The History of Airplanes
äžçŽ
The first successful airplane was invented by the Wright brothers in 1903. Before that, people had tried to fly, but their machines were not strong enough. The Wright brothersâ airplane was made of wood and fabric, and it had a small engine. Since then, airplanes have become faster and safer. Modern airplanes can carry hundreds of passengers and travel across the world in just a few hours. Air travel has changed the way people live and do business. However, airplanes also produce a lot of carbon dioxide, which contributes to climate change.
