I'd like to ask a brief question about the angle-of-attack disagree alert safety option. You spoke to this before. I believe you characterized it as a “red herring”.
I'm a lay person. It seems this is a safety feature that was offered by the manufacturer as an option to the airlines that were purchasing the aircraft.
Why did you choose not to purchase that safety feature? That's my understanding from your previous comments. Also, were there ever questions raised about why that safety feature was being offered in the first place? My understanding is that this safety feature alerted pilots to the problem that Boeing was aware of and had concealed.
