Bologna Guglielmo Marconi Airport and the Bologna Centrale railway station. Intamin has also constructed monorails at amusement parks Xi'an and Ningbo in China and the Asia Park Monorail in Da Nang in Vietnam. Notable Intamin rides Safety incidents Intamin has been in the news for a number of safety-related incidents. In 1984, three passengers riding The Edge at Six Flags Great America were injured and briefly hospitalized. The ride experienced a malfunction that caused it to fall backward down the wrong shaft. On June 9, 1991, 32-year-old Candy Taylor of Toledo, Ohio, fell to her death from Flight Commander, an Intamin Flight Trainer, located at Kings Island. Investigators determined that a design flaw in the seat divider could allow a rider to slide into an unoccupied seat and become free from the restraint. A coroner's report later revealed that the victim had a blood-alcohol level of 0.30 which may have also contributed. Speculation suggests the rider lost consciousness during the ride and slid out from the restraints. On May 16, 1999, a guest was unable to close his lap bar on Ride of Steel at Six Flags Darien Lake. As a result, he was ejected, fell approximately 9 feet as the ride went over a camel hump hill, and suffered serious injuries. He sued the park and the ride manufacturer for negligence and was awarded US$3.95 million. In August 1999, a 12-year-old mentally disabled boy fell from the 207-foot (63 m) high Drop Tower: Scream Zone, at California's Great America, and died. The victim's family claimed his harness was not locked properly. An investigation was inconclusive and no charges were filed. In September 2001, a 40-year-old woman fell from Perilous Plunge (Knott's Berry Farm) into the water, was hit by the boat, and died. An investigation showed that the woman had loosened the safety restraints, so she could fit more comfortably into the ride. On April 16, 2004, a 16-year-old girl from Pontypool was killed after falling approximately 30 m (100 ft) into shallow water from the top of Hydro (now called Drenched) at Oakwood Leisure Park, Narberth, Pembrokeshire, United Kingdom. During a lawsuit brought by the victim's family against Oakwood, a jury returned a narrative verdict stating that the victim had fallen out due to being improperly restrained. The second incident of 2004 was on one of Intamin's mega coasters, Superman: Ride of Steel, at Six Flags New England
