The first in the history of mankind flight into space on April 12, 1961. On the ship "Vostok" Yuri Gagarin made one revolution around the Earth, which lasted 108 minutes, and then landed safely near Saratov. The start was made from the cosmodrome "Baikonur". Flight height ranged from 175 to 302 kilometers. Flight preparation was in a hurry, so I had to abandon the emergency rescue system, additional brake setup and some other elements. After two days in Moscow held a solemn meeting with the participation of Gagarin, where he told the audience about his flight.
