OKLAHOMA CITY (AP) — No one was injured when a roller coaster at an Oklahoma City amusement park stalled out and stranded eight people, including seven children.  See video here.

Oklahoma City Fire Department District Chief Benny Fulkerson says firefighters walked the stranded riders down a catwalk to safety Wednesday afternoon after the Frontier City ride became stuck.

The riders, which included children ages 7 to 15, were stranded on the coaster for about an hour Wednesday.

Fulkerson says the Silver Bullet roller coaster at Frontier City “just didn’t make it over a hill” and became stuck.

Fulkerson says power to the ride was shut off and the cars were chained to the rail before the stranded riders were escorted down one at a time.
