It was just a few weeks after President Donald Trump’s first travel ban. (AP Photo/Mark Lennihan)

FILE - This Dec. 7, 2015, file photo shows the second Boeing 737 MAX airplane being built on the assembly line in Renton, Wash. A new computer problem has been found in the troubled Boeing 737 Max that will further delay the plane's return to flying after two deadly crashes, according to two people familiar with the matter. The latest flaw in the plane's computer system was discovered by Federal Aviation Administration pilots who were testing an update to critical software in a flight simulator in the fourth week of June 2019 at a Boeing facility near Seattle, the people said. Both spoke on condition of anonymity because the development has not been made public. (AP Photo/Ted S. Warren, File)
