In reply to stone elworthy:
Sometimes you get lucky, sometimes you don't. Pads and landing skills can sway the luck one way or another, and some people just happen to be at bit bouncy.
Generally I'd be happy dropping off with my hands at 4m onto a single pad. Maybe a touch more if it's soft dirt beneath the pad. Maybe less if it's a bit sloping or uneven, and that's before you consider the nature of the move and the fall it may cause! That said, I've fallen from higher and put my foot straight to the floor through a gap and been fine, but some others have fallen not very far and hurt themselves quite badly. There's a great video of someone on Too Big To Flail in Bishop, he took an ~8m lob onto a load of stacked pads and was fine. And someone doing a backflip off Saigon!
Edit: I had a play on The Captain years ago, how on earth did that happen? I appreciate it's not the widest platform but generating that sort of momentum is impressive!
