> Transportation Secretary Sean Duffy said maintenance to upgrade an old telecommunications system may have triggered the rare, hours-long nationwide FAA ground stop. Officials are investigating whether contractor L3Harris made an installation error or supplied faulty equipment, and said they see no evidence of a cyberattack. The FAA expects schedules to recover by Sunday’s end.
