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.
