He was a Soviet cosmonaut and the first man known to have died during a space mission. He was commander Pilot of Voskhod I, on a day-long mission, in 1964. Also, there was dr. Yegorov, a medical doctor as flight physiologist and the spacecraft engineer Konstantin Feoktistov. During landing, the spacecraft’s parachutes opened at an altitude of 7 km followed by a soft landing system that used streams of gases from nozzles to reduce touchdown velocity to near zero. He died during his second mission when his spacecraft became entangled in its main parachute and fell several miles to Earth.
