Billionaire tech mogul Elon Musk has apologized after he called a British cave expert who helped rescue a group of boys trapped in Thailand a "pedo."
Here's how we got here.
In case you missed it, a coach and his teen soccer team were trapped for more than two weeks in a cave complex, and Musk said he could rescue them with a mini submarine.
But Vern Unsworth, a British cave expert involved in the rescue mission, was not impressed with the idea.
