JINDO, South Korea (Reuters) - For the parents of the many teenagers still missing after the Sewol ferry capsized off the coast of South Korea, the wait for news - good or bad - is almost unbearable.
Of 462 passengers on board the ship when it set sail from the port of Incheon late on Tuesday, nearly 340 are believed to have been from the same high school near the capital Seoul, on their way to Jeju island for a field trip.
