Emergency crews in Oregon rescued 28 people Friday after they were stuck for about half an hour dangling upside down high on a ride at a century-old amusement park. Portland Fire and Rescue said on the social platform X that firefighters worked with engineers at Oaks Park to manually lower the ride, but crews had been preparing to conduct a high-angle ropes rescue if necessary. All riders were being evacuated and medically evaluated, and there were no reports of injuries. One rider with a pre-existing medical condition was taken to a hospital for further evaluation as a precaution, Oaks Amusement Park said in a statement posted on social media. Medics released all other passengers. The ride, called AtmosFEAR, operates like a pendulum, with the capacity to swing riders completely upside down. When the ride stopped, park staff immediately called 911 and emergency responders arrived about 25 minutes later, the park statement said. Park maintenance workers were able to return the ride to its unloading position minutes after first responders arrived. Portland Fire said about 30 people were on board. The amusement park statement said there were 28 riders. The ride has been in operation since 2021 and has not had any prior incidents, the park said. It will remain closed until further notice. Oaks Park first opened in 1905. Its website says it offers a “uniquely Portland blend of modern thrills and turn-of-the-century charm on a midway that has delighted generations of Northwesterners.”
