Riding a roller coaster can be exhilarating, but a few thrillseekers in Japan got more excitement than they bargained for.

Riders on the Flying Dinosaur at Universal Studios Japan found themselves unexpectedly suspended upside down, 100 feet in the air, after the ride stopped. They were suspended there, on an incline, for nearly two hours, HuffPo reported.

The Japan Times reported that the ride encountered an “abnormality.” There were two similar malfunctions last year on the ride.

Theme park staff worked diligently to release all 60 riders from their seats.

A spokesperson for the park told The Japan Times that “the suspension of the roller coaster was the result of the operator’s priority on safety.”

Luckily, no one was injured during the incident. The ride was reopened that afternoon, around 7 p.m., and while some visitors steered clear of the ride, there was still a line when operations resumed.

If you don’t already have a fear of heights, the sight of 60 people suspended in the air might make you think twice.
