Which 1903 event at Kill Devil Hills is widely credited as the first controlled, sustained powered airplane flight?

The 1903 event at Kill Devil Hills widely credited as the first controlled, sustained powered airplane flight was the Wright brothers' first flight.

Orville and Wilbur Wright achieved the flight on December 17, 1903, near Kill Devil Hills, North Carolina. Orville piloted the first attempt, which lasted 12 seconds and traveled 120 feet. The brothers made four flights that day, alternating as pilots; the final flight, piloted by Wilbur, covered 852 feet in 59 seconds.

The Wrights' achievement depended on more than an engine. They developed a three-axis control system using wing warping, a movable rudder, and an elevator. They tested ideas with gliders and built a small wind tunnel to compare wing shapes and improve lift calculations.

The claim to the first airplane flight has occasionally been disputed because other inventors made earlier powered or unmanned experiments. The Wright Flyer is widely credited because it combined sustained powered flight with onboard control by the pilot. The machine was damaged by strong winds after the fourth flight and never flew again.
