  1. David Jacobson — There is no instability caused by the new engines. They have greater takeoff thrust, so the pitch-up moment is correspondingly greater. This requires in reased trim in certain situations. That is not instability, it is merely a matter of trying to make the handling characteristics feel the same.

  2. The delay is due to the FAA, not Boeing, so the headline is a bit misleading.
