    [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]
