Elon Musk's submarine was a PR stunt: Thai cave rescue diver
One of the divers who helped rescue 12 kids stuck in a Thai cave for 18 days, called Elon Musk's kid-sized submarine, which he offered to help, a "PR stunt" that "had absolutely no chance of working". "He had no conception of what the cave passage was like...It wouldn't have made the first 50 metres into the cave," he added.
