Boeing finishes software update for grounded airliner

Boeing says it has finished with its updates to the flight-control software implicated in 2 deadly crashes involving its 737 Max, moving a step closer to getting the plane back in the sky. Aviation regulators still have more questions about how pilots interact with the plane's controls under different circumstances, and Boeing says it is providing that information. The FAA, foreign regulators and airlines are reviewing Boeing's plans for additional pilot training, the company said Thursday. The next major step is a certification flight with FAA representatives. That flight has not yet been scheduled. "We're making clear and steady progress and are confident that the 737 Max with updated MCAS software will be one of the safest airplanes ever to fly," chairman and CE Dennis Muilenburg said. <br/>
