The last person to be rescued from Italy's shipwrecked Costa Concordia has said he pounded on a wall with a frying pan to alert rescuers. Manrico Giampedroni, the ship's purser, waited nearly 40 hours before being rescued from the belly of the ship. He described falling through a door into the ship's restaurant as he tried to save passengers.
