South Korean ferry disaster: Could air pockets save students on ship?

Searchers are in a desperate race to find the nearly 300 passengers who may be trapped inside a capsized ferry off the coast of South Korea.

A police chief tells CNN that authorities are working on the assumption that survivors are still in the ship. Divers are trying to find a way inside the ship that is mostly underwater. Their hope is to find students that are still alive - saved by pockets of air.

Growing desperation, anger as search for South Korean ferry survivors continues

Time is of the essence with temperatures in the water as cold as 50 degrees, and efforts to pump air into the ship have failed so far because of bad weather..
