First of all, we are all aware that not all the information on MCAS was provided to us. This was one of the important things that came out. It makes us realize that we're going to have to be very careful about this kind of thing when we do certification in the future, and we certainly will be.
In its relationship with Boeing, the FAA is rethinking—it's one of the things that was done at the Certification Management Committee—the way it delegated the task of doing the certification to certain people, which allowed Boeing to select the people.
In some cases, this has resulted in the emails you mentioned. Frankly, it was quite shocking to read those.
