Airlines need to push Boeing into chapter 11, acquire a controlling interest, and install adults in charge who can deliver.
Much easier to get everyone in a room and say, "We're going to starve Boeing of revenue until it walks into Chapter 11, at which point we'll be ready to recapitalize and install new folks." Absolutely not my preferred thoughts on fixing a rotting enterprise, but you go to work with the tools you have.
And then there's, y'know, the whole DEI angle. Being acquired by the US Government isn't going to make them more likely to promote white male engineers to sort things out.
