A dozen people got stuck on a rollercoaster 140 feet in the air for nearly four hours.
It happened on the "Hollywood Rip Ride Rockit" at Universal Studios in Orlando last night.
One woman went to the hospital with neck pain.
This isn’t the first time this has happened. In August one person was hurt when cars stopped on this same coaster.
Officials say the ride will stay closed until they figure out the problem.
