Discovery, Askari Amusement Park, Karachi, Pakistan

A 12-year-old girl was killed and 25 others injured when a Chinese knock-off Discovery rotating pendulum ride collapsed to the ground. The frisbee style ride was close to the highest point of completing a 360° swing of its mechanical arm, when the ride broke apart. The new Askari Amusement Park opened on June 14, 2018, but the ride was recently installed on a “trail basis” according to park management. Source
