2012 WindSeeker incidents

During the 2012 season, all WindSeeker installations, with the exception of the Kings Island's location, experienced issues with its safety mechanism that would engage and strand riders in the air. Knott's Berry Farm experienced two occurrences, and in one of those, riders were stranded for nearly four hours. The California Occupational Safety and Health Administration ordered the closure of the ride on September 19 pending an investigation into the cause. On September 21, Cedar Fair made the decision to close all WindSeekers, pending an internal review. An evacuation system designed by the ride's manufacturer, Mondial, was installed at all Windseeker locations, beginning with Knott's Berry Farm. The system involves an employee riding in a metal cage that ascends the ride's shaft, enclosing up to four seats to safely evacuate riders.
