Much as I like Muskey, his missions and products, he often comes across quite badly when discussing engineering.
Most top notch engineers are very detail heavy but EM just sort of sprinkles vague phrases in with little background.
His focus on polar moment of inertia in that interview was typical.
Maybe he doesn’t want to blind the interviewer with science or maybe he’s just so deep in so many topics it’s impossible to be an expert in all of them but he does come across as sort of faking it sometimes.
And yeah, Sandy should have actually let the guy speak a bit.
