The space vehicle is shoddily constructed, running dangerously low on fuel; its parachutes — though no one knows this — won’t work and the cosmonaut, Vladimir Komarov, is about to, literally, crash full speed into Earth, his body turning molten on impact. As he heads to his doom, U.S. listening posts in Turkey hear him crying in rage, cursing the people who had put him inside a botched spaceship. . . .
In 1967, both men [Komarov and Gagarin] were assigned to the same Earth-orbiting mission, and both knew the space capsule was not safe to fly. Komarov told friends he knew he would probably die. But he wouldn’t back out because he didn’t want Gagarin to die. Gagarin would have been his replacement.
