Oh, don't worry, we did figure that out. What we haven't figured out yet is how to stop Congress from involving themselves in engineering decisions.

Well, we should have figured that out with the STS. That's what the STS was for - figuring out what technologies made for inexpensive, rapid spaceflight and which technologies don't.

Then the senate mandates the new rocket to use specifically the most expensive, problematic, least reliable technology. Completely designed to fail.

Have such hopes for the Starship.
