SpaceX founder Elon Musk tweeted photographs and video of his 'mini-sub' that he has left in Thailand in an effort to help authorities rescue members of a boys' soccer team trapped in a cave.
Musk is in Thailand to tout his 'child-size submarine' that he says he is willing to leave in Thailand to help the boys - although with two-thirds of them rescued he may be a bit late.
On Twitter and Instagram, Musk posted images showing himself in 'Cave 3' - although there is no confirmation that that is where the trapped boys are located.
The prototype revealed by the billionaire Musk on Monday shows a large metal tube with a nosecone that is meant to serve as the mini-submarine that would help the members of the youth soccer team to safety.
Officials from Musk's Boring Company and SpaceX traveled to Thailand to offer their assistance, but it appears that the Thai government has managed without them.
