On Sunday, four people were injured when a decorative aircraft fell from the ceiling of an indoor water park in New Jersey. According to the park’s website, videos from the scene appear to show the helicopter, which had been hanging from the ceiling of DreamWorks Water Park, laying upside down across the slides in the Penguins Frozen Fun Zone.

According to CBS New York, four people were treated at the scene for minor injuries, and one of them was transported to the hospital. The park, located within the enormous American Dream mall in East Rutherford, New Jersey, is North America’s largest indoor water park. Per a tweet from the mall’s account, the park will be closed until Thursday.
