Nothing works until 9:00 a.m. EST. The US aviation authority FAA has imposed a ban on all domestic flights in the United States, as the authority announced on the short message service Twitter. The reason is a system failure that could affect flight safety.

The system in which the so-called Notams (Notice to Air Missions) are published no longer worked on the night of Wednesday (January 11).

It was “failed” it was initially said on the website of the authority. Notams contain information that is important to personnel involved in flight operations but is not known far enough in advance to be published by other means.

All airlines and airports in the country are affected by the problem, chaos ensues in the terminals. The FAA is now trying to solve the problem. But it could be some time before the systems are up and running again. Hence the ground stop, as the ban on starting is called in technical jargon.

“The FAA is still working on full recovery,” it said. “While some functions are gradually being brought back into operation, the operation of the national airspace system remains restricted,” it said on Twitter.

US President Joe Biden was informed of the failure by the Secretary of Transportation in the morning, according to the White House. “At this time there is no evidence of a cyber attack, but the President has directed the Department of Transportation to conduct a full investigation into the causes,” spokeswoman Karine Jean-Pierre said.
