That was some serious acceleration by the escape system. Looked like +100 mph (160 kph) in a fraction of a second. I wonder what the chances are of a human crew sustaining permanent injury, like with fighter jet ejection seats?<p>(Yes, it's better than the alternative!)
Despite the chipper commentary I see no indication stepping through the YouTube feed frame by frame that a retrothrust system engaged and softened impact.<p>If it did it was within 10s of ms it looks like...?
The abort engine burn apparently used up the solid fuel engine, so the capsule landing wasn't gentle either. Looked like it dug a substantial hole.
