are expected to begin sunday, threatening to wash away their efforts and their hopes of a timely rescue. more than two miles inside the cave, a supply of food and oxygen keeps the soccer team smiling, but medical experts say at least three of them, including the coach, are too malnourished to evacuate safely. still, 13 sets of diving equipment have been prepared in case of a hasty emergency exit. we just have to assess everything at the moment. we have to see what the conditions bring, what the water levels inside the caves do, and what options are available to us. reporter: after one failed attempt, communication lines are being fed again through winding stone in hopes of connecting those inside with rescuers and family above. it would be a much-needed boost, both for morale and expediency. translator: to deliver information from inside the cave, navy s.e.a.l.s have to dive for 11 hours. we spend six hours going in and another five hours coming out. this is our main obstacle.
