Recovery workers face a grim and tough task. The safety of these rescuers has to be a priority.
The recovery operation began after the vessel sank 10 days ago but it still has some way to go.
US President Obama who visited South Korea this week as part of his brief tour of Asia spoke of his sorrow at hearing news of the tragedy.
At time of writing 187 bodies have been recovered but 115 are feared trapped.
The cause of the sinking is not known at this time. Investigators are checking whether a cabin refurb in 2012/2013 affected the ship's balance.
