Sunken Ship Rescue
NOVA follows the epic operation to secure, raise and salvage the Costa Concordia cruise ship, which ran aground and capsized off the coast of Italy on January 13, 2012, killing 32 people. The wreck stretches the length of three football fields, weighs 45,000 tons and lay half submerged on the site of a protected reef, with a 160-foot-long hole in its hull. Moving it from its precarious perch on the edge of an underwater cliff is a huge technical and logistical challenge. NOVA joins a team of more than 500 divers and engineers working around the clock as they attempt the biggest ship recovery project in history.
