Yesterday, April 16, 2014, off the coast of South Korea, a large passenger ferry named the Sewol sank in calm seas, while carrying more than 450 passengers, mostly high school students on an overnight trip to a tourist island. Officials currently confirm only 164 have been rescued, another four listed as killed, leaving approximately 300 passengers still missing. By nightfall, the Sewol had turned upside down, sinking nearly completely below the surface -- only a small part of its bow still visible. Reuters quoted one survivor as saying "The on-board announcement told people to stay put... people who stayed are trapped." As anxious relatives await word, officials have resumed rescue operations after a short pause during the darkest hours of the night.
