For hours, the United States experienced a halt to its aviation industry. It was not a cyberattack that froze the country’s air traffic, but a communication blackout rooted in ageing telecommunications infrastructure. The Federal Aviation Administration (FAA) issued a nationwide ground stop, a suspension of all commercial flights that resulted in thousands of flight cancellations and left hundreds of thousands of travelers stranded. It was the second such total stoppage since the 9/11 attacks, a disruption that sent shockwaves through the travel world.
The chaos began at 3:36 pm local time. At that moment, radar and communication systems at air traffic control centers and Terminal Radar Approach Control (TRACON) facilities across the country experienced instability. US Transportation Secretary Sean Duffy described the technical failure as ageing telecommunications infrastructure.
When the ground stop was issued, more than 3,500 aircraft were airborne. Duffy noted that authorities had to coordinate the safe landing of those thousands of aircraft. By the time officials began addressing the public, fewer than 400 aircraft remained in the airspace, having either landed or been held in safe orbits. Critical operations, such as medical evacuations and cargo movements carrying life-saving medicines, were exempted from the stop to ensure essential services continued.
Mullin emphasized that the investigation found no evidence of foul play.
#WATCH | FAA Grounding Issuance | United States Secretary of Transportation Sean Duffy says, "...At 3:36 p.m., we experienced instability in our radar and our communications in our centres and our TRACONs across the country... The TRACONs and the centres, we started to have inconsistency in the data from the radars and our communication with aeroplanes. And we have procedures for this. Our pilots are well-trained, our air traffic controllers are well-trained, and at that point we issued a ground stop. We had over 3,500 aeroplanes in the air. They all engaged, and last time I looked we had less than 400 in the airspace as they were all coming in to safely land, and we navigated it with our well-known procedures that we have when these incidents happen..." He adds, "...When we shut down the airspace, oftentimes there are critical movements that have to take place, whether it's medevac or cargo operations that are moving critical medicines that save people's lives. We didn't lose all TRACON; we didn't lose all radar, but that instability, because of abundance of caution and making sure we keep the American flyer safe, we did the ground stop, but we were going to allow those life-saving movements to still occur, as well as with law enforcement as well... I've heard a lot of the rumours like Markwayne has, but what we have is an incredibly old air traffic control system... The President, for the last year, has been asking Congress to fully fund a full build of a brand-new air traffic control system... It's the old hardware that went down..."

As news of the ground stop spread, speculation arose. Homeland Security Secretary Markwayne Mullin addressed these fears during a joint briefing with Duffy. He clarified that there is no connection to Microsoft. Mullin emphasized that the investigation found no evidence of foul play. "There is actually no cyber attack," Mullin stated. He explained that in typical cyberattacks, perpetrators often leave footprints, but in this incident, there was no visible malicious trace.
As the FAA began to lift the nationwide ground stop, the focus shifted to the long-term solution. The reopening of US airspace was confirmed. Duffy and Mullin used the briefing to urge Congress to act. The administration requested $30.1 billion from Congress to fund a comprehensive overhaul of the Air Traffic Control System. Duffy emphasized that the President’s administration is asking for the resources to modernize this critical infrastructure. For now, the skies have reopened, but the debate over upgrading the US air traffic control system remains.
Nearly 6,000 flights were cancelled, including some international routes, as Homeland Security Secretary Markwayne Mullin stressed that there was no evidence of hostile action. https://t.co/7g0JUQq9VU
