The Wright brothers, Orville and Wilbur, were two American brothers, inventors, and aviation pioneers who were credited with inventing and building the world's first successful airplane and making the first controlled human flight, on December 17, 1903. From 1905 to 1907, the brothers developed their flying machine into the first practical fixed-wing aircraft. Namely they marked the beginning of a new era, the era of air transport. Since that time people began covering long distances in a short period of time.
Invention of the Airplane
The Wright brothers, Orville and Wilbur, were two American brothers, inventors, and aviation pioneers who were credited with inventing and building the world's first successful airplane and making the first controlled human flight, on December 17, 1903. From 1905 to 1907, the brothers developed their flying machine into the first practical fixed-wing aircraft. Namely they marked the beginning of a new era, the era of air transport. Since that time people began covering long distances in a short period of time.
An airplane (informally plane) is a powered fixed-wing aircraft that is moved forward by power from a jet engine or propeller. Airplanes come in a variety of sizes, shapes, and wing configurations. The broad spectrum of uses for airplanes includes recreation, transportation of goods, people, military, and research. Most airplanes are flown by a pilot on board the aircraft, but some are designed to be computer-controlled. The first exploitative jet aircraft was the German Heinkel, which was tested in 1939. In October 1947, the Bell X-1 was the first aircraft to exceed the speed of sound.
Nowadays planes have big importance in our life. They plays big commercial role in the economics. Plane is the fastest transport in the world. There are two base kinds of plains. Airliner (the plain that transports passengers) and aircraft missile (the plane that could bombs the enemy`s equipment). The are a lot of sorts of airliner nowadays, but the most popular among airline companies is Boeing-737. The aircraft, which is made from 1967 to the present day! Every 5 seconds in the world takes off and lands one of the aircraft of the Boeing 737. It is the most mass produced jet airliner in the history of passenger aircraft. But the largest passenger airplane is Airbus A380. This airplane at once could transport 853 passengers. For example Boeing 737 could transport only 135 ones.
In conclusion I want to say that the invention of airplane has grate historic importance. Because the first airplane was invented in 1903 and it is widely used nowadays.
