Over here trying to find why because the headline, summary, and tweet don't say it..

A valve failed testing on the rocket portion of the stack.

"The decision came after the United Launch Alliance team, which assembled the Atlas V rocket that Starliner will ride to space, identified an issue with a valve on the second stage, or upper portion, of the rocket."

That's how it's supposed to work in rocketry. Test, fix, test, then fly.

It's all in the linked article. It won't fit in the headline.

"Sticky valve grounds Starliner rocket"

I didn't hear this from you when Musk was having issues?
But as I stated, this is how technology advances.

SpaceX engineering has never had concerning issues, minus that Starship test that was slow responding to the self-destruct, Falcon is a lot of COTs repackaged with landing legs. It's the business model that's sus.

And then when a door

You should be old enough to remember AAF 243. They made movies about it.
