More than 500 engineers from 24 countries have begun a make-or-break engineering feat to pull the crippled Costa Concordia from its side to an upright position in the waters off Tuscany, Italy. Never before have engineers tried to right such a huge ship so close to land. The goal is to raise it from its side by 65 degrees to vertical, as a ship would normally be, for eventual towing.
