The Dream of Flight
On December 17, 1903, at Kitty Hawk, North Carolina, Orville and Wilbur Wright achieved the first powered, sustained, and controlled airplane flight. Their aircraft, the Wright Flyer, marked the beginning of the aviation age.
The brothers' success came after years of research, experimentation, and innovation. They approached the problem of flight with scientific rigor, solving challenges that had stumped others for centuries.
Scientific Breakthroughs
Wind Tunnel Testing
The Wrights built their own wind tunnel to test over 200 wing designs, collecting precise data on lift and drag that contradicted existing tables.
Three-Axis Control
They invented wing warping for roll control combined with a movable rudder and elevator, creating the first practical three-axis control system.
Lightweight Engine
With Charlie Taylor, they built a 12-horsepower, 180-pound aluminum engine when no existing engine met their power-to-weight requirements.
The Wright Flyer's Key Components
Materials Used
- Wings: Spruce wood framework covered with muslin fabric
- Engine: Aluminum crankcase (revolutionary for the time)
- Propellers: Hand-carved spruce, designed using their wind tunnel data

Development Timeline
1899
The Wright brothers begin serious aeronautical research after being inspired by Otto Lilienthal's glider experiments. They build their first kite with wing-warping controls.
1900-1902
Series of glider tests at Kitty Hawk. They discover flaws in existing lift data and build their own wind tunnel to conduct systematic tests on wing shapes.
1903
Construction of the Wright Flyer with a purpose-built engine and propellers. After several failed attempts, they achieve four controlled flights on December 17, with the longest lasting 59 seconds and covering 852 feet.
1904-1905
Development of the Wright Flyer II and III, making significant improvements in control and reliability, including the first circular flight in 1904.
