That sounds to me like it might not be totally destroyed, but they'd
really rather not risk it. It's coming down on a parafoil, so it'll
have some forward velocity. Perhaps they are concerned about it
smashing into a cliff or rock.


Have I missed something? I would have thought that the initial impact,
wherever it occur, wouldn't be a big problem. What might be a problem is if
it landed on a hillside. One would then expect the capsule to get wrapped up
in the parafoil and thence to commence bouncing down the terrain at ever
increasing, and changing, velocities. I've often wondered whether the
inflated bag landings were such a good idea. A body can build up a lot of
angular momentum in a short time on even a minor slope.
