Four more boys rescued from cave in Thailand
Link here.
Keep your fingers crossed. What I did not mention yesterday in describing the dangers of cave diving was the truly courageous work of the divers to find these boys. Caving diving is mostly done blind. The first person in can sometimes see, but very quickly the silt reduces visibility to zero. To make sure divers can find their way back, they lay a lifeline as they go.
There had not been a lifeline to the passages where the boys were found, prior to this rescue effort. To have laid out a lifeline in passages almost two-thirds of a mile long, so quickly, speaks volumes for the courage and skills of the cave divers here. It is also why I am not surprised one diver died in the effort.
