Just because they Said they could do it bu August, doesn't mean their attempt would succeed.
"We did it", ok. but did the speed run accomplish anything real except to check a 'boast box' for Elon?

Here's a nice summary of different rocket engine cycles:
Rocket engine cycles: How do you power a rocket engine?

I particularly like the idea of a dual expander cycle.
It feeds gaseous propellant to the combustion chamber
and it seems relatively simple and elegant compared to
other high efficiency alternatives.
Brain surgeons and rocket scientists no brighter than the rest of us, study finds | Neuroscience | The Guardian
It may not be rocket science, but researchers have found aerospace engineers and brain surgeons are not necessarily brighter than the general population.
So, what did they take away from this research?
“Essentially what we think it shows is that everyone has a range of skills, some people are better at some things and other people are better at other things"
So, this kind of research isn't exactly rocket science, then? 😉
