I think in light of MCAS every company operating Boeing aircraft should have reviewed their stance on operating Boeing aircraft.
And the worst thing is I don't think even after mcas things have substantially improved there. I've seen more spin and damage control than actual safety focus. They could have launched a huge company program and management reorganization to really turn this mindset around.
I think the biggest issue that Boeing is too big to fail. They'll never fall because the government needs them for all their warplanes.
