Future astronauts were born in collective farm households and graduated from vocational school in early adolescence. Gagarin was moved from 1951 to 1957 in a six-year period at a molding plant to a garage, and three years later, a talented pilot was spotlighted at a committee on future astronaut selection. However, besides strict physical limitations (age, height, weight, psychological indicators), the party members were also considered. Incidentally, Gagarin luckily joined the CPSU rank in 1960.
