For all those dumping on boeing (and I do my fair share of that, I will not fly on a 737 max or 787), given the timing this scrub was most likely due to something in the ULA centaur launch vehicle.
@arstechnica “You can imagine a large rack that is a big computer where the functions of the computer as a controller are broken up separately into individual cards or printed wire circuit boards with their logic devices," said Tory Bruno, ULA's president and CEO. "They’re all standalone, but together it’s an integrated controller."
What decade is this person living in? Or maybe his description is apt and the question is what decade the whole ULA is trapped in?
