All flights in the United States are grounded due to “extraordinary circumstances,” the U.S. Federal Aviation Administration announced Friday.
The FAA issued the ground stop after a “communication issue impacting all U.S. Air Route Traffic Control Centers,” U.S. Transport Secretary Sean Duffy said in a social media post.
Airports in Toronto, Montreal, Edmonton, Calgary and Vancouver confirmed flights to and from the U.S. have been impacted by the grounding.
This is the first nationwide ground stop since January 2023 when a key FAA computer system malfunctioned. Before that the last time had been after the Sept. 11, 2001, attacks.
