  1. Fasfan, One of the best comments here, imho: 'Course that's only because you agree with me... 😎. Seriously, I think you understood the video in a way that maybe 80++% of the people here didn't.

  2. This twenty-minute video is a jewel: turn it this way and that and another facet sparkles. Getting to Mars is one Big Idea here. Beating the rocket billionaires is a side-show idea. The manager's clarity about how he manufactured the software to manufacture the hardware is an Epic Big Idea. And so it goes. Congratulations, Derek! Congratulations Relativity space! Thank you all: this is a head-spinner.

  3.  @russellstarr9111  (and Fred the Bulldog, above) This is an empirical question, but my instinct is with Russell and the guy giving the tour. I'm reminded that the Australian boat that won the America's Cup won with a roughened, not a smoothed, hull. I shall now toddle off and google up "Reynolds Number" -- something I knew about when I knew something about rockets -- fifty years ago!
