A power outage Sunday at Six Flags Great Adventure in New Jersey left some patrons briefly stuck on rides.
Officials say a faulty transformer was the cause of the outage and that all guests who were on rides were safely unloaded within 20 minutes. A spokeswoman said that all rides at the park are designed with computer systems that provide safe locations for rides to stop, and ride operators are trained to help guests safely disembark.
Power was restored to portions of the park a short time after, and following a safety check some rides resumed normal operations.
In August, the Nitro roller coaster at Great Adventure lost power partway up its 233-foot peak, forcing riders to walk down along the tracks to the ground.
