Who even needs a specific buyer? Boeing itself is a publicly traded company, the spin-offs can be too. Put the business unit into its own corporate entity and give all the shares of the new entity to the existing Boeing shareholders to do with as they please, or sell them into the market.

I was making the point that you're going to have a board filled with people who in some instances could be hand-selected to say the quiet part loud, and the list of companies who makes some of this stuff has one item in it.

Its military stuff.

There are more than a million people with a US security clearance. Finding enough to fill the board of a new company shouldn't be prohibitively difficult.
