Another interesting tidbit:
Billionaire entrepreneur Elon Musk tweeted Monday that he had visited the cave and left behind a mini-sub rescue vehicle “in case it may be useful in the future.”
Just returned from Cave 3. Mini-sub is ready if needed. It is made of rocket parts & named Wild Boar after kids soccer team. Leaving here in case it may be useful in the future. Thailand is so beautiful. pic.twitter.com/EHNh8ydaTT
