A New Jersey theme park official said that the two people who broke down on Sunday were taken to the hospital while riding the popular log waterway at Six Flags Great Adventure.

The incident occurred around 6:30 pm, when the boat “did not complete its cycle,” a spokesperson said. One of the ships tilted at an angle, but not completely upside down.

The Saw Mill Log Flume ride takes guests to a four-story building and then slides them down a steep slope into free-flowing water. This attraction was one of the first attractions to open at the Jacksontown Amusement Park in the summer of 1974.

Six Flags emergency personnel assisted several guests at the scene on Sunday, and two of them were taken to the local hospital for evaluation. Their conditions were not immediately provided.

The spokesperson said: “The safety of our guests and employees is our top priority.” “The ride will remain closed for full inspection.”
