An investigative report into the death of a man on Superman - Ride of Steel at Six Flags New England theme park has stated that the ride operators, the ride manufacturer, and the victim were all at fault.
The Department of Public Safety identified the following contributing factors that resulted in the death of the rider.
1) The girth of the victim - due to his size the t-bar restraint could not be properly secured to prevent his ejection.
2) Pre-existing medical condition - the victim failed to notify the ride operators of his disability.
3) Varied seat belt sizes - the front seat of each car is fitted with a larger seat belt that allows larger patrons to ride, and thus not be properly secured.
4) Failure of the ride attendant - the ride operator failed to identify that the t-bar was not in the position necessary to prevent the ejection of the rider.
The report also states that both the seat belt and t-bar were locked when the train returned to the station. All three Superman - Ride of Steel roller coasters will remain closed until they are fitted with new approved restraints.
