'FAA resumes full ops amid flight backlog...': Duffy breaks down events leading to FAA ground stop

Major airlines on Saturday (November 14) canceled more than 4,000 US flights and delayed 3,000 more as the United States sought to recover from the longest nationwide shutdown of flights since the September 11, 2001, attacks. The FAA on Friday issued a nationwide ground stop that halted nearly all departing flights for almost five hours due to a massive communications failure, which forced airlines to cancel nearly 10,000 flights and delay more than 7,000 others in one of the worst travel days in US history. Transportation Secretary Sean Duffy said Saturday at a press conference that FAA contractor L3Harris was working at a very remote location to convert a location from cooper to fiber.
