The Federal Aviation Administration, the US air transport regulator, has issued a "nationwide grounding due to extraordinary circumstances."
Fox News reports this as an exceptional measure, adopted only once since September 11th. The FAA has ordered all flights "to be grounded until further notice," citing safety reasons.
Secretary of State for Transport Sean Duffy explained that the disruption was due to a communications problem affecting all air traffic control centres.
