What contribution did the Wright brothers make to mankind? What did you learn from them? Tell me about the inspiration of the Wright brothers before they invented the plane.

The story of inventing the airplane.

1in the winter of 877, there was a heavy snow in Dayton, USA, and the hills in the suburbs were all white. A group of children came to the hillside covered with thick snow and slid down quickly in a homemade sleigh. Laughter broke out on the hillside.

Next to them, two boys stood quietly, watching the cheerful sledge pass from top to bottom. The big boy sighed, "Hi! If only we had sledges, too! "

Another child pursed his lips and said, "Who told us that dad was always away!" " "He had a brainwave and then said," Brother, let's do it ourselves! " Hearing this, the boy called brother immediately laughed and said happily:

"Yes! We can do it ourselves. Come on, Orville, let's go back! " So, the two children jumped off the hillside and ran home quickly.

The two brothers are the Wright brothers, the elder brother is Welber and the younger brother is Orville. They like to play some things since childhood and often play all kinds of games together. Their grandfather is a craftsman who makes wheels. There are all kinds of tools in the house. The two brothers regard this place as their paradise and often go to see his grandfather's work. After a long time, they imitated and made some small toys. So, the two brothers decided to build a sledge this time and pull it to the hillside to compete with their companions. That night, the two brothers told their mother the idea. Hearing this, my mother said happily, "OK, let's do it together!" " "

So, the two brothers ran to grandpa's workshop, found a lot of sticks and tools, and did it without thinking.

"No," their mother stopped them from saying. "We must do everything in a planned way. We have to draw a picture first and then do it! "

The two brothers understand this truth and design patterns with their mother. Mother measured the bodies of the two brothers first, and then drew a short sledge. "Mom, someone else's sleigh is very high. Why is your sleigh so short? Will this work? " Orville, the younger brother, asked.

"Son, if you want the sledge to run fast, you have to shorten it, which will reduce the wind resistance and make it much faster." Mom explained gently. The two brothers realized that nothing should be done rashly, and they should first find out the truth.

A day later, the Wright brothers' short sleigh was made. The two brothers pushed it to the mountain, and just after putting it on the hillside, a boy came running.
