Alexei Leonov, the first human to walk in space, has died
Given the state of Soviet engineering at that time along with the pressure to get a spacewalk before the Americans, I can't help but believe that the probability that Leonov would not come home must have been huge and yet, he did his job. As an American, I have tremendous respect for our astronauts in that era but that respect is certainly earned by the Soviet men and women who went into space.
