Two Rapid Unscheduled Disassemblies in one go. That's what I call efficiency.
But they really achieved a lot at the second launch, compared to the numbers of blown up rockets from NASA.
Yes I agree, they work much differently than NASA, a much better and faster approach I feel. The next attempt I am more confident they will get the Starship in orbit at least! Now it's just a matter of keeping those engine going when they should be going! I feel it's mostly these going out that are the biggest problem on the booster ATM.
