There’s a documentary about the rescue, I think it’s on Disney+. It was a mixed team, but the Thai military had no experience of diving in caves (albeit experts at diving elsewhere) and it was the international specialists who had the cave diving expertise, it was international doctors who worked out the drugs required to stop the boys panicking while ensuring the breathing was maintained during the extraction (from what I read it is much easier said than done). The Thai military provided manpower. As for the guy musk took offence with, he wasn’t fit to dive, but his knowledge of the caves meant they were actually found. Musk tried, he made a torpedo (unfortunately it was inflexible and too heavy to get round the bends so a non starter, but he tried), but what got people annoyed was he turned up with a camera crew to film him.
