On January 16, 1969 cosmonauts Boris Volynov (call name “Baikal-1”) and Vladimir Shatalov (call name “Amur-1”) docked two spacecrafts “Soyuz-5” and “Soyuz-4”.
Two cosmonauts, Yevgeny Khrunov and Aleksey Yeliseyev, exited to the open space and moved from the spacecraft “Soyuz-5”, piloted by cosmonaut Boris Volynov, to the spacecraft “Soyuz-4”, piloted by the commander, cosmonaut Vladimir Shatalov.
The “Soyuz-4” and “Soyuz-5” ships were docked for 4 hours and 35 minutes.
For the first time, manual approach and docking of spaceships were carried out, thus, for the first time in the world, an experimental space station was created, the transition through the open space of cosmonauts was carried out.
