A communication systems failure has stopped takeoffs at every airport in the country. This kind of US flight suspension has happened only twice before, and the first came after the 9/11 attacks.

A nationwide halt on takeoffs is extremely rare in American aviation. Departures from all US airports have stopped only three times in history. The first time came after the terror attacks of September 11, 2001.
Why the US flight suspension began
The US civil aviation authority said earlier that a communication systems failure had grounded flights at every airport in the country. Officials will decide on arriving flights one by one. The problem touched about seven thousand aircraft, whether parked on the ground or flying in the air.
The last time flights were stopped
This US flight suspension is the first since January 2023. Back then, a fault hit the system that processes information bulletins for flight crews. Flights stayed on hold for 90 minutes. The ban covered more than ten thousand flights. More than one thousand of them were cancelled.
How it all started
The very first nationwide ban on departures came after the 9/11 terror attacks in 2001.
