EAST RUTHERFORD — The waterpark at American Dream is finally open again with state approval after a prop helicopter fell into a kiddie pool and injured four people last week.

State police responded around 3 PM on Sunday, Feb. 19 after the blue prop, suspended by a wire rope four stories in the air, suddenly fell on top of swimmers at DreamWorks Water Park.

Three people, including an adult and two children, were treated at the scene, according to state police. A 33-year-old woman was taken to the hospital.

While American Dream closed the indoor water park immediately after the incident, the state Department of Community Affairs ordered it to stay closed until an investigation was completed.

According to DCA spokesperson Lisa Ryan, the firm found damage on the wire rope that had been suspending the prop helicopter. This damage was "a direct contributing factor" to the incident."

"This helicopter feature has been permanently removed," Ryan said in a statement. "The firm also deemed the current remaining features to be structurally sound and safe for continued use."

The American Dream water park reopened on Saturday with full approval from the DCA.
