In fact come to think of it hitting water straight down on a chute.
No undercarrage to take any energy away.
Flat wing and body onto a incompressable fluid it will be like hitting concrete.
All those bits of rope about which you can't cut even if your spine isn't shattered and you have gone from being 6ft tall down to 4 ft.
So more than likely I reckon you will be stuck inside the thing as well as having multiple bone issues through having a huge G forces applied which will proberly break your neck anyway.
Yep another huge risk reduction that one.
