An amazing feat in a series of extraordinary events.
Now that the Thai football team has been extracted from their flooded cave complex, it's time to marvel at how the rescue was carried out.
Kiwi diving physician Simon Mitchell told Chris Lynch there's a real danger of under-appreciating the work the two British divers did to find the kids.
He says Rick Stanton and John Valanthen went into the tunnels in zero visibility, with a strong flow against their progress, feeling their way through a tunnel with lots of false leads all the time having to manage and carry their own oxygen.
"There's nothing for them to follow and the fact that they actually made it through and found those children is not short of extraordinary. And of course as they laid line it made it so everyone else could find their way through a lot more easily."
