3. Rescue crews were called to the ride around 2:30 p.m. ET Sunday, according to the Associated Press. It took more than four hours to rescue all of the passengers.
5. Some people were stuck as high as 79 feet off the ground, at the highest part of the coaster.
7. Passengers were helped into a “rescue bucket” and lifted into the air by a 105-foot tower ladder before being placed on the ground, according to NBC News.
11. A spokesman for Six Flags America said in a statement that it has not been determined what caused the ride to stop but that it has a computerized safety system that “performed as it is designed to.”
13. The Joker’s Jinx is designed to go 60 mph and flips upside down four times. The ride was added to the park in 1999.
15. After more than four hours, all 24 passengers were rescued and evaluated by EMS before being released.
