I have always loved going to schlitterbahn since I was little, because they have some really unique rides and play areas and always win best lazy rivers and not so lazy river contests. Correct me if I'm wrong but they pretty much invented the uphill water coaster. But it seems in this case that they answered the question; what if the old Action park had a billion dollar budget? One cannot build extreme things with out extreme mathematics and a good bit of engineers skepticism. Normal Accidents are generally unavoidable and are the result of Incredibly complex systems operating in unpredictable patterns. This doesn't seem like a Normal Accident because you can attribute this death to one obvious cause; Overloading the of raft. To all involved and the public, overloading of the raft had very obvious consequences and the lack of control to prevent the most obvious failure to ride safety is most likely going to result at the minimum of a guilty of negligence verdict.
