“Well, I just had a lot of talks with the team about that today,” he said of the SN1 failure. “It’s what you might call the thrust puck—there’s an inverted cone where we mount the three sea-level engines. In fact, it’s drawn on that whiteboard over there.”
He walked up to the whiteboard and pointed to a frowning face. “This is my drawing,” he said with a smirk. Then, with a dry-erase marker in hand, Musk proceeded to lecture about rockets.
“There’s a sad face because we have an inverted cone,” he said. “It’s such a dumb design. It’s one of the dumbest things on the whole rocket because it’s heavy, expensive, and unreliable.”
Basically, the SN1 failure boiled down to bad welds in a weak section of Starship near the engine. When exposed to pressure, the welds burst.
Musk was not happy because he had not heard about this specific issue, in this section of Starship, before the test failure. Do you think Musk addressed that with his team? Yeah, he addressed that.
“We sent out a note to the team that this was badly designed, badly built, and badly checked,” he said. “That’s just a statement of fact. I met with the whole quality team, and I said, ‘Did you think that that thing was good?’ They said, ‘No.’ I told them that, in the future, you treat that rocket like it’s your baby, and you do not send it to the test site unless you think your baby’s going to be OK. They said that they did raise the concern to one of the engineers. But that engineer didn’t do anything.
‘OK,’ I said, ‘then you need to email me directly.’ Now they understand. If you email me directly, and if I buy off on the risk, then it’s OK. What’s not OK is they think that the weld is not good, they don’t tell me, they take it to the pad and blow it up. Now I have been clear. There’s plenty of forgiveness if you pass me the buck. There is no forgiveness if you don’t.”
“I think we need, probably, on the order of 1,000 ships.”…
