United States: Nationwide Flight Grounding Until Further Notice Following Rare Communications Outage

In a rare and extraordinary measure, the US Federal Aviation Administration (FAA), responsible for air traffic control in the United States, decided to ground all flights in the country until further notice, citing "exceptional circumstances" and reasons linked to "aviation safety and security."

US Transportation Secretary Sean Duffy explained on his "X" account that the administration imposed this comprehensive ground stop following a "communications issue directly affecting all air traffic control centers" across US territory.

Hostile Attack Hypothesis Dismissed

In an effort to contain concerns and reassure the public, US Secretary of Homeland Security Markwayne Mullin stated, in remarks reported by The New York Times, that "there are no indications at this point of a malicious attack against us; rather, it is currently just an outage in the communications network."

Speaking to media representatives at the White House, Mullin stressed that "this is not a 9/11-type event again." However, the secretary stopped short of completely ruling out any scenario, including the possibility of a cyberattack, acknowledging that authorities do not yet know the root cause behind this severe communications blackout.

Rare Precedent Since the 2001 Attacks

According to Reuters, this measure marks only the second time since the September 11, 2001 attacks that the United States has faced a complete standstill and a nationwide suspension of aircraft departures. The previous incident occurred on January 11, 2023, when the agency was forced to halt flights for approximately two hours due to a technical glitch in the pilot notification system.

Notably, this sudden disruption comes just days after the Federal Aviation Administration announced plans to begin the phased nationwide rollout of an advanced artificial intelligence-powered tool designed to assist air traffic controllers and reduce flight delays.
