A waterslide malfunction aboard Royal Caribbean's Icon of the Seas cruise ship resulted in an injury to a passenger when an acrylic glass panel shattered. The incident caused water to spill down the slide, leading to panic among passengers. The injured guest was treated by onboard staff. Multiple videos captured the moment the glass panel broke, showing water pouring out and passengers reacting in alarm. The event occurred shortly before the ship's return to PortMiami. Royal Caribbean confirmed the injury but has not released further details about the passenger's condition.
