The first successful airplane was created by the Wright Brothers, Wilbur and Orville. Airplanes are fixed-wing aircraft that use a 3-axis control and are propelled through the air using engines. Airplanes are commonly used for transportation, however, they are also used for research, recreation and military purposes. The engines located on the wings of the airplane create lift, overcome drag and allow the plane to travel forward.
Most airplanes place their country’s flag on the tail of the plane. As of 2014, there are more than 29,000 international and domestic flights taken daily on airplanes. The United States generates more than $170 billion in revenue annually from airplanes and the airline industry. The body of an airplane is called a fuselage and pilots control the plane from the cockpit located in the front. The wings of the airplane create a shape known as a airfoil, which creates lift and allows the plane to fly forward.
Some airplanes, generally military or research, are able to perform supersonic flight. This occurs when the airplane breaks the sound barrier and travels at speeds faster than sound. This speed is equivalent to 1235kph or 768mph. As of 2014, there have only been a few commercial aircraft capable of performing supersonic transport. The Concorde is one of the more recognized supersonic aircraft, and it flew between New York and Paris in three and a half hours.
