It's a big question that I would also like to know, why did the ferry sink in the first place? Another thing that bothers me is that there was no announcement telling the passengers to evacuate but instead to stay put, with no further announcement. Many people were trapped in their cabins as the water was rushing into the ferry and I can only imagine how impossible it would be to escape. Many survivors stated that the ship was listing to it's side and still there was no announcement to evacuate the rooms and go up to there helicopters and boats were waiting.
"Passenger Kim Seong-mok told broadcaster YTN that after having breakfast, he felt the ferry tilt and then heard it crash into something. He said an announcement told passengers to not move from their places and that he never heard another about evacuating." - The Boston Glob.
Another things is that there were life boats and rafts aboard that ferry that were unused. The crew made a big misjudgment in this incident which is sure to cost many lives which could have been easily saved had they acted sooner and not waited until they were 100% sure they were going down.
This is a very tragic event and I pray that more people are recovered even with the extremely small chance.
