Musk shares video of pod made to rescue boys from Thai cave
Billionaire Elon Musk on Sunday shared a video of a 'kid-sized submarine' pod made by his company SpaceX that might help in the rescue of teenage football team trapped in a Thailand cave for two weeks. The submarine is constructed out of parts from SpaceX's Falcon 9 rocket. Musk said the submarine is small enough to get through narrow gaps.
