Damn you know they have real doubt about Starliner with this decision. People were saying Nasa was just being super careful and the vehicle was perfectly fine like Boeing said. But with the astronauts being forced to use Crew Dragon, they can’t wear their space suits. Because the suits they use on Starliner aren’t compatible with all the SpaceX stuff. This can be a big risk, if there is a problem with the vehicle, the astronauts have no protection. But Nasa must have decided that was a smaller risk over using the Starliner. That says a lot.
