Boeing’s 737 Max software done, but regulators plot more changes after jet’s return

Boeing, regulators and airlines are cautiously optimistic a conclusion to the grounding of the 737 Max is realistically — and finally — in sight. That sets the stage for the jet’s return to flying around September at the earliest. All of this is happening while simultaneously plotting further long-term safety improvements to the aircraft to assuage regulator concerns, including adding systems to the Max that were previously rejected during the jet’s initial development.
