It was invented by Orville and Wilbur Wright, two brothers from the United States. The Wright brothers owned a bicycle shop and loved to build things. They were especially interested in flight. At the time, many people believed that human flight was impossible. But the Wright brothers did not give up. They studied birds and how they flew. They built gliders and tested them many times. The gliders sometimes crashed, but the brothers learned from their failures. Their biggest challenge was controlling the glider in the air. They solved this problem by developing a system that allowed the pilot to control the glider’s movements. They also added an engine to the glider. On December 17, 1903, they made the first successful flight in Kitty Hawk, North Carolina. The flight lasted only 12 seconds, but it changed the world forever. Today, airplanes are used for travel, trade, and communication. They have made the world smaller and brought people closer together. The Wright brothers’ invention shows that with hard work and determination, dreams can become reality. 1. Where were the Wright brothers from? A. They were from England. B.

They did not set out to change the world, but their invention did exactly that. They were simply two brothers who wanted to fly like birds. By studying birds and experimenting with gliders, they solved the problems of flight. On December 17, 1903, they made history with the first successful flight. Today, we enjoy the benefits of their invention every time we travel by plane. Their story teaches us that curiosity, patience, and hard work can lead to world-changing discoveries. 1.
