There is a maximum height to fly on the Soyuz Capsule. You must be under six feet tall to fit safely.
A passenger (or space tourist) sometimes flies in the third seat of the Soyuz. However, that person is required to complete primary Soyuz training, which takes nearly a year.
Docking and undocking manœuvres are usually automatic, but the crew is trained to perform them manually.
Seat-liner contours are custom-moulded for each crewmember. They provide maximum comfort during ascent and descent phases while reducing the risk of injury. Shock absorbers underneath each seat help soften the impact of landing.
