Typhoon Seacoaster at SFA nothing is as bad at it it usualy runs 5-9 out of a total of 18 boats (Intamins Worst Ride). Then it's tunnels are just falling appart theming. Cool ride the first time takes to long. Average of 5min because of faults.
During a malfunction on Batwings locking lights 2 years ago myself and 3 other attendants tested it we were only supposed to test the seats in station but the maintenece guy was funny and dispatched.
