A British diver who helped rescue 12 Thai school boys and their soccer coach who were trapped in the cave has slammed Elon Musk for creating a ‘child-sized’ submarine as a ‘PR stunt’ and said the billionaire ‘can stick his submarine where it hurts’.
Vernon Unsworth, a British caver who lives in Thailand lashed out after the Telsa CEO travelled to the country to build ‘a mini submarine’ that he said would help rescue the trapped boys.
‘It just had absolutely no chance of working. He had no conception of what the cave passage was like,’ Unsworth told CNN.

‘The submarine, I believe, was about five-foot-six long, rigid, so it wouldn’t have gone round corners or round any obstacles.’
Mr Unsworth knows the Tham Luang cave system where the boys were trapped very well, as he has spent years exploring it.
Musk was mocked online after the boys were rescued without the aid of his submarine – but he has hit back at critics and said the dive teams encouraged him to continue the work.
Musk tweeted a screenshot of an email from Richard Stanton, who co-led the dive rescue team, asking him to keep working on the submarine.
He said that ‘former provincial governor’ Narongsak Osottanakorn had been wrongly described as the ‘rescue chief’, adding that Osottanakorn – the man who rejected his sub – is no expert in cave rescue.
The actual expert, according to Musk, is a man by the name of Richard Stanton who encouraged him to build the submarine, saying it ‘may well be used’.

But he adds: ‘I don’t want to put it on a plane if you think important changes are needed.’
Stanton responds: ‘It is absolutely worth continuing with the development of this system in as timely a manner as feasible. If the rain holds out it may well be used.’
Elon answers: ‘Right now, I have one [of] the world’s best engineering teams who normally design spacesuits working on this 24 hours a day.
‘We are trying to get it right in a very short period of time.

‘If it isn’t needed or won’t help, that would be great to know. Otherwise, it would be very helpful to have as much design direction as possible.’
Musk also took to Twitter to bemoan being labelled a billionaire in reports about his involvement in the rescue – despite the fact he’s worth £15billion.
‘Ironically, the ‘billionaire’ label, when used by media, is almost always meant to devalue & denigrate the subject’ he said.
‘I wasn’t called that until my companies got to a certain size, but reality is that I still do the same science & engineering as before. Just the scale has changed.’
