Sounds like Ruin is looking for the sky to be falling. Yes, something/anything COULD go wrong. Will it? Probably not.
If you're not up for managed risk, you don't have to leave the
ground. Not even for dinner. Me, I'd jump on it in a heartbeat!
Not looking for the sky to fall, but up to looking for discussion of the possibilities, thus the title of the thread. You are a trained professional, these are average joes (clients) who may not take the risk seriously. Why do you think that on amusement
park rides they make it so the user is unable to remove their
safety devices by themselves (most of the time anyhow)? My guess is to prevent people from earning a Darwin award.
Sure, I saw that this is something that is done worldwide. That doesn't mean it's a good idea. Remember the early years of bungee jumping? A lot of professionally designed systems resulted in quite a few tragedies. Maybe statistically speaking it (bungee jumping) has always been safe, but tell that to the families of the maimed and deceased. So, managed risk, sure. I doubt we'll see any tragedies, at least not in the near future.
Judging by the cranes in the photos, I doubt any of them will collapse (unlike the umpteen construction crane collapses I previoulsy mentioned) judging by the observed load. That doesn't say that it can't happen.
And lastly, my comment about the adult diapers wasn't due to anyone being at risk and having the piss scared out of them. I was thinking logistically, how do they manage people having to use the facilities? Do they have to take the whole party up and down each time someone has to go? That seems like a real pain.
Hope that clears things up.
