- Musk said that he had made the claim out of “anger” because the diver criticized his idea to save a previously trapped Thai boys' soccer team with a "mini-submarine."
- The Tesla CEO had called spelunker Vernon Unsworth a "pedo guy" after the latter said Musk could "stick his submarine where it hurts."
- Venture capitalist Gene Munster called on Musk to apologize, saying his behavior was “fueling an unhelpful perception” of the exec's leadership.
The apology comes after the spelunker, Vern Unsworth, who was involved in the early days of efforts to save the now-rescued boys’ soccer team, threatened legal action against the billionaire executive over the comment.
Musk said on Twitter late Tuesday that he had made the claim out of “anger” because Unsworth had criticized his idea to rescue the boys with a “mini-submarine” made out of a SpaceX rocket part.
“Nonetheless, his actions against me do not justify my actions against him, and for that I apologize to Mr. Unsworth and to the companies I represent as leader,” Musk said.
“The fault is mine and mine alone.”
Musk got involved in efforts to rescue the group of 12 boys and their soccer coach earlier this month — mere days before their rescue. The boys had gotten stuck in the flooded Tham Luang cave in Chiang Rai after venturing through it with their coach.
He and a team of engineers from SpaceX and The Boring Company brought over the vessel — a cylinder made out of the liquid oxygen transfer tube of a Falcon rocket — to Thailand, and met with government officials there about the possibility of using it to help.
But Narongsak Osottanakorn, head of the command center during the rescue, did not welcome the idea, saying the sub was “technologically sophisticated” but “not practical” with the rescue mission.
Musk then hit out at reports referring to Osottanakorn as “rescue chief,” noting that he was the former provincial governor of Chiang Rai and claiming he was not the “subject matter expert.” Osottanakorn stepped down from his role to join the initiative.
Unsworth took a much harsher tone on Musk's submarine proposal, however.
The British diver, 63, called the project a "PR stunt" and said the billionaire could "stick his submarine where it hurts."
Retaliating on Twitter, Musk promised in a now-deleted series on tweets to release video footage of the submarine sailing through one of the caves. He then made the claim that Unsworth was a pedophile — calling him "pedo guy" — without offering any evidence as to the validity of the remark.
Asked whether he would mull legal action against the Tesla CEO over possible defamation, the cave explorer reportedly said: "Yes, it's not finished."
In Musk's apology on Tuesday, the executive appeared to take issue with Unsworth's comments denoting a sexual act involving the submarine.
Earlier on Tuesday, venture capitalist Gene Munster called on Musk to apologize, saying that his behavior was “fueling an unhelpful perception” of the entrepreneur’s leadership. Munster claimed to write on behalf of bullish Tesla investors.
The comments followed a rout in Tesla’s share price on Monday, as traders digested the negative publicity surrounding Musk.
Shares of Tesla barely moved in after hours trade on Tuesday, down about a tenth of a percent.
Traders are concerned about the automaker's production capabilities and profitability. Tesla achieved a goal of making 5,000 cars-a-week last month, but worries remain over the potential shortcuts taken to reach that target, such as eliminating brake tests in the final days of the production process.
