Yes, rides stop but I think the OP's point was the amount of time stuck on the ride.
To be honest, I would freak out a bit because I could easily think of some "worst case scenarios" while I would be sitting there letting my imagination run wild as to the reason we were stopped so long (fire, crazy person running around, etc.).
How?We also got stuck on Kilimanjaro Safari
How?
One of the trucks ahead of us stalled out. We then had to sit there for 20 minutes until they could get it out of the way. Between the spot it was at and the animals, it apparently took a little while. It would have actually been pretty cool, but we were stuck in spot where there was nothing to look at. Even our driver was about to lose it from boredom.
I just can't believe they left people on HM for over an hour. It isn't a water ride. It is very easy to walk out of except for a couple of tricky spots on the hills. They should have turned on the lights and evacuated. We've been walked off of more than one ride over the years.
Makes you wonder why they didn't just evac everyone after about 15 minutes. I would panic if I was in one of the cars tilted backwards.
I would def freak if I got stuck on tot for an hour!!!
