Thailand cave rescue: All boys saved - how they did it

"We did something nobody thought possible," the leader of the Thai cave rescue mission declared today after the last trapped boys and their coach were finally freed, ending their 17-day ordeal. The dangerous, highly complex operation was launched after the group became stranded deep inside the flooded cave. They'll now be in hospital for at least a week, and they're being quarantined for fear of infection. Their families have only been able to see them through a glass window.
