Yes, there are rockets that fire about .2 seconds before landing, plus the seats automatically activate cushioning springs just before touchdoiwn. You still get a jolt, but it’s nowhere near as bad as it looks.
Two things I noticed was that there was a tarp on the ground where their chairs were placed and they wore sunglasses. I wonder what the purpose of the two were. Peggy must feel a lot heavier than she really is. 288 days in zero g must feel weird after you land. Valery Polyakov was out walking track two days after he came back from 400 some odd days in weightlessness. Said he felt great.
Their seats also moves forward and assumes an angle that helps withstand the shock of landing. But, as you said, ain’t no biggie.
