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. https://web.archive.org/web/20180102002811/http://forums.hipinion.com/viewtopic.php?f=1&t=85204 https://web.archive.org/web/20180102002811/http://forums.hip... 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).
