However, it seems that its inventors, Orville Wright and Wilbur Wright, were not looking to change the world at all. Rather, they just wanted to fly like birds. To solve the problem of heavier-than-air flight, the Wright brothers began working with gliders. There were two main challenges. The first was how to get the glider into the air. The second was how to control it once it was flying. For both problems, they found their solutions by looking at how birds flew. After they solved these problems, they added an engine to the glider. Then, in December 1903, the world's first plane flights were made. The invention of the plane has made our travels around the world much easier and faster. Journeys that once took days, weeks, or even months, can now be made in only a few hours. As a result, communication among people in different countries is now much easier, and the world has become a much smaller place. Paragraph 1 What was invented? Why was it invented?
