Airplanes
History of the Airplane
The Wright brothers flew the first airplane in 1903. By 1905 the Wright Brothers had built a plane that was fully controllable and could fly stably for periods of time.
By World War I the airplane was a weapon. But the airplane continued to develop better technology.
Airplanes where in all the major battles of World War II.
The first jet craft was built in 1939, the Boeing 707, it has been flying for almost 50 years. From 1952 to 2013.
How Do Airplanes Fly?
An airplane is propelled forward by thrust from a engine. The plane stays in the air because the wings are supported by the air flowing around its wings. The wings of an average airplane are curved up, that creates lift. Without lift the wouldn't be able to get off the ground. To control the plane the pilot moves flaps on the wings and on the tail.
Benefits of the Airplane
Airplanes made traveling long distances quicker and more comfortable. The airplane took many years to develop into the grand passenger jets that they are today. They also took sending goods and packages to the next level. Now you can send a package all the way across the world.
