A Carnival Cruise Line passenger is in critical condition after falling on the Carnival Valor cruise ship.
The US Coast Guard said the 23-year-old male passenger suffered "multiple significant injuries".
According to Business Insider, he was sitting on a railing on one deck and fell 16 feet backward onto a lower deck.
The accident occurred while the ship was sailing off the coast of Louisiana.
An MH-65 Dolphin helicopter took the passenger to New Orleans University Medical Hospital early Tuesday morning.
