KANSAS CITY, Mo. — What was supposed to be an exhilarating day at Worlds of Fun turned into a harrowing experience for some visitors when a ride on the Mamba roller coaster took an unexpected turn.

On October 11, a couple enjoying the ride on the park’s tallest coaster heard a startling revelation from a young girl seated behind them. She announced that her seat belt was unfastened.

“It was completely undone,” recounted Chris Evins, who took swift action to ensure her safety. “There was a significant gap between her and the lap bar.”

As the 205-foot-tall coaster continued its course, Evins and his wife held onto the girl and her companion, ensuring their safety throughout the ride.

“I reassured her, ‘You’re going to make it through the rest of this ride. We won’t let you go,'” Evins shared.

Cassie Evins said both girls were crying as they held on.

“72 miles an hour, holding onto somebody. It’s terrifying,” Cassie Evins said.

One day after that incident, a guest reported another alleged seat belt malfunction on the Mamba.

A mother said she shouted that her son’s seat belt hadn’t locked as the cars entered their first climb.

This time, the ride reportedly stopped, and the seat belt, which the mother said was twisted and loose, was adjusted.

“We probably won’t go back for a while,” Cassie Evins said. “We need to see the change, and once we see that change, I will be comfortable taking my four children, who I am not comfortable taking currently.”

Inspectors from the Missouri Division of Fire Safety reportedly went to evaluate the coaster Thursday morning.

They told one of the affected guests that a ride inspector discovered some restraint devices that were “not functioning properly” on the Mamba, and the ride was taken out of service until repairs were made, which were expected to be done Thursday or Friday.

KMBC 9 reached out to Six Flags, the parent company of Worlds of Fun, for a statement on the situation.

“The safety of our guests and team members is a top priority,” a park spokesperson said. “Following the report of a guest concern on the ride earlier this month, our team immediately closed the ride and completed a thorough inspection before reopening it that evening. The ride is equipped with a multi-layered restraint system, and it has operated safely since the initial concern was raised.

“The ride has undergone a comprehensive safety review, and we have implemented modifications requested by the Fire Marshall to ensure it meets or exceeds all applicable safety standards before it reopens to guests this evening.”
