Can we say everyone was extremely lucky that day? Yes we can!
You do know that theme parks charge people to experience such eventful happenings.
Wow, I can't even imagine such a day, but surely glad everyone was safe and okay. I can tell you a boat running in circles can easily chop up a person in no time. I actually seen that happen years ago on a local lake. I don't know if the person made it or not, but they did carry her out in a blaring ambulance when they finally got to her.
She was sitting on the bow of the boat with her legs hanging over the bow. The driver seen a wave coming from a passing boat and when he hit the wave he throttled back throwing her over board. When he seen her going, he hit the throttle again thinking he would get her before she went totally over and actually drove over her... Not pretty whatsoever! It happens so quickly...
