In the United States, there was a large-scale failure of the NOTAM system, which is responsible for warning pilots about possible dangers along the route or location that may affect flight safety. This is reported by Reuters.

The US Federal Aviation Administration (FAA) ordered all airlines to suspend domestic flights until 9 a.m. ET (4:00 p.m. Kyiv time) to give the agency time to verify the integrity of flight safety information. A total of 1230 flights were delayed, and 103 were canceled altogether.

According to the latest update from the FAA, flights have resumed at some airports.

It is currently unknown what caused the NOTAM outage, but US President Joe Biden ordered an investigation into the FAA‘s failure. Biden told reporters he had spoken with Transportation Secretary Pete Buttigieg, and they should have a couple of hours to figure out what caused the outage.

“They don’t know what the cause is,” Biden said. “Aircraft can still land safely, just not take off right now.”

I wonder if the Russians have something to do with it…
