"Instead of using fundamental mathematical and physics calculations to design and build the ride, the two men had “rushed forward relying almost entirely on crude trial-and-error methods.” And although they realized that their finished product “guaranteed that rafts would occasionally go airborne in a manner that could severely injure or kill the occupants,” they went ahead and opened the ride anyway."

Yep. All you have to do is look at the thing and apply some basic mechanical principles (like conservation of energy) to know that you're rolling the dice. Just a little less friction to dissipate energy on the way to the top of the second hill and -- whee! -- you're airborne.

The worst are the nets and semicircular loops to which the nets are attached [1]. To me it is obvious that if you go airborne on the second hill (that has these nets, too), you will drag the net with you – it might as well not even exist. All that remains to keep you inside is the metal loops. Well, you are now flying through a cheese grater.
