Oregon amusement park guests were left hanging upside down when a ride malfunctioned Friday.
Portland Fire and Rescue announced in a X post that they were called to the scene of Oaks Park after the "AtmosFEAR" ride, a spinning pendulum-style ride, malfunctioned on Friday evening.
The ride malfunction came on the park's first day of opening for the summer.
Officials said that approximately 30 people were stuck upside-down until help arrived.

Video footage, taken by Chris Ryan, showed the dozens of ride stuck vertically upside down at the ride.
"This isn't supposed to be like this," he said, showing footage of the upside ride with park goers gathered around at the base.
Ryan shared that one park employee said that this has never happened before at the park.
"That is actually f--king terrifying," he said. "I hope those people are okay."
Park engineers, alongside fire officials, worked together to "manually lower" the topsy-turvy ride, the department said.
A spokesperson for the Fire Bureau said the riders were being evacuated and medically evaluated.
"The ride has been manually lowered, and all riders are now being evacuated and medically evaluated," officials said.
Fire officials said earlier they did not believe anyone was seriously injured. The cause of the malfunction is unknown at this time.
Oaks Park officials did not immediately respond to Fox News Digital's request for comment.
