НУЖЕН ПЕРЕВОД ТЕКСТА НЕ ИЗ ПЕРЕВОДЧИКА,ПРОШУ
For many centuries people watched birds and dreamed that they could fly. We cannot fly like birds: we don`t have enough strength in our arms to move wings up and down. We also really need the power of an engine to drive up forward. Many people died learning these lessons, before controlled flight became possible.

The first flying machine which could carry a human being was built in Spain in 875. Reports tell us that the inventor flew some distance, but the landing was hard: the man hurt his back badly and was never able to fly again.

It was possible that the news of his flight reached England, carried there by men returning from war in the Middle East. Whether this is true or not, in 1010 a man called Oliver jumped off a church roof in Mulmesbury. This time we know the distance of his flight - 125 steps.

In the last years of the 15th century, the Italian Leonardo da Vinci studied the flight of birds and made a number of drawings of flying machines. His early machines tried to copy the movement of birds` wings, which he didn’t fully understand. But less than 10 years before his death in 1519, he drew a machine with wings that didn’t move. One of the machines was built and it did fly.

In 1536 in France, Denis Bolor returned to the idea of moving wings. He tried to fly using wings that were moved up and down. The idea didn’t` t work and he fell to his death.
