Computer glitch may be to blame for Six Flags coaster mishap
A roller coaster that stopped mid-ride over the weekend -- stranding passengers at the top -- remains grounded as state officials complete a safety inspection.
Superman: Ultimate Flight at Six Flags Discovery Kingdom in Vallejo suddenly stopped on Sunday, about 150 feet in the air. Park spokeswoman Nancy Chan said the ride will be closed while the park and the California Division of Occupational Safety and Health inspect the coaster.
Chan said officials used a crane to get to the top of the ride and then inspected the track and the cars.
"This was not mechanical whatsoever," she said.
One possible cause officials are considering is a problem with the computer system that runs the ride.
"It could be programming issues," Chan said. "I'll know more when we get the results of the testing."
Superman: Ultimate Flight was designed by engineers with Premier Rides, headquartered in Baltimore.
The park is open, but the ride will stay closed until the investigation is complete, possibly as early as midweek, Chan said.
"Safety is our No. 1 priority, and we will not open the ride if it isn't safe," she said.
