Oaks Amusement Park has filed a legal complaint against Zamperla, the manufacturer of the AtmosFEAR ride after a disturbing incident left riders dangling upside down. The complaint, which stems from a malfunction that occurred on June 14, was reported by KOIN. It details that 28 guests were trapped 50 feet in the air for roughly 30 minutes. The park accuses Zamperla of negligence and seeks compensation for all losses, costs, and attorney fees.
