During the Thai Cave Rescue, many people, government agencies and companies for the international community offered to help. One of the notable person cum company is Elon Musk(Tesla/SpaceX). Elon took to twitter not only offering ideas, like the vacuum balloon but also activated a team in his company to build, test and send a miniature submarine to the rescue. Many have criticized Elon over his tweets and actions during this crisis, but in times like these or worst a helping hand or two can be just the life-saver.
Here's an excerpt from the Independent:
"[Elon Musk has for the past few days been promoting his Space X company's solution to freeing the trapped boys - an advanced miniature submarine.
However, while it was in development and transit to Thailand, it appears to have been rendered redundant by the fact that the mission to free the boys is almost complete, using conventional diving methods.
Asked at this morning's press conference about Mr Musk's offer, the head of the rescue mission, Narongsak Osatanakorn, confirmed that they would not be able to make use of the submarine.
He recognised the effort made by Mr Musk and his team, but said that "the equipment they brought to help us is not practical with our mission".
He added: "Even though their equipment is technologically sophisticated, it doesn’t fit with our mission to go in the cave.]6""
