1969-004A
7K-OK (11F615) No. 12 was launched on 1969 Jan 14 with pilot Vladimir Shatalov aboard.
After docking, Soyuz-5 bortinzhener (flight engineer) Aleksey Yeliseev and inzhener-ispitatel' (test engineer) Yevgeniy Khrunov transferred from the BO of Soyuz-5 to that of Soyuz-4. The Yastreb spacesuits had life support systems strapped to the legs, to allow the astronauts to fit through the 0.66m diameter BO hatches (later missions had enlarged hatches).
Khrunov went outside first, then returned to the compartment because he had connected Yeliseyev's suit to external supply instead of his own. After he transferred and connected to Soyuz-5, Yeliseyev made the transfer. The Yastreb spacesuits were left in the Soyuz-5 orbital module.
