"the three #cosmonauts would have had a good chance of returning in the broken #Soyuz. Like me, Chris #Hadlield expressed his basic confidence in the Soyuz.
Pretty much all important functions can be triggered by the crew. For all points in time, e.g. for igniting the jets, a table is sent up daily, which is printed out and kept in the Soyuz. I can't say in detail whether the cruise engine overheats in the absence of cooling, but in simulations pretty much everything was played in for us and we still got as far as the upper atmosphere. From there on, the leaky cooling doesn't matter anyway. If there's a moisture problem in the capsule before the braking shock (that's where the cooling acts as a condensation surface) or it gets too hot, thanks to the Sokol #spacesuits you can deflate the air in the return capsule and come back under pure oxygen pressure. Very uncomfortable, but #doable. Soyuz is a life saver, not a limb saver, we were always told."
