News agencies in Australia report that riders became trapped upside down for about three and a half minutes on the Doomsday Destroyer ride at WB MovieWorld when one of the safety sensors on the ride tripped and shut it down in mid-cycle. A video was shot by guests showing the arm of the ride stopped in the upside-down position, with ride’s legs dangling up in the air. The news reports that the riders were a bit shaken up by the brief experience, but I’m sure that the three and a half minutes spent stuck upside-down at the top probably felt like an eternity for them.
