Except in this case, according to Steve Stich, it is NASA engineers vs. Boeing engineers. And the Boeing engineers are the ones who are "closer to the hardware", while the NASA engineers are just overseeing it.

I have no idea who is right in this case. And even if the crew comes down on Starliner successfully, it doesn't mean that it was the right call. Maybe they just got lucky.

My sense from the call is that, if NASA engineers insist on a Dragon return, NASA management will support them.
