Planes have changed the world in the last hundred years. But this great change began with two ordinary people.

Orville and Wilbur Wright were two brothers who had a bicycle shop in Ohio, the USA. They were good at making bicycles, but planes were their real interest.

At that time, people knew how to build and fly gliders (planes without engines), but nobody could build a plane with an engine and fly it. The plane builders had two main problems: they could not make the wings strong enough, and the planes always crashed(坠毁) when they tried to take off.

The Wright brothers read about these problems in a newspaper, and they decided to look for answers. They made small model planes in the bicycle shop and they built a wind tunnel to test the models. They also built real gliders. Finally, they built a plane with an engine, which they called The Flyer.

On December 17th 1903, Orville and Wilbur pulled The Flyer onto a fat sandy beach. The plane weighed 275 kilograms and had a petrol engine. The day was very cold, and there was a wind of about 30 kilometres per hour. The brothers tossed(投掷) a coin to see who should fly first. Orville won. He climbed onto the plane and started the engine.

The Flyer began to move into the wind, Wilbur ran along beside the plane, And then the plane took off：It flew for only 12 seconds, but someone took a photograph, and the plane flew into the history books.
