South Korean ferry third mate was steering in tricky waters for the first time

There are new questions about why the captain of the South Korean ferry Sewol was not at the helm as the ship went through the most treacherous part of the trip.

The third mate was at the helm when the ship capsized. According to the New York Times, she's a 26-year old who had no experience navigating a waterway known for its rapid currents.

And it was only by chance that she was in charge - it just happened to be her shift when the ship got in trouble.

Chad Myers reports on why the waterway is so dangerous.
