US government grounds all flights across the United States 'due to extraordinary circumstances' | TechCrunch
TechCrunch reports that the Federal Aviation Administration grounded all US flights Friday afternoon, citing "extraordinary circumstances" and an "equipment outage," with departures held until further notice. An FAA spokesperson blamed communication issues at multiple air traffic control centers; the cause is unclear, though Homeland Security Secretary Markwayne Mullin said there was no indication of a nefarious act and warned recovery will take time.
