There's an interesting parallel here to the incident in 2013[1] where a Nigerian ship's cook survived for 60 hours in an air bubble 30 meters under the surface in a sunken capsized tugboat. That was also a case where someone with no prior experience as a diver had to be extracted from a situation otherwise requiring some fairly advanced dive training. From the article: > The rescuing divers fitted Okene with a diving helmet so he could breathe while being transferred into a closed diving bell and returned to the surface for decompression from saturation. Okene lost consciousness during the transfer. According to the BBC[2] they'll probably end up doing something similar to extract those kids. They'd need to drag them over a long distance (probably one at a time) as "dead weight", but this method wouldn't require them to learn any diving skills. > The Thai authorities have appealed for donations of full-face scuba diving masks small enough to fit the boys in order to reduce the risk of their breathing apparatus coming loose as they travel through flooded passageways. 1. https://en.wikipedia.org/wiki/Aquanaut#Accidental_aquanaut https://en.wikipedia.org/wiki/Aquanaut#Accidental_aquanaut 2. https://www.bbc.com/news/world-asia-44692813 https://www.bbc.com/news/world-asia-44692813
