The last flight of Yuri Gagarin

The first man in space was a Russian cosmonaut. He made history in 1961 with just under 90 minutes in orbit, in which he circled the Earth once, and consolidated the Soviet Union’s post-Sputnik position as leader in the Space Race. But just seven years later, the popular hero was killed in a flying accident with an experimental plane, along with another pilot. The precise circumstances have remained a mystery even to the authorities…until now.
