Luckily the riders stopped right-side-up, and park officials say they were never in danger of injury.
"All the guests are seated. They're not upside down or anything like that," said spokesman Jim Stellmack. "They're in a seated position, comfortably."
"They're kicking their feet and it doesn't look like anyone was in distress," said park-goer Brian Murrell. "Looked like a lot of people were handing them water and stuff, keeping them hydrated."
Firefighters were called in and had to pull each rider off the track one at a time from 100 foot ladders.
No one was injured, and the last rider was pulled from the coaster after 6 p.m.
A similar breakdown happened at the park 9 years ago, but no one was injured in that incident either.
Preliminary reports show the tracks lift chain malfunctioned.
Investigators say the ride will be reopened when the problem is fixed.
"Safety is our number one priority so we're taking it slow and easy to sure that we do this and don't have any issues as a result, " said Stellmack.
