General question.
NASA won't send crew up with Starship because it doesn't have a crew-abort system, like SLS, or basically any "conventional" rocket system.
But the shuttle didn't really have an emergency abort system either, other than dropping the shuttle off of the booster and fuel tank. Is the difference that Starship can't seperate from it's tank, because it's not like the shuttle could drop its internal tanks either.
That's a fair point. Imagine the cost just having a whole ass ship shitting there, doing literally nothing.
