I’ve read the book - it’s excellent and heartbreaking. The pendulum of safety swings back and forth - Columbia was 17 years after Challenger. Granted, we aren’t flying it anymore, but in terms of human spaceflight at NASA it’s been 21 years since Columbia. Everyone is hypervigilant and risk averse for a time as the lessons that were learned are still being discovered and people want to know how to avoid doing that thing again.
But over time, memories fade, people come and go, knowledge is lost and forgotten. And now with commercial space - “move fast and break things” if you will - they don’t like government or regulations or being told no.
So IMO, it’s just a matter of time until something else goes terribly wrong. For all of NASA’s faults, they did take the time to learn both culturally within the organization and technically (I can personally attest to this). They paused the program for a couple of years after both Shuttle accidents to learn how and why they failed.
That’s important and I’m not optimistic that those hoping to profit off of human spaceflight will be inclined to do the same when they fuck up.
