Airplanes, also known as aeroplanes or simply planes, are a modern form of transportation that have revolutionized the way we travel and connect with the rest of the world. These flying machines use the principles of aerodynamics to lift and propel themselves through the air, making it possible for us to reach even the most remote destinations in a matter of hours. History The concept of airplanes dates back to the 18th century, when inventors and scientists began experimenting with the idea of flying.
