OKLAHOMA CITY – It was a terrifying trip to an amusement park for some thrill seekers.
On Wednesday afternoon, the Silver Bullet at Frontier City stalled about 100 feet from the ground.
Employees at the amusement park were able to evacuate riders from the back cars, but several riders in the first cars were trapped.
In all, eight passengers had to wait to be rescued by firefighters from the Oklahoma City Fire Department.
The Oklahoma Department of Labor shut down the ride to investigate what happened and why the coaster stalled on the tracks.
Now, officials are releasing details from that investigation.
The Oklahoma Department of Labor says the Silver Bullet suffered a “momentary power drop that caused a sensor fault.”
At that point, the roller coaster’s safety measures kicked in.
“The coaster’s computer program is designed to shut down the lift if a sensor on the track is triggered,” the report reads.
Investigators say that after the riders were brought back down to the ground, crews were able to reset the ride.
“The Department of Labor inspector returned to Frontier City to conduct a reinspection of the ride. Department of Labor conducted the reinspection on the Silver Bullet and found all safety aspects of the ride meet the manufacturer’s standards,” the report states.
