Thai cave rescue: First of the trapped boys emerge

Rescue efforts are underway and hopes are high, after 12 boys and their soccer coach trapped in a Thai cave for more than a week were found alive.

(CNN) — Four of the 12 boys who have been trapped in a flooded cave in northern Thailand for more than two weeks have been rescued, as the operation was put on hold overnight to allow oxygen tanks to be refilled.

The mission to free the remaining members of the group has been suspended for at least 10 hours, Chiang Rai Governor Narongsak Osotthanakorn said, as teams replenish supplies used up removing the first four boys.

But authorities face a new race against time as heavy rain, which had been predicted later this week, pummeled the cave complex in northern Thailand shortly after the first boys were freed.

The boys, who are due to be taken to Chiang Rai hospital for further medical examination, are said to be in good health, with their condition described by officials as “not that bad.”

Confirmation of the initial rescue was posted on the Thai Navy SEAL official Facebook page late Sunday evening, several hours ahead of the initial schedule provided by authorities.

The first of the four boys emerged from the cave entrance about nine hours after a team of 18 international cave diving experts entered the underground chamber to begin the hazardous process of accompanying the boys through the flooded, narrow tunnels to safety.

Previously, the entire round trip through the cave network was thought to take roughly 11 hours to complete, but efforts to drain the tunnels of flood water appear to have shortened the journey time by at least two hours.

After the rescue, Osotthanakorn told a press conference that “it was a very smooth operation today,” adding that he was “very grateful” to the teams involved.

While the governor would not confirm the identities of the four boys, he said the first one emerged at 5:40pm local time, followed by the second boy 10 minutes later. Two other boys emerged from the cave at 7:40pm and 7:50pm local time.

Families of the children have been waiting anxiously for news following authorities’ decision to initiate the rescue attempt at 10 a.m. local time Sunday, as storm clouds threatened to dump more water on the flooded caverns, undoing efforts to drain them.

“Today is D-day,” Osotthanakorn declared earlier in the day. “We have been waiting for this right moment.”

Twelve boys — aged between 11 and 16 — and their coach, were discovered by two British divers on July 2, nine days after they disappeared during an outing in the Tham Luang Nang Non cave complex, in Chiang Rai, northern Thailand.

Those still inside the cave are perched on a small muddy ledge four kilometers (2.5 miles) inside the cave complex, surrounded by flood water and with a limited supply of oxygen.

Race against time

For the boys, the most dangerous part of the journey out of the labyrinth cave system remains the first kilometer, in which they are required to pass through a flooded channel no wider than a person. During this process, rescuers need to hold their oxygen tanks in front of them and swim pencil-like through submerged holes.

Having completed this section, the boys are then handed over to separate, specialist rescue teams, who help assist them through the remainder of the caves, much of which they can wade through.

But rescuers have a dwindling window of opportunity, with forecasters predicting the return of heavy monsoon rains in the coming days, effectively sealing off the cave until October.

“We have two obstacles: water and time. This what we have been racing against since day one. We have to do all we can, even though it is hard to fight the force of nature,” Osotthanakorn said earlier, as rain began to fall across the site.

A rescue mission like no other

Divers have previously described conditions in the cave network as some of the most extreme they have ever faced.

The decision to move the boys using divers has not been taken lightly. On Friday, a former Thai Navy SEAL died while returning from an operation to deliver oxygen tanks to the cave where the boys are located.

Finnish volunteer diver Mikko Paasi, a long-term resident of Thailand, said the death of the Thai Navy SEAL had changed the mood on the ground and made real for rescuers just how dangerous the mission had become.

“Definitely, you can feel it that it has an effect, but we’re moving on. Everyone is a professional so we’re trying to put it away and avoid it happening again,” he said, adding: “Everybody is focusing on getting these boys out — keeping them alive or getting them out.”

Parents’ constant vigil

In the hours preceding the rescue, a letter the boys had sent to their families was published on the Thai SEALs’ Facebook page. The letter shows the boys in good spirits despite their ordeal.

In neat blue handwriting, 11-year-old Chanin Viboonrungruang, the youngest of the group, told his parents not to worry, and said he was looking forward to eating fried chicken.

His parents, who along with other families, have maintained a constant vigil at the site since the boys first became trapped.

On reading the letter Saturday evening, Chanin’s father, Tanawut Viboonrungruang, said he felt a great sense of relief. “I had been worried about my son, that he would be exhausted, he would be tired,” he said.

Now, more than two weeks after their children became trapped in a flooded cave, some of the families are finally celebrating their return.
