The perilous mission to evacuate 12 boys and their 25-year-old coach trapped deep inside a flooded cave in northern Thailand is under way, Thai authorities announced Sunday.
“Our readiness is at the highest today. Today is D-day,” said Chiang Rai’s governor, Narongsak Osotthanakorn, adding that the families had been informed of the plan and given their support to the rescue effort.
At 10 a.m. local time, an international contingent of 13 specialist divers and five Thai Navy Seals descended into the watery network of underground tunnels below the Mae Sai mountains, carrying with them the hopes of an entire nation.
The plight of the stricken boys, who have remained trapped inside the caves for 15 days, has transfixed Thailand, as rescue efforts have become ever more urgent.
Rescuers have what has been described as 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,” said Osotthanakorn, as a light rain began to fall across the site.
“All we need a suitable time window when all conditions are right to carry out the operation, we have been waiting for this right moment.”
At the entrance to the caves, volunteers assisting in the operation described the rescue attempt as a “now or never” scenario.
The boys and their coach are huddled together in a small chamber 4 kilometers (2.5 miles) inside the cave, surrounded by flood water and with a limited supply of oxygen.
To reach them, divers will need to successfully navigate a network of sprawling, narrow tunnels connecting the boys’ chamber with the rescue command center, known as Chamber Three.
Divers are expected to escort the boys through the tunnels one by one. Once they reach the command center, the boys will be handed over separate specialist rescue teams, who will assist them through Chambers One and Two, according to a Thai navy official with knowledge of the rescue operation.
“Today the water level in chambers number One, Two and Three inside the cave is low enough to walk through them,” said Osotthanakorn.
“The water of some parts recedes as much as 30 cm (11.8 inches), it is considered the lowest level for the past 10 days.”
Signs that a rescue operation was under way were evident in the hours leading up to the announcement, as authorities installed a large green tarp around the cave entrance and removed media from outside of the camp to a separate location.
On the dirt track leading to the tunnels, a near continuous convoy of trucks and military vehicles delivered troops and medical equipment, including a large cache of oxygen tanks. On Saturday evening, numerous international military advisers could be seen entering the site, followed later by four monks in orange robes.
At the entrance to the site, a newly placed, thin white decorative flag fluttered in the wind, a Buddhist sign to indicate positive energy.
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.
For families the wait for news of their boys’ rescue has been excruciating.
“I was worried about him as there are obstacles to extract him out. Everyone knows that it is difficult to stay inside (the cave) but the officials are trying (to help him),” said Viboonrungruang.
“I hope he is still healthy and would come out soon. I want to send my support to him. I don’t have a chance to talk with him,” he said.
