If I’m the astronaut stuck in the ISS I’m refusing to return on that leaking time bomb and I’m begging NASA to have Elon bring me home in a Space X capsule.
Even if the two astronauts wanted to -- and Butch said before the first delay of the launch went all cheerleader and said Starliner was the only craft he'd fly on -- I think NASA gave them and Boeing a hard no, but privately.
