But this leads to a bigger problem. SpaceX's attitude of experiment vs. drawn-out design is working (perhaps not too dissimilar to agile vs. waterfall design). Even with all that careful planning, the Space Race did kill people, we almost lost Apollo 13, and there were two distinct shuttle disasters that killed everyone on board. Even with very careful progress, we still had disasters. But, as I think this launch shows, SpaceX is going to experience similar events unless there's a incentives and structures to actually empower people with safety concerns (meaning the engineers and technicians on the ground).
Both post-mortems on the shuttle disasters are filled with something like "a higher-up decided it wasn't that big of a deal and dismissed concerns because previous red flags turned out to be nothing." Single humans can be singularly stupid. Single humans that are busy running a company, incentivized by profit margins, isolated from on-the-ground operations, equipped with a golden parachute, and wealthier than god, are even more prone to detachment from reality.
I also feel a bit bad for the astronauts that have to gamble whether these rockets are safe. Did this actually pass safety checks or is my life a sacrifice Elon Musk is willing to make? I suppose this has been part of the calculus of all astronauts since the post-Space Race era started to defund NASA, but it still sucks even if it's de rigueur at this point.
