If I could just add to that, on the lines of communication, I'm sure none of us thought we'd become communications experts on MCAS. We're technical people, and we operate airplanes.
One of the things our airline did very early on—and we got great feedback for it—was to provide town halls and factual information to our employees, because if you don't have the buy-in of the employees to understand and ask questions, how can you ever go out and explain it to the travelling public? The facts matter. Those were certainly our efforts, and we'll continue to do that before we return to service.
