@Nimbius666 I don't want to cheerlead for NASA (def not Boeing/SpaceX who exceptionally suck), every US astronaut death happened before the CMS flew people.
If you only count the time when both the CMS & NASA have been operating, neither have lost any people.
CMS has benefited from lessons from US and Russian/Soviet deaths. If the CMS had to learn these lessons from scratch they likely would have lost people. And apples to apples, all three are running 0 deaths in the time they've all existed.
