I was watching a documentary about the British cave divers on YouTube which was fascinating. They have carried out a number of rescues around the world and are known as the A Team. They were called in when someone was buried in an avalanche and they got him out safely, also in Mexico and in France. The Mexico one caused a bit of an international incident as the Mexican government offered help that was not accepted as they wanted to wait for the British team. The tracked the boys by footsteps but if you imagine looking for them in the dark with only torches while you are in water and mud it was quite a feat.
There are teams in the forest as well closing holes that would let the water in but also digging in places that look like possible entry ways. The cave hasn't been mapped so it is difficult to know what they would be digging down to and whether they would be near the boys.
People on social media who start comments with 'why don't they … ' annoy me. As if they aren't thinking of every possibility and facebook is the place to find an answer.

They are now saying the boys are not ready to dive yet and hundreds of people are in the forest trying to find a suitable site to start drilling a shaft above them. They need oxygen but also to try and get them out that way which would be a far better route than 6 hours through flooded tunnels.
