Thai Crews to Hold Off on Cave Rescue Attempt

THAM LUANG CAVE, Thailand — An underwater effort to try to rescue 12 boys and their soccer coach stranded for two weeks in the flooded Tham Luang Cave will not be mounted in the immediate future, the commander of the operation said on Saturday.

With fair weather holding, crews will focus on bringing more oxygen to their cavern and drilling from above in the hope of reaching them, said Narongsak Osottanakorn, who is leading a rescue effort that has transfixed the nation.

Although three of those stranded had been described as weakening, Osottanakorn said the team was in relatively good condition overall.

“All the kids are healthy,” he said. “They are happy and they are safe.”

In letters home, written on water-stained paper and posted Saturday on Facebook, the boys and their coach sought to reassure their families that they were in good hands and in good spirits.

“Don’t worry about me,” wrote Ekkarat “Bew” Wongsookchan, 13. “I’ll be back soon.”

Crews on the mountain have drilled more than 100 holes — one of them 400 meters deep — but none has reached the cavern where the group is trapped.

“We don’t know where to drill a hole so that we can bring them out,” Narongsak said.

The oxygen level in the cavern, which has been measured as low as 15 percent, remains a major concern, he said. Crews are attempting to run a hose from the cave entrance to pump air into the cavern.

Fears that oxygen will become depleted had prompted the rescuers to consider an immediate underwater rescue, but that raised significant practical problems. Ferrying 12 children and one adult safely through a nearly 3-mile maze of perils is a daunting proposition, experts said, all the more so since none of the children are said to be able to swim, much less use diving gear.

“As you can see, all the officials have a mountain on their shoulders,” Narongsak said.

Some Thai officials have proposed leaving the boys and their coach in the cave for four months, until the water subsides and they can walk out. But Narongsak said it would probably take even longer — until December or January — for the water level to get that low.

“We are still in a war against water and time,” he said.

This is the monsoon season, and when heavy rains return, they could send a pulse of floodwaters through the cave complex, endangering the group. If that appears likely to happen, Narongsak said, officials could proceed with an underwater rescue.

“When we have no choice, we will have to make a decision,” he said. “We don’t want to make a mistake.”

Narongsak offered condolences to the family of Saman Gunan, the former Thai navy diver who died Friday after placing spare air tanks in a flooded passageway. And he thanked foreign divers who have come to assist in the rescue operation.

“They don’t know us,” he said. “They don’t know the Thai people. They are here to risk their lives for people they don’t know.”

In one of the team’s letters, posted to the Thai navy SEALs’ Facebook page, a boy expressed his gratitude.

“The SEAL team takes very good care of us,” wrote Panumat “Mix” Saengdee, 14. The divers have been bringing the team medical supplies and food.

The boys’ parents had written to them earlier. The letters, carried by divers making 6-hour trips in each direction, were the first direct communication between the parents and their sons. Attempts to establish a phone line to the cavern where the boys are trapped have not yet been successful.

“Mom, Dad, I love you guys, and little sister Toi,” wrote Pipat “Nick” Poti, 15. “If I get out please take me to a pork barbecue place. I love you Dad, Mom.”

The boys’ coach, Ekkapol Chantawong, wrote to the parents as a group, promising to take care of them as best as he could. The parents had written to him earlier, assuring him that they did not blame him for the situation.

“Thank you all for the support,” the coach wrote. “I deeply apologize to the parents.”

He also wrote to his own family members — an aunt and his grandmother — asking them not to worry too much about him. “Aunty, can you please tell granny to prepare vegetable juice and pork snacks?” he wrote. “I’ll eat them when I get out. Love you all.”
