The tube or whatsoever was not used for that but surely will be useful one day. Appreciate to international who support teams and else as well. Narusorn, the musk submarine rescue idea, luckily wasn’t taken seriously, using professional cave divers resulted in the Avengers Endgame Dachshund Dachshundvenger shirt success, had anyone listened to the ridiculous submarine idea, it could only have ended in tragedy. Thankfully nobody, except musk, took it seriously. Just might have any use in the future. I’m not looking at Mr. Musk on the bad side. Good thing is that he is willing to help, even if not useful at that time.
