In this Monday, March 23, 2020, file photo, a worker walks near a mural of a Boeing 777 airplane at the company’s manufacturing facility in Everett, Wash., north of Seattle. Federal regulators have indicated they likely won’t certify Boeing’s next airliner until 2023 because of questions about changes the aircraft manufacturer is making in software and hardware on a new version of the two-aisle 777 jet.
