Flight operations have resumed in the United States on Friday, announcing the end of a temporary ban on flights across the country.

This happened after an unusual ground stop was imposed at US airports due to a malfunction in the air traffic control communication system, causing more than four hours of severe disruption at various airports in the country.

US Transportation Secretary Sean Duffy told a press briefing at the White House alongside US Homeland Security Secretary Mark Wayne Mullen that the ban on ground flights affecting millions of Americans was lifted at 8:15 pm US time (01:15 GMT).

Sean Duffy warned that the effects of the suspension of flights would not be over immediately and problems could persist for the next few days due to disruptions in the system.

Between Friday and Saturday night, the announcement of the US Federal Aviation Administration (FAA) came out, in which it was said that "due to a serious malfunction in the communication system, flights departing across the country have been temporarily suspended due to security reasons."
