How people learned to fly?

The legendary Leonardo da Vinci a lot of time was devoted to the question of how to lift a person into the sky, so he opened the wings, hovered in the air like a bird. Lack of sleep nights and days, he sat and watched the birds.



Now we think little of that: took the money, bought a ticket and you're in the sky. Today, I fly everything, well almost everything. 650 million people on average carrying five of the largest airlines in the world. And this is approximately 9% of all the inhabitants of the earth. Of course the Da Vinci for his work never got the spear, then as one of the companies sells its air service at $ 40 billion annually. An old dream of genius today has become the largest business. It all started from the ancient legend of Daedalus and his son Icarus. We all remember that story when the son escaped his father burn their wings under the hot rays of the sun. But it's just a myth.

As for the facts, the story goes that people always wanted to fly. Because they don't have the resources, we learned to slowly lift into the sky different objects. In Ancient China, for example, doing a flying serpent, in the mouth of which was flammable, which contributed to his flying abilities. The same Leonardo Da Vinci, in the Renaissance made sketches of a glider, aeroplane and flying machine like a helicopter. But, in order to raise all of their inventions into the sky, he missed one very important part – of the motor.



History knows a lot of those who have invented various devices for the flight, but it was not so good. The real opportunity came in 1766, when the British Henry Cavendish invented the hydrogen. It is through open and made its first flight in a balloon in 1783. Then began the era of balloons. After people invented derogable, but he was very impractical and dependent on wind. The first prototypes of modern aircraft were designed in the early twentieth century. But all parameters of the structures was done intuitively. Therefore, all attempts to fly were failures.



Only in 1903 the Wright brothers examined all the aerodynamic capabilities of the wings, made the machine with the engine combustion, which flew 260 meters. 2 years later, their aircraft broke the 39 km. From the years, technology improved and now we have monsters that can travel thousands of miles with hundreds of passengers on Board.
