They had paid to go on the Mumbo Jumbo ride at Flamingo Land theme park in North Yorkshire, which is claimed to be the steepest rollercoaster in the world
But their carriage got stranded after a poncho jammed the mechanism, leaving them upside down before being rescued by theme park staff.
Nigel Warburton, of Darlington, County Durham, who was at Flamingo Land for a day out, photographed the incident yesterday.
'There was quite a crowd gathered watching,' he told The Northern Echo.
