US Roller coaster rescue

It was a fun ride which went on far longer than expected! In the state of Maryland in the US 24 passengers had to be rescued by firefighters after a roller coaster train became jammed. For more than five hours passengers which included seven children were stuck atop the somewhat prophetically called "Joker's Jinx" ride while they were gradually brought to safety. Normally the roller coaster goes 75 kph and upside down four times. It is not clear what caused the problem but an investigation is underway. Fortunately there were no reported injuries.
