Transcript for Father Saves Son After Roller Coaster Seat Belt Breaks
Back now with a roller-coaster ride that took a terrifying turn in Texas after a 6-year-old's seat belt break, he slips down and his father captured the whole thing on his cell phone. ABC's Linzie Janis is here with the details. Good morning. Reporter: Good morning. This dad said he was filming his son's reaction to share with his wife. What he caught on camera was not what he expected. Watch as Delbert Latham and his son take a ride on the mousetrap. His dad filming it all. But on the first big drop, the 6-year-old mruvenging to the bottom of the car yelling, my seat belt. I got you, you're fine, I promise. Okay. Delbert quickly grabs caisson pulling him up then holds on tight for the rest of the ride. No more big hills. Okay, good. Reporter: Watch again as Cason disappears from view and then the look of pure terror on his face and when Delbert told a park employee about the broken seat belt. He said, I'm sorry about that. That's been happening sometime, that's when it made "More of you" angry obviously. Reporter: In a statement the park telling ABC news it promptly removed the back car from service and ensured all other seat belts were in proper working order. Rides at amusement parks like this are generally safe but accidents do happen. Three years ago Texas grandmother Rosa Esparza slipped out of her car at this six flags plunging 75 feet to her death. Her family suing the German maker of the ride and settling out of court. Amusement parks aren't federally regulated leaving it to individual states. Something some safety experts say isn't ideal. The consumer products safety commission that currently regulate portable rides no longer has jurisdiction over fixed site rides. We're at their mercy. Cow live in a good or a bad state for amusement ride safety. Reporter: As for that father and son whose video has now been viewed more than 150,000 times on Facebook, they say they're just glad the ordeal is over and have no plans to sue the park. Safety experts say parents should stick to reputable parks with strong safety records but watch the ride, watch how attentive the operators are and if something doesn't feel right trust your gut. Good advice. I can't believe he said it's been happening sometimes. Yeah. Apparently it was a secondary precaution. There was a lap bar but you saw the kid still slid through. When you're that little. Terrifying. Thanks, Linzie.
