The most important inventions of mankind

People in space.Once the aircraft in the above be campanological, left us with only an age-old dream of humanity - a flight into space. As the first made the Union of Soviet Socialist Republics, and the first man in space was Yuri Gagarin. However, on the Moon as the first expedition reached the United States.
