Wright Flyer III, Aviation pioneer aircraft at Carillon Historical Park, Dayton, US.

Wright Flyer III is a historic airplane preserved inside the aviation center at Carillon Historical Park in Dayton, Ohio, and recognized as the first practical powered aircraft capable of full pilot control. The machine features a wooden frame built from spruce, fabric-covered wings arranged in a biplane layout, and twin pusher propellers driven by a four-cylinder engine mounted behind the pilot position.

The Wright brothers built this airplane in 1905 after years of experimenting with earlier versions, improving the engine and control system to achieve reliable flight. Wilbur Wright flew it that October for more than half an hour in a single flight, marking the moment powered aviation became a practical reality rather than a brief experiment.

The name simply numbers the brothers' third powered machine, built in the winter of 1904–05. Its 1905 flights over Huffman Prairie were watched by few witnesses, since the Wrights guarded their patents; they themselves took over 300 photographs of the early motor flights. The restored craft is shown at the Wright Brothers Aviation Center in Carillon Historical Park, Dayton.

The Flyer III is displayed indoors in the Wright Brothers Aviation Center at Carillon Historical Park, part of the Dayton Aviation Heritage National Historical Park. The restored airframe keeps an estimated 60 to 85% of its original material, so look for the spruce struts, bracing wires and the slanted placard in front of the machine. The 1905 engine sits on the lower wing beside a mannequin in a brown jacket and goggles, posed prone as the pilot flew.

This airplane holds the only designation as a National Historic Landmark among all aircraft in the country. The recognition came because it proved for the first time that people could travel through the air for extended distances without needing to land immediately after takeoff.
