Years later, in 1899, Orville and Wilbur Wright began the work that would lead to the first airplane. Now adults, the brothers owned a bicycle shop in their hometown of Dayton, Ohio. In their spare time, they researched the subject of flight and began testing different types of wings that could lift a craft into the air.
The Wright brothers divided flight into three problems: The aircraft needed wings that could lift it into the air. It needed an engine that could propel it. And finally, it needed a means of controlling it in flight.

The problem of control was a tough one. The solution came from pigeons. While watching pigeons flying, Wilbur and Orville Wright noticed that the birds kept adjusting the positions of their wings. When a bird wanted to turn, it lifted the front edge of one wing while tilting the edge of the other wing down. By reversing the process, the bird could turn the opposite way.
The brothers began working to make an aircraft wing that could twist and turn like a bird's. One day, after Wilbur took a bicycle inner tube out of a long cardboard box, he noticed that by twisting the ends of the box in opposite directions he could make the edges of the box twist like the pigeons' wings. If only the brothers could make a flexible wing that could operate like this, they just might solve the problem.
Wilbur and Orville immediately began designing a glider to test the idea. It had two parallel wings and would be flown like a kite. But to fly their glider, the brothers needed to find an open place with strong, steady winds. They wrote to the U.S. Weather Bureau and were sent a list of possible sites. One of these was Kitty Hawk, North Carolina--a virtually uninhabited beach on Carolina's Outer Banks.


Still, the Wrights' gliders failed to fly as well as the brothers had calculated they would. In the winter of 1901, the Wrights used a wind tunnel to study the problem. The tunnel was a wooden box equipped with a fan. When the fan was in operation, it blew air through the tunnel at a steady 27 miles per hour. The Wrights put models of airplane wings in the tunnel. By carefully measuring the performance of these models, they were able to build better wings for their glider.

Back in Dayton, the Wrights worked to build propellers and a lightweight engine that could propel their aircraft skyward. In the fall of 1903, they returned to Kitty Hawk, where they practiced flying on the latest model of their glider as they assembled their new engine-powered craft.

After about thirty-five feet the Flyer lifted off the ground. But after just 3 1/2 seconds, it smashed back to earth. It took two days to repair the damages. But on December 17, 1903, the Wrights were ready to try again.
Now it was Orville's turn to be the pilot. He set up a camera, focusing it at the point where the Flyer would lift off. Then he took the controls. With Wilbur running alongside it, the Flyer picked up speed, then rose into the air.
At that moment, one of the local men snapped the camera shutter, taking the photograph that would preserve the moment forever. The first flight lasted only twelve seconds, and covered only 120 feet. But the brothers flew the plane three more times that day. The last flight, with Wilbur piloting, covered 852 feet in 59 seconds, proving conclusively that sustained, controlled flight was possible. The Wright brothers had changed the world. The Age of Flight had begun.
