A glitch caused the park’s computers to go into safety mode which automatically stopped the ride. That was exactly what the ride was supposed to do in that situation; the problem was that it happened to be 140 feet above the ground at the time.
The roller coaster also couldn’t be started again, forcing a rescue.
"Being in that position, not knowing why you're in that position, you're going to be a little upset, but our guys were able to talk to them and calm them down," said District Chief Ian Davis of the Orlando Fire Department.
Universal engineers had to get the cars in a safe, locked position before the riders could be safely unloaded.
The roller coaster has had a history of starting trouble because of its difficulty getting started. Rip Ride Rockit was closed down in 2010, about a year after it first opened.
Universal Orlando said the ride was closed for maintenance, but the coaster's creator had warned of a manufacturing flaw just a week before.
"We are going to work to understand what happened tonight before we reopen the ride again," Schroder said after the coaster was stopped on Wednesday. Apparently park officials deemed that it was safe for Rip Ride Rockit to take off again.
