Almost three years ago, the ferry Sewol sank in rough seas off South Korea. More than 300 people perished, mostly high school students on a field trip.
Now, South Korea's government is trying to raise what's left of the 6,800-ton ship. As NPR's Elise Hu reports from Seoul, nine of the people who were aboard that day in April 2014 remain missing, and families hope to recover those bodies once the Sewol has been lifted out of the water and put in dry dock.
Dozens of divers are involved in the salvage operation, Elise says.
