Wright Brothers implement in aircraft design?

The adjustable wing warping system was a significant technological innovation implemented by the Wright Brothers in their aircraft design. This mechanism allowed the wings of their aircraft to change shape in flight, which helped control the aircraft's roll and improve its stability and maneuverability.

Before the Wright brothers, many attempts at flight did not incorporate such a flexible approach to wing design, leading to difficulties in managing flight control. By integrating wing warping, they effectively solved one of aviation’s core challenges: maintaining stable and controlled flight. This innovative feature was a crucial aspect of their success, allowing them to achieve sustained controlled flight for the first time in history.

Other options, while important in the evolution of aircraft design, do not capture this particular groundbreaking development that set the Wright brothers apart from their contemporaries.
