## The Human Chain: Every Person Who Touched a Boy
The extraction sequence required more than the diving teams. Between the moment a sedated boy was placed in the water at Nern Nom Sao and the moment he arrived at an ambulance outside the cave entrance, he passed through the hands of dozens of people.
Inside the cave, the Thai Navy SEALs stationed at Nern Nom Sao prepared each boy for the dive: the full-face mask checked and sealed, the buoyancy device fitted, the sedation verified as taking effect. The diver received the boy at the water’s edge and began the transit. At intermediate air pockets, the diver paused to check the mask seal and assess the boy’s condition, re-dosing from pre-staged medication as needed. At Chamber 3, the diver handed the boy to the medical team waiting there.
The medical team at Chamber 3 — including the Thai military doctor who had been inside with the SEALs — assessed each boy immediately on arrival. They checked airway, breathing, circulation. They replaced the diving equipment with the emergency medical gear that would carry each boy through the remaining dry sections of the cave to the surface. They communicated the boy’s condition to the teams waiting further along the route.
From Chamber 3 to the surface, the boys were carried by stretcher teams through the dry sections of the cave. These sections, while not requiring diving, required physical effort: uneven ground, low ceilings in places, the weight of a sedated person on a stretcher. The stretcher teams were drawn from the Thai military, the rescue volunteers, and the international support personnel who had been staged at various points along the route.
