One week ago the cruise ship Costa Concordia ran aground off Isola del Giglio, Italy. Of the more than 4,200 aboard, 11 have been confirmed dead, 21 remain missing, and hopes of finding any more survivors are fading quickly. Rescue operations were called off earlier today amid fears the ship could quickly slip and sink deeper during worsening weather conditions. Captain Francesco Schettino remains under house arrest as investigators work to determine exactly what happened, and who was at fault. Rescue workers have spent the past seven days rappelling from helicopters, scaling the hull, scrambling inside and diving beneath the wreckage, racing against the clock to find anyone alive inside the massive wreck.
