looks like you can't off two whistleblowers a week before the literal door falls off one of your airliners in midflight without taking a couple HITS to your BOTTOM LINE
Some of those checkouts are focusing on the potential effect of helium leaks, five of which have been detected on Starliner to date. One was spotted before launch but eventually deemed to pose little risk to full mission success. Four more have now been discovered while Starliner is in space, but that isn't necessarily cause for alarm.
You could leak a whole lot worse things than helium. But fuck me you can do a whole lot better. They didn't replace the leaky valve prior to launch because it was "too involved" to do so.
