They've found a new way to drive efficiency. Just blow 'em up on the ground without all that lifting into the upper atmosphere nonsense. Musk is a genius!!!
I understand Musk isn't an engineer, but he seems to like to play at being one. Like the story I've read of him getting onto some part of a Tesla production line and asking the workers why they use that many bolts in that stage of manufacture. Or his interview with Tim Dodd (Everyday Astronaut) which ended up in some change in the design of Starship.
I wonder whether the problems Starship has been experiencing over the last few months are anything to do with other tinkering by him. Or is it simply that the SpaceX engineers have pushed Starship beyond current technological limits?
