In the summer of 2018, twelve boys and their soccer coach were trapped deep in a flooded cave in northern Thailand. Saman Kunan had already left the Thai navy, but he came back to volunteer in the rescue. His job was to carry air tanks into the cave for the boys and the other divers. On the way back out, he ran out of air himself, lost consciousness, and died. The rescue went on, and days later every one of the boys and their coach made it out alive.
