Capt. Sully, interviewed by the Seattle Times, has spoken out on the 737 MAX return to service requirements as iterated by FAA. In particular, "Sully" identified concerns primarily about the crew alerting system, and the lack of a third AoA sensor input.

Perhaps of interest just to SLF and attorney types, there is no mention whatsoever in the interview as reported by the Seattle Times journalist about the FOIA lawsuit against the FAA, in which Mr. Sullenberger is prominent as a participant in the plaintiffs' expert-and-authoritative group of independent reviewers of the FAA documentary record sought to be disclosed by the lawsuit. Whether the lawsuit has become a less than fully relevant exercise is, to this observer, indeterminant at this time.
Quite possibly, the lawsuit might yet produce results, meaning that the independent reviewers might still have an adequate opportunity and predicate from which to develop and issue recommendations for safety-related steps beyond those being proposed by FAA. Indeed, Sullenberger's assessment reportedly contemplates expressly further improvements to the MAX to be implemented later, in accord evidently with EASA. Interesting.
