The wrecked Costa Concordia has begun its final voyage
Salvage crews refloated the ship last week so they can move it from its resting place off Giglio Island to the Italian port of Genoa to be dismantled.
On Wednesday morning, the rusting hulk set off into open waters under tow.
Attacked to its sides are the huge steel hollow boxes, or sponsons, that were pumped full of compressed air to give the ship buoyancy.
It's been more than 2½ years since the ship ran aground off Giglio Island with more than 4,200 passengers aboard, killing 32 people in a disaster that drew global attention.
The Costa Concordia is the largest salvage ever attempted -- and the most expensive, at a cost of $1.5 billion so far.
