A world askew: On board the Costa Concordia By all accounts, the Costa Concordia -- the half-sunken passenger liner marooned off the coast of Tuscany -- is a surreal sight. "You've got this giant thing that's three football fields long sitting on a slanted mountainside underwater," says 60 Minutes producer Rich Bonin, whose story on the Costa Concordia salvage project aired on the broadcast this week. It's like nothing you've ever seen before. But perhaps even more surreal are the images taken on board the vessel. In 60 Minutes Overtime's feature video this week, you'll see some of the first known video images shot aboard the ship since the accident. "You could see people walking across what used to be the side of the ship-- and is now the top of the ship," says Bonin. And the salvage workers hang their equipment on the very floor where the passengers used to sunbathe or sip their cocktails. Everything is just topsy turvy-- and those pictures have never been seen before. Twice the size of the Titanic, the ship remains in the spot where it sank about 11 months ago, and for the 60 Minutes crew, the challenge was to get our cameras as close to the hulking wreck as possible. One way Bonin's camera crew accomplished that was by flying miniature cameras above the ship, using remote-controlled drones. Camera operators steered the drones with a joystick from a nearby dinghy or from the shoreline.
