They have myriads of info at there disposal and I think they probably will never have a death in their program.
That is true, but then again so do we. With about 140 manned space launches-we still have accidents and lose people. I don't think they have much of a better situation just because of the risk involved in any manned space flight. If anything, the only safety advantage they have is a newer capsule-but then again it's based on an old Russian's design. In the end, I think we are all about equil. Nither the US, Russia, or China will ever be able to make spaceflight completely safe and there will be accidents. Sadly, it is likely they will lose someone just because of that-eventually.
