VALLEJO (CBS SF) — The Superman Ultimate Flight roller coaster at Six Flags Discovery Kingdom left passengers stuck, after reopening one week after it stalled mid-ride and stranded a dozen riders, a spokeswoman for the park said Sunday.
The roller coaster was cleared by safety inspectors and began regular operations earlier Sunday, Six Flags spokeswoman Nancy Chan said.
Shortly after reopening, the ride suffered a glitch, leaving passengers stuck. Park officials were able to quickly remove those passengers from the ride.
The park blamed the problem on a computer glitch.
Cal-OSHA was continuing to investigate why the ride also stopped about 3 p.m. on July 29.
The Vallejo Fire Department responded to that incident, and two members were raised 150 feet on a mobile platform to reach the roller coaster. The coaster was un-jammed and rolled backward to its starting point.
No one was injured, though riders were stranded for about two hours.
Cal-OSHA had no deadline to finish its investigation into the incident.
