in Massachusetts. The ride, again with lap bar restraints, was dispatched with a rider who had cerebral palsy in the front seat; this passenger subsequently died after being ejected from his seat. According to an investigation, the ride operators were primarily to blame, for not ensuring the rider was properly secured. Intamin was also partially blamed, as the ride's safety system allowed the train to be dispatched without all of the restraints properly secured. The third incident of 2004 happened on July 14 and involved one of Intamin's launched stratacoasters. Four people were injured while riding on Cedar Point's Top Thrill Dragster. The riders were struck by metal debris that sheared off from the coaster's launch cable; during the initial launch, the train accelerates from 0 to 100+ miles per hour in a matter of seconds, before climbing up the 400+ foot vertical structure and back down again. The majority of guests waiting in the queue line would be standing no more than 10 to 15 feet from the track, at closest range. They were treated at the park's first aid station. Two were further treated at Firelands Regional Medical Center. In June 2007, a 13-year-old girl shockingly lost both feet at the ankles on Superman: Tower of Power, at Six Flags Kentucky Kingdom, when a ride malfunction caused a cable to snap. She was brought to the hospital in critical condition, but miraculously survived, with doctors being able to re-attach her right foot. The park was later fined a mere $1,000 for not properly maintaining the ride; An undisclosed settlement was later reached with Six Flags, which will provide for her for the remainder of her life. On September 16, 2009, two guests were injured when a cable snapped on Xcelerator at Knott's Berry Farm. This ride is a smaller version of Top Thrill Dragster at Cedar Point in Ohio, or Kingda Ka at Six Flags Great Adventure in New Jersey. The train launches riders from 0 to 80 miles per hour in a matter of seconds, ascends a vertical top-hat, and descends down the other side. The 12-year-old victim had lacerations on his leg, while the adult victim complained of back injuries. On April 29, 2010, a ride train on Expedition GeForce partially derailed from the track, fully occupied with passengers. Riders were stranded 20m in the air, with eight of them complaining of nausea and bruising. On
