Edit: Also that entire culture and dynamic between Boeing and Spirit on the production floor seems very toxic and driven by misaligned incentives. There should be zero place for bickering, aggressiveness, and finger pointing in that SAT channel. If something needs to be fixed Spirit needs to fix it with a smile. If Boeing and Spirit need to review who is responsible for what, and what needs fixing and doesn't, that should happen in review in a different setting. The production crews need to be able to execute on their processes and focus on the quality of the product without having timeline and budget concerns seeping into their day-to-day.
