Its not great, but not nearly as bad as Challenger SRB O-rings.

I was speaking more from the managerial and not the engineering point of view, when I made that comment about the vibes. How management politics underplayed problems until a disaster happened

My point still stands though. If the leak grows large during the trip, and all the helium escapes, then they can't maneuver the craft, which means they can't get at the right angle to reenter the atmosphere without burning up.

And if the shuttle tiles situation tells us anything, they don't take everything with them up into space, to do on-site emergency repairs.

Even if they brought extra helium with them, if the leak is widened (launch vibrations, etc.) to a point where the helium escapes too quickly now, before the whole reentry sequence completes, then they're stuck.

Just feels like driving a car across the Mojave Desert, with a known tire leak, and hoping the leak doesn't get any worse. Feels like a 'roll of the dice' moment.

No argument from me there. Starliner has been a mess managerial.

Halfway across the desert.

My point still stands though. If the leak grows large during the trip, and all the helium escapes, then they can’t maneuver the craft, which means they can’t get at the right angle to reenter the atmosphere without burning up.

If they dock successfully with the ISS, and before they leave they think there's any risk of lack of helium, they won't fly Starliner home. The crew of two could just stay safe on the ISS, and a Crew Dragon (with two empty seats) could be flown up to bring the Astronauts home safe. My guess is that NASA has done the math and it says this is an extremely unlikely scenario to have happen, but they could do it if they absolutely needed to.

I guess I'm used to the old NASA, where they would never 'play the Vegas odds', risk the astronauts under any condition, besides the normal risks of just launching in a rocket in the first place.

Interesting to see how having a private business corporation involved would change that mindset.

I do hope you're right, for the crews sake.

Imagine the PR nightmare for Boeing if they have to send a competitors spacecraft up to return the astronauts they launched? I’d almost wish for this to happen just for the embarrassment it would cause Boeing.
