A waterslide aboard Royal Caribbean's cruise ship Icon of the Seas malfunctioned when an acrylic glass panel shattered as a passenger was sliding down, causing water to spill out and injuring the guest. The incident occurred shortly before the ship's return to PortMiami and caused panic among passengers on board. The injured man was treated by the ship's medical staff. Video footage captured the moment the glass panel broke, showing water gushing from the slide and shards falling onto the deck. Royal Caribbean confirmed the injury and the malfunction. Passengers have spoken out about the incident, and the injured guest featured in the viral video has announced plans to sue. The Icon of the Seas has experienced multiple incidents this summer, including a knife attack and now the waterslide accident, raising concerns about the ship's safety record.
