PITTSBURGH (KDKA) — A ride at Kennywood briefly stopped working Monday, leaving riders hanging upside down. 

The Aero 360 got stuck mid-ride and left riders hanging upside down in front of a crowd of onlookers. In a statement, Kennywood General Manager Mark Paulus said the ride was "quickly" brought back to its "designated rest position." The statement did not say how long the ride was stuck.

The riders were evaluated by medical professionals, and Paulus said three of them visited the First Aid Center as a precaution. 

"Safety is our first and foremost priority," Paulus' statement said. "The ride remains closed while a review of the incident is conducted."

On its website, Kennywood describes the Aero 360 as an "intense" ride that offers a chance to "travel upside down while riding the iconic Kennywood arrows."

"With legs dangling, riders swing back and forth attached to a familiar yellow symbol—the Kennywood Arrow! The arrows swing higher and higher with each pendulum motion, culminating in a 360 degree over-the-top experience," the ride description says.

Kennywood Park staff addressed a ride stoppage earlier today on the Aero 360.

Maintenance staff responded, quickly brought the ride back to its designated rest position, and safely evacuated the riders.

First Aid staff met with the guests, with three briefly visiting the First Aid Center as a precaution before being released back into the park.

Safety is our first and foremost priority. The ride remains closed while a review of the incident is conducted.
