Now we turn to that scare at a theme park in florida. 12 passengers on a huge roller costar trapped in midair for more than two terrifying hours. We have news tonight on what went wrong and here is matt gutman. Reporter: Think upwards on this rollers coaster and it seems you're threading a needle. Right there as you're plunging to the other side, you stop. That's what happened to 12 passengers, 3 of them children wednesday night. Leaving them suspended, faces skyward in midair at universal studios. Nearly 167 feet up. That's as high as a 17 story building. Stuck there for nearly 3 hours. You see this person waiving an arm. Help did come, first park officials climbed up and handed out water then the fire department. You're going to be a little bit upset in that position. Once we got up there, the guys were able to talk to them, calm everybody down. Reporter: More than two hours later they were helped into harnesses and delivered back to earth one by one. A similar glitch stopped a ride at six flags over texas in 2011. Nobody was hurt. But a woman died after falling out of that same texas ride this past summer. Today we climbed the ride at the fun spot amusement park with reviewer rob alvee. You can see all of orlando here. Accidents are rare. You're more likely to get in a car accident, win the lottery and get struck by lightning all in the same day than having an incident on a roerl coaster. Reporter: Still parks and fire officials practice drills for these scenarios several times a year. Don't freak out. Stay calm. Reporter: Matt gutman, abc news, orlando.
