[00:01.56]In 1892, brothers Orville and Wilbur Wright [00:05.32]opened a bicycle-repair company. [00:07.68]The brothers were specialists in this area, [00:10.05]but they were more interested [00:11.26]in something else-aircraft. [00:13.79]The brothers used the company to support their [00:16.14]flying machine research and experiments. [00:19.26]There were many people trying to build [00:21.08]flying machines at the time. [00:23.08]The brothers studied them [00:24.37]and began their experiments in 1899. [00:27.64]On December 17, 1903, [00:30.52]Orville made the first flight [00:32.65]in their plane,the Flyer 1, [00:35.25]and he flew 39 metres in 12 seconds. [00:39.02]Wilbur piloted the plane later that day [00:41.76]and flew it 279 metres in 59 seconds. [00:46.60]During their research, [00:47.84]the Wright brothers always worked together. [00:50.58]They made great contributions [00:52.21]to the development of aircraft. [00:53.29]
