The Costa Concordia disaster was the partial sinking of the Italian cruise ship Costa Concordia had deviated from the ship's computer-programmed route, claiming that he was familiar with the local seabed. The collision with the reef could be heard onboard and caused a temporary blackout. The captain having lost control of the ship did nothing to contact the nearby harbour for help but tried to resume the original course. In the end he had to order evacuation when the ship grounded after an hour of listing and partly drifting. Meanwhile, the harbour authorities had been alarmed by worried passengers and vessels were sent to the rescue. During a six hours evacuation most passengers were brought ashore. The search for missing people continued for the next months finding all but two.
