1FAA issues nationwide ground stop for all flights due to ‘extraordinary circumstances’ and safety
A nationwide ground stop in the USA has been lifted after an outage halted all flights. But the disruption’s ripple effects are expected to last for days, according to US Transportation Secretary Sean Duffy.
The grounding began at about 21:00 GMT on Friday and lasted about four hours. It was the longest in the US since the one after 11 September 2001.
Officials say the incident was caused by a “telecommunications outage” and that there’s no evidence it was a cyberattack. They have blamed old systems for the outage, saying it could happen again without a “complete overhaul”.
