I pointed this out earlier, but Space Mountain is much less intense and five people have died on it. Has nothing to do with the design as many, many people have safely experienced that ride. Well, aside from some chiropractic adjustments.

There have also been instances on FOP of guests losing consciousness; this is a ride I myself don't do. Fortunately, the way you are seated, your head wouldn't bang around, and they can easily stop it if they see you've passed out. I can see that this would have been an issue where a guest lost consciousness and then his head got banged around because he couldn't properly hold on during a rollercoaster.
I mean, if we're questioning things, people have drowned in pools. Should we take them out? Or just take safety precautions?
That's why I have said a reasonable precaution would be more visual monitoring so that if they see a passed out guest, they can do an e-stop and assess, as well as having more training for staff members. It's reasonable in any environment where there's a lot of guests, as was illustrated by the guests who passed on HM at DL and Frozen at HKDL recently.
