英语翻译
One of the most important events in history happened on December 17,1903,at a place called Kitty Hawk in North Carolina,USA.It was the first flight of a powered aircraft.Only five people witnessed the event but,luckily,one of them took a photograph.People had flown for very short periods before,using wings of different kinds.In 1678 a Frenchman built a glider and flew it over a small building.About 200 years before that,Leonardo da Vinci designed a flying machine that was never built.The flight at Kitty Hawk was the first time an engine had been used to lift an aircraft up and power it through the air.The men who built his first powered aircraft were the Wright brothers - Orville and Wilbur.It was a biplane (which means it had double wings) with a small four-cylinder engine.The Wright brothers named it the Flyer.Orville was the pilot.He flew the plane for 12 seconds at about 30 miles an hour.This was the first flight of a heavier-than-air machine that took off into the air carrying a person,and moved forward to land at a point as high as that from which it had taken off.Where it landed was important because a plane can glide to a place lower than its starting point.From this date onwards things happened quickly,and in 1919 Alcock and Brown flew an airplane across the Atlantic Ocean,a journey of 1,889 miles.
