But once you build this machine and start shoving millions of people through it, you're bound to catch some of those rare people, and they will have cardiac episodes that are scary at a minimum, and are at the worst *fatal*.
For me, the lesson isn't that Disney did something wrong by building a giant cocktail shaker for human bodies. I'm not a thrill-ride guy, but lots of people like 'em and the machines themselves are benign for nearly everyone who puts their bodies into them.
