Good footage of Russian cosmonauts in training - could include Yuri Gagarin.
Unissued / unused footage - dates and locations may be unclear / unknown.
Russian cosmonauts in training - Russia / USSR.
Cosmonauts experiencing weightlessness in training. Various shots as cosmonaut is strapped into Gravity Simulator and allowed to spin at great speed, so experiencing Plus Gravity Pulls, (possibly Yuri Gagarin).
Another is strapped into a swinging device which doesn't seem to agree with him (looks like he is about to pass out). Then a man strapped into a vibrating seat (looks quite funny). Another is shut up in a pressure chamber while men and women in white coats turn up valves and dials. The cosmonaut's head falls back, the valves are turned down and a man goes into to pull him out of the chamber.
Final shot shows C/U of can of film with Russian lettering on the top. A hand comes into shot and lifts the lid off to reveal a roll of film inside.
