Well, there are "no less than 13 warning signs addressing pregnancy, height minimums, motion sickness, high blood pressure, heart, back or neck problems, and a recommendation that you be in good health" -- isn't that enough of a clue to parents that this isn't It's a Small World?

It doesn't seem evident to me (at least not yet) that age, specifically, had much to do with this tragedy, except with regard to how much emotion the tragedy has evoked.
