The blare of a ship's horn and cheers from the shore heralded the righting of the wreck of the Costa Concordia. The end of the operation off the Italian coast came in the early hours of Tuesday. It took a gruelling 19 hours to bring the ship fully upright, far longer than the 12 hours originally predicted. This is how it started a day earlier. The 114-and-a-half thousand tonne hulk was pulled upright by a series of jacks and cables.
