A group of people got stuck on the Shock Wave rollercoaster at Six Flags over Texas Friday morning.
Andrew Cook shared photos on Twitter of himself stuck on the ride. Corey Crawford told FOX 4 he had been up there with his daughter and her friend since around 11 a.m.
Workers in orange vests and hard hats climbed up on the track to bring the riders water. They eventually helped escort everyone down a steep staircase alongside the track.
The Arlington Fire Department said Six Flags declined its offer to help. Workers were able to safety remove everyone from the ride by 11:40 a.m.
"The computer system detected an error. At that point our main priority was ensuring the safety of our guests and reassuring their comfort as unnerving as that process may have been," said Sharon Parker, a spokeswoman for the park.
Corey Crawford was at the park celebrating his son's 13th birthday when his daughter and her friend got stuck on the ride.
"When it started going up the track you heard a noise right when it started and I noticed the sound didn't sound normal," Crawford said. "I had heard ten or twelve cars go up there at that time and it stopped all of a sudden about thirty feet beyond that and stuck."
Earlier this year Shockwave was updated with The New Revolution virtual reality headsets. Riders can wear visors to get the experience of riding in a fighter plane.
The ride was tested for a few hours without passengers and reopened to park visitors on Friday afternoon.
