Similarly I had just read this thread summary about a person asking how to fix a zipline that had been built without any engineer input. They'd only calculated after spending $40,000 and building two massive platforms that it would probably kill anyone who rode it.

The OP article took a different turn when I got to the part where it said a government-approved engineer checks his rides (what the people in the thread I linked definitely didn't do).

There is an interesting audiobook about the place by the founders son (who worked there). It’s obviously biased, but does not turn a blind eye to all of the issues, I found it pretty interesting and certainly a fascinating story:
