The United States on Friday lifted an hours-long ground stop at the nation's airports, with top officials explaining that the disruption was not due to a cyberattack or a sweeping Microsoft outage. Transportation Secretary Sean Duffy said that US airspace was now "opened up," and blamed "old hardware" for the travel chaos.
The Federal Aviation Administration said Friday night that airplane departures can resume after the agency lifted a nationwide ground stop that Trump administration officials blamed on “overloaded,” “outdated” systems.
