ANSAN, South Korea: Student survivors of South Korea’s ferry disaster testified on Tuesday on how passengers, abandoned by the crew, improvised means of escape, using fire hoses to pull people to safety as the vessel sank. On a second day of student testimony in the trial of the Sewol ferry’s captain and 14 crew, more than a dozen high school teenagers recalled the trauma of the April 16 tragedy that killed 250 of their classmates. One spoke of how she was saved by the actions of an adult passenger as sea water flooded into the heavily listing ferry. “At first, someone lowered a strip of window curtain that I grabbed on to, but then I slipped back down,” the student said. “Then a passenger threw me a fire hose and I tied it around my hips and he pulled me up,” she added.
