Many years ago I worked for Disney to help fix the rides when they broke down. I am a certified electrician and mechanical engineer and worked at a few theme parks before that one. I am sure you have all been in lines when things broke before and as a guest, this can be very frustrating. It happens, especially during the summer months when the machinery gets really HOT. This causes major issues and the mechanics to fail. My job was to go in with a few members of my team and get the rides operational as quickly and safely as possible. We did multiple safety checks afterward even if we could hear the groans. I wouldn't let anyone on those rides till it was ok to do so. Safety should ALWAYS come first no matter what park you are visiting.
