Which is unforgivably low. Check the dates and see if you notice a modern-day program that’s overrepresented.

Space travel is dangerous and anyone who flies in space understands that and signed up for it. But the shuttle program had deliberately and pointlessly unsafe decisions that were taken for reasons of cost-cutting or simple management incompetence, and all the dead astronauts on those two shuttles are a direct result.

If you know you’re going to fly 135 missions, and you accept a 1.5% catastrophic failure rate, then you’re accepting blowing up two shuttles with everyone on board. Which is exactly what 1980s-era NASA did, not because it was an inevitable reality they couldn’t avoid, but because management had their heads up their asses and wasn’t invested in the idea of sacrificing their own convenience in order to keep the program safer than 1.5%.
