Would highly encourage some of the more recent posters to go back and read the full report I linked to.
I'm not saying the park is cleared of all responsibility but the report makes it extremely clear that nearly all the fault lies within the operators. Contributing parties include BOTH the park and the manufacturer more or less due to improper documentation.
If the first opetator had done their job correctly like they were told to by the park, this would have not happened, period. So get a grip and read the report then come back and we can have a discussion, I'm all for it.
