wrong. but thats okay. A body falls at the same rate regardless of weight, and few factors play into speed altering drag (clothing, height, body position). And in the giant wingsuit Jeb was flying (Apache by Tonysuits)his speed was fast. While he is only going down at 40-60 mph he is traveling forward at over 100. To impact a wall at this speed, even with just your toes, could throw someone around so violently that even if you survived the impact it would be unlikely that you could get stable enough to pull your pilotchute, or even find it at that point.
And usually when you hear about someone living when they fall out of a plane the news gets it wrong and the parachute just malfunctioned, but something was out to slow their descent.
