I already said the NASA/DoD program was scrapped in the 90s. They had successful sub-orbital test flights, the original designs were for an orbital craft, but the project was canceled before that could be tested.

I meant what advantages do they have to facilitate that. You gave me the outcome but haven’t shown any understanding of the why. When somebody asks what makes Tom Brady special, saying “because he wins more” isn’t really saying much and doesn’t take show you know much about football.

I ask because I suspect you will just give some rote public vs. private answer but that’s only a superficial reason. There are underlying systemic reasons, but you need to remove yourself of that false dichotomy first to get there.

FWIW, I’m not a big fan of NASA. I think they are largely a broken culture and a shell of what they were in the 1960s.
