Riders on a roller coaster at Cedar Point theme park in Ohio were stuck on an incline for almost two hours on Monday afternoon.

Those who boarded the “giga-coaster” Millennium Force at Cedar Point on Memorial Day were expecting to rush down a 300-foot incline at 93 miles per hour. Instead, they were stuck on the ascent for almost two hours during a power outage.

A spokesperson for the park told the Associated Press that the power outage was caused when a car ran into a utility pole at about 1:45 p.m. Power was cut to almost one-third of the park’s rides.

“All of the rides that were affected safely came to a stop and all guests are being escorted off,” Cedar Point spokesman Tony Clark told The Toledo Blade.

Some roller coasters were able to move slightly during the power outage thanks to generators. Parks crew used emergency elevators to help evacuate other riders.

Those on the Millennium Force were stuck at an awkward angle high above the park, which some riders posted on Twitter.

Power was restored after about two hours, at 3:50 p.m.

Millennium Force was the tallest and fastest roller coaster in the world when it debuted in 2000.

Earlier this month, riders on a roller coaster in Japan were stuck upside-down for almost two hours when the ride malfunctioned.
