More than a dozen riders on a roller coaster had to be rescued off the ride Thursday when the ride stalled and left them stranded.

DOZENS STRANDED ON STALLED ROLLER COASTER IN OKLAHOMA

The Silver Bullet roller coaster at Frontier City theme park in Oklahoma City stalled near the top of the ride’s chair lift. Firefighters were called to remove each passenger, one by one. No one was injured during the incident.

“Guest safety is Frontier City’s top priority,” the park said in a statement. “As soon as each guest has been evacuated from the Silver Bullet, a thorough investigation into the reason the ride stalled will take place.”

That same coaster stalled in the exact same position in June 2016, calling on firefighters to save eight stranded people. “It’s like being shot from a cannon as you rocket through this high-speed steel looping coaster,” says the theme park website of the Silver Bullet coaster.
