The Notice to Air Missions system, which sends out real-time
flights hazards and restrictions to all commercial airline pilots, has suffered
a nationwide outage, according to the U.S. Federal Aviation Administration on
Wednesday. 

While some functions have begun to come back online,
according to the FAA, it was still working to fully restore the system. The
agency has ordered airlines to “pause all domestic departures” until
9 a.m. Eastern Time to allow the FAA to “validate the integrity of flight
and safety information.” 

United Airlines sent a notice that it has temporarily
delayed all domestic flights.
