ARLINGTON (CBSDFW.COM) – There were some tense moments in Arlington late this morning for some people who started their July 4th holiday weekend at Six Flags Over Texas.

Several riders got stuck while riding the Shock Wave roller coaster. Some two-dozen people, including children, sat motionless in the hot Texas sun when the cars got stuck at about a 45-degree angle.

Officials with the amusement park said the ride came to a halt when the roller coaster computer detected an “error” and automatically stopped the car halfway up the initial incline.

After about half an hour, Six Flags workers helped all off the riders walk down a coaster stairway to the ground.

“There were multiple team members that were there, including some our maintenance engineers, who safely attached themselves to the ride so that they could free up the walkway area and assist our guests in getting down,” explained Six Flags spokeswoman Sharon Parker. “Our team members are very well trained on how to handle situations like this and they handled it as quickly as they could. The most important thing is that all of our guests were able to safely disembark.”

The Shock Wave roller coaster was closed and there’s word on when it will reopen. “Our next priority is to do a close inspection of why the computer system detected an error and wanted to stop the ride,” Parker said.

No one was injured in the incident and the park is open.
