British divers make contact with missing Thai football team
How does cave oxygen supply work? Would they not run out of oxygen by the time they can get out?<p>Also, one detail that CNN got that I didn't see in this article: it seems the cave is <i>one kilometer underground</i>! [1]<p>EDIT 1: The CNN article partially answers my first question: <i>"Rescuers will also pump air into the cave to improve conditions."</i><p>EDIT 2: Another important bit here [2]: <i>"It won't be anything like diving that most people recognize. It will be diving in what is effectively muddy water, possibly fast flowing, with no sense of direction," Moret said. "You can't tell what's up, down, sideways."</i><p>[1] <a href="https://www.cnn.com/2018/07/02/asia/thai-cave-rescue-intl/index.html" rel="nofollow">https://www.cnn.com/2018/07/02/asia/thai-cave-rescue-intl/in...</a><p>[2] <a href="https://www.cnn.com/2018/07/03/asia/thai-rescue-next-phase-intl/index.html" rel="nofollow">https://www.cnn.com/2018/07/03/asia/thai-rescue-next-phase-i...</a>
