The M/S Explorer cruise ship sinks hours after hitting an iceberg off the coast of the Antarctic, in this photo released by the Chilean Army, November 23, 2007. More than 150 passengers and crew escaped unhurt after a Norwegian passenger boat in the area picked them up from the lifeboats they used to escape the ship, which ran into problems off King George Island in Antarctica at 0524 GMT, the company running the ship said.
