LAKE BUENA VISTA, Florida — A 12-year-old boy died after riding a roller coaster Thursday at the Disney MGM theme park, the Orange County sheriff's office said.

 

The theme park said a preliminary investigation showed the Rock 'n' Roller Coaster was operating normally, but it closed the ride pending the full findings.

 

The boy died after he was brought by ambulance to a hospital at about 11:30 a.m., a Disney statement said. But it was unclear what caused his death.

 

"We don't know if it is a trauma or medical call," sheriff's spokesman Jim Solomons said.

 

The sheriff's office is investigating at the scene. State park safety officials were also notified.

 

A Disney Web site description of the ride says: "Zoom from 0-60 mph with the force of a supersonic F-14, take in high-speed loops and turns synchronized to a specially recorded Aerosmith soundtrack."

 

Two other people have died after going on another Disney ride: Epcot's "Mission: Space." The space simulator spins riders in a centrifuge that subjects them to twice the normal force of gravity.

 

Daudi Bamuwamye, 4, of Pennsylvania, died June 13, 2005. An autopsy determined he died of an irregular heartbeat linked to an abnormal thickening of the heart muscle that can cause sudden death.

 

In April, a 49-year-old woman from Germany became ill and died after the ride. A medical examiner's report said she died from bleeding of the brain and had severe, long-standing high blood pressure.

 

The ride has signs warning people with heart, back and neck problems not to ride. Epcot now offers a tamer version of the ride that does not include centrifugal force.

Sad but at the end of the day people with health conditions should not go on those sort of rides

i agree.
