Re: 9 G's...
It's not clear whether it's a technical error or a human one, but they were submitted to 9 G's and after landing, had to open themselves the hatch.
All this after spending 161 days in space.
I don't think a long duration crew ever had to open a hatch or even endure that many G's after such a long time in weightlessness.
OTOH, it shows how the capsule can allow for their safe return, even if it's unconfortable.
No need to aim precisely at a landing strip.
