Nineteen divers are involved in the rescue attempt and officials said water levels remain stable, unaffected by the rain. Helicopters transporting the boys roared overhead. Last week, Musk sent engineers from two of his companies, SpaceX and Boring Co., to assist Thai officials in the rescue effort, which comprises a large team of global diving, engineering and medical experts, among other professionals.
Along with the rescue workers, the expected contingent of media from around the world have been on scene, including CBS News' Ben Tracy, ABC News' James Longman, NBC News' Janis Mackey Frayer and Bill Neely, correspondents from CNN, and extensive coverage on MSNBC and Fox News.
The Tham Luang cave system will now be closed for some time, prime minister Prayuth Chan-o-cha said. Once exclusive rights to the story are secured, the company hopes to work with a screenwriter to bring the tale to life. Among them was Umporn Sriwichai, an aunt of assistant coach Ekapol Chanthawong.
The disappearance of the boys and their novice monk turned soccer coach from this small town on the Thailand-Myanmar border - remarkably found alive nine days after they went missing June 23 - launched an extraordinary saga of global cooperation and ingenuity, as experts from many fields planned how to maneuver all 13 out alive.
A huge rescue operation is now entering its third day. The route, in some places just a crawl space, had oxygen canisters positioned at regular intervals to refresh each team's air supply.
Cave-diving experts had warned it was potentially too risky to dive the youngsters out.
They say the four boys and coach rescued Tuesday, after other rescues in the previous two days, are all safe.
Manchester United is greatly relieved to learn that the 12 footballers and their coach trapped in a cave in Thailand are. If they're chloroformed, how could they come out?
Jesada said the first four taken out are eating well.
Some of the children rescued even had a typical kid's request at the hospital after being trapped without food for so long - bread with chocolate spread.
The head of the rescue mission, Acting Chiang Rai Gov. Narongsak Osatanakorn, said 18 divers and a support team of 100 took nine hours in the second phase of rescues at the Tham Luang cave on Monday, as opposed to 11 hours on Sunday.
But two of the boys freed from the partially flooded Thai cave have suspected lung infections, following their 16 day ordeal underground.
"Great news that they made it out safely".
One of the Thai doctors said the boys were happy but psychologists would be evaluating them. "But we will have a psychiatrist to evaluate them".
There are concerns they may have consumed contaminated water, while bird or bat droppings could cause infections. But family members have seen at least some of the boys from behind a glass barrier. Rain fell periodically throughout the three days of extractions, but pumping efforts were so successful that the amount of time the boys spent underwater was minimized, officials said.
President Donald Trump congratulated the Thai SEALs on Twitter.
The eight boys rescued after being trapped for more than two weeks were described as generally healthy.
He added: "Such a lovely moment - all freed, great job!"
They are part of a youth soccer team known as the Wild Boars.
