Elon’s daily dose. It takes a lot to get on his level.
Just kidding, but it seems like something to do with the fuel/exhaust.
I’ve read multiple articles and the most I’ve gotten is that their first launch didn’t have the cleaner fuel that future launches did. I am not sure how that would cause repeated incidents… perhaps it’s from metal parts in the rockets? 🤔 I could have missed something as I was reading but hopefully someone else will know the answer.
