Back in the U.S., President Trump nominated former Delta executive and pilot Steve Dickson to lead the Federal Aviation Administration. The agency has not had a permanent head in over a year. Trump had wanted to nominate his personal pilot John Dunkin, but he faced scrutiny over his lack of qualifications. Dickson’s nomination comes as investigators are looking into the approval and development of Boeing 737 MAX 8 jetliners in the wake of two fatal crashes—last week’s Ethiopian Airlines Flight 302 and October’s Lion Air Flight 610 in Indonesia. Both crashes killed all crew and passengers on board and were found to have “clear similarities” based on early data.
