Interesting double autobiography of Soviet cosmonaut Alexei Leonov and American astronaut David Scott - memories and a documentary story about like the "lunar rivalry" between the USSR and the USA, which grew into the Soyuz-Apollo space project, marked the beginning of the era of scientific and technical partnership between the USSR and the USA. Scott and Leonov, as leading participants in that unprecedented race of space achievements, greatly respected each other and, in fact, more than anyone, they realized all the problems, the severity of the tests and the degree of risk that threatened the opponent. These biographies, told from the perspective of two very different cultures and societies, are united by the desire of real researchers to participate in the most advanced space events and respect for the technical achievements of the opposite side.
