The Wright brothers were able to control the flight of their manned aircraft through the use of wing warping. Far more sophisticated than Lilienthal’s use of shifting body weight, wing warping allowed aerodynamic control of the wing.
The Wright brothers were meticulous in their research. This research, along with their can-do and innovative approach to flight, resulted in their first successful, controlled, heavier than air flight at Kitty Hawk.
