Log Flume, Castle Park, Riverside, California, USA

A family of three was thrown from the log flume ride when a pump malfunctioned, preventing the flow of water onto the track. The log descended from one of the drops and there wasn’t enough water to slow it down causing the log to overturn, ejecting the family. The mother was hospitalized in critical condition, while the father and 10-year-old son were treated for minor injuries. Source (w/video)
