VALLEJO, Calif. – Officials at a Northern California theme park say they have ruled out mechanical problems for the stalling of a roller coaster carrying a dozen people about 150 feet above the ground.
The riders were stranded upright aboard the new Superman Ultimate Flight roller coaster at Six Flags Discovery Kingdom in Vallejo for less than 90 minutes Sunday afternoon before the roller coaster was restarted.
Park spokeswoman Nancy Chan said crews on Monday found no mechanical problems with the ride or track.
They are still investigating what caused the coaster to stall and plan to run its cars later in the day.
None of the stranded riders was injured.
