Quimera, La Feria Chapultepec, Mexico City, Mexico

Two men, aged 18 and 21, died when the wheel assembly of the last car came apart on the Schwarzkopf triple loop coaster, causing the car to fishtail and derail. At least two women were also injured. Eyewitnesses reported seeing a rider thrown from the car and other riders hit their heads as the flailing car was dragged around the track. Source
