I worked at a park where the looping coaster train had to do a last circuit of the track empty to park in the shed over night on the brake run. Attendants traditionally got strapped in and sent round as a bit of a treat. One time as we passed the operators cabin the operator was not in it. He was actually sat on top of the restraints i have never been so scared in my life, especially when he stood up on the helix and was almost decapitated.
