FAA ground stop lifted: Why were US flights grounded, and what’s next?

FAA grounds all fights across the US over ‘telecommunication outage’ The US Federal Aviation Administration (FAA) has lifted a nationwide ground stop imposed on Friday that halted departing flights, an order it issued citing “extraordinary circumstances and reasons for safety”. The halt, which grounded thousands of flights across the country, was lifted on Friday evening. This was the third nationwide ground stop of all departures since the September 11, 2001, attacks. “Everybody’s safe,” Homeland Security Secretary Markwayne Mullin said, adding that this was not “another 9/11”.
