In a newly released video of the last minutes aboard the sunken South Korea ferry, students' nervous laughter, clowning and bravado gave way to panic and fear. "I'm really scared," a student says as the ship continues to tilt. "We're all finished," another one says. The shaky video was found on the cellphone of a 17-year-old student, Park Su-hyeon, when rescuers recovered his body.
