The incident reportedly took place on June 6 at the Nandaihe amusement park in Qinhuangdao, Hebei province, China, according to local media sources.
An operating roller coaster unexpectedly derailed and halted at the highest point, leaving 11 passengers hanging upside-down in the air, according to a tourist’s video from the moment.
According to several witnesses, the park had an unexpected power interruption that left all roller coasters suspended in the air for more than 20 minutes.
