A wheel on one of the ride’s cars separated from the track, causing the ride to stop suddenly. The most seriously injured in the accident was a German woman, who was taken to the hospital for multiple bruises. It could have been worse, however, as Disney spokesman Ray Gomez told the Los Angeles Times at the time, “All normal ride safety control systems worked as designed and brought the system to a halt.” Estimated U.S. incidents, 2009: 57 Notable incident: Near the end of the summer season in 2003, a malfunction at Disneyland’s Big Thunder Mountain Railroad killed one man and injured 10 others.

He was killed on impact. Disney CEO Michael Eisner appeared at the park the next day to reassure park-goers, saying, “We are working very closely with local and state authorities to gather the facts and determine the cause of this accident as early as possible.” Estimated U.S. incidents, 2009: 60 Notable incident: At Texas’ Six Flags park in 1999, one woman was killed and another 10 were injured when their raft flipped over on the Roaring Rapids water ride.

In 2002, Lori Mason-Larez, 40, was seated next to her children and nieces on the ride when she flew out and fell to her death. Passengers on the ride tumble down a 115-foot, 75-degree drop at nearly 50 mph. Investigators pointed to Mason-Larez’s size as a contributing factor, as she weighed 292 pounds, as well as an inadequate restraint system. “We think they need to go over everything one more time," said Len Welsh, California’s special counsel for regulatory development, at the time. "We're not convinced this is just an issue for a person larger than the average human being.” Estimated U.S. incidents, 2009: 72 Notable incident: Three-year-old Nadia Laberge was riding a vintage-style car ride in 2001 at La Ronde amusement park in Montreal.

Estimated U.S. incidents, 2009: 84 Notable incident: Last summer, a British teen was looking for his goggles at the bottom of one of the pools in a Thai water park when he became trapped in the pumping system after removing a grate. His father dove into the water to try to save him but could not find any trace of his son, Nathan Clark. Reportedly, staff at the park was reluctant to help because they didn’t believe it would be possible for a person to remove the grille. Engineers recovered the 14-year-old’s body in the pipe connected to the pool’s pump room. Estimated U.S. incidents, 2009: 87 Notable incident: In 2005, a teen riding the Timber Wolf wooden roller coaster at Kansas City’s Worlds of Fun was killed from a fall after being ejected from her seat. Ashley Fenzel, the 14-year-old who was sharing the seat with Ryan Bielby, claimed that the seat belt and lap bar came loose as the ride went over a hill, ejecting Bielby into the air. Subsequent tests using crash test dummies caused experts to doubt that restraint malfunction caused the accident. “The tragedy could not have occurred as has been reported by the remaining passengers in that car," John Hudacek, general manager of the amusement park, told reporters at a news conference.
