For many times, they risked their lives to test their airplane. Finally, after lots of calculations and improvements, they succeeded. 3. The invention led to a quantum leap in human history. From then on, better and safer airplanes have been invented and long flights have become increasingly convenient and comfortable. Their aroundtheworld trips have become a reality.

The Wright brothers have also inspired generations of people to make great achievements in their own fields. China, for example, had to depend on the Western countries for their large airplanes. Of course, our country didn't want to continue that way forever. With the same adventurous spirit as that of the Wright brothers, Chinese people kept trying and made great progress. Today, China has its own large airplanes.4. Thanks to the Wright brothers, humans realized the dream of flying. Till today, their experiences still have a great influence on young people.5.
