Kamanin is disturbed by the decision. He recalls that in 1961 flight of the Vostok with two or three crew was discussed, with flights to occur in 1962-1963. But at that time Korolev cancelled the plans, saying the Soyuz would be used for such missions. Now Soyuz will not fly until 1965, and he has changed his tune. Furthermore, the modified Vostok is inherently risky, with no way to save the crew in case of a launch vehicle malfunction in the first 40 seconds of flight. Unlike Vostok, the three crew will not have individual ejection seats or parachutes to give them a chance of escape in the event of an abort. The crew will be subject to 10 to 25 G's during an abort. There is no assurance the environmental control system can be modified to handle three crew. It all seems very unsafe, and Kamanin believes the six consecutive successful Vostok flights have given Korolev's engineers a false sense of the safety of the Vostok system. Kamanin is perplexed. How does he plan to convert a single-place spacecraft to a three-place spacecraft in a few months? Korolev has no clear answers, but asks for the cosmonauts' support of the scheme. References: 376.
