WRITING 2 CARLOS CALLEJERO CUCO

 Airplanes, informally called "aeroplanes" or "planes" , are by far one of the most important inventions of the last two centuries. Since its creation in 1903, this extremely complex vehicle has been improving until the aeroplanes that we have nowadays, which are able to do things that we could not imagine only one century ago. 

It is important to mention that the most relevant goal that an airplane must accomplish in order to be able to fly is to lift their own weight. ¿How is this possible? Airplanes are able to reach what I have just said because they have wings. When a plane flies, the enginee pushes the plane and trasmits speed, when the minimun speed is reached, the wings start to create the lift that the plane needs. Once that the plane is "flying", the pilot (located in the cockpit) controls it with different parts of the plane. The yaw is controlled with the rudder and the vertical stabilizer, the pitch is controlled with the elevator and the horizontal stabilizer and the roll is controlled with the alierons. Another important part is the fuselage, the main structure of the plain that hold things together.
