They have been grounded worldwide since mid-March, after the second of the two crashes, an Ethiopian Airlines flight with 157 people on board. A Lion Air 737 Max went down in Indonesia shortly after takeoff on Oct. 29, 2018, killing all 189 people on the flight.Boeing said the changes will allow Muilenburg to focus on getting the Max back to service and that lead director David Calhoun will serve as non-executive chairman.”The board has full confidence in Dennis as CEO and believes this division of labor will enable maximum focus on running the business with the board playing an active oversight role,” Calhoun said in the statement.Muilenburg said he fully supports the board’s decision.”Our entire team is laser-focused on returning the 737 MAX safely to service and delivering on the full breadth of our company’s commitments,” he said in the statement.This is breaking news.
