The wreck of the Costa Concordia cruise ship in front of the harbor of Isola del Giglio, Italy, after it was refloated using air tanks attached to its sides, on July 22, 2014. The Costa Concordia is now being towed away from the spot where it crashed on the night of January 13, 2012 in a disaster that killed 32 people. The ship's final journey for scrapping in the port of Genoa in northwest Italy is set to take four days. #

Members of the US salvage company Titan and Italian firm Micoperi work at the wreck of Italy's Costa Concordia cruise ship, on September 15, 2013. Salvage workers were preparing to right the ship in the largest and most expensive maritime salvage operation in history, so-called "parbuckling", to rotate the ship by a series of cables and hydraulic machines. #

The ship's horn sounded for the first time since the January 13, 2012 tragedy, its sound mixing with applause and cheers in the port in a dramatic climax to the massive salvage operation. #
