FAA employee explains possible cause of nationwide ground stop on flights: ‘Wouldn’t rule out cyberattack’

The Federal Aviation Administration (FAA) ordered a nationwide ground stop on all departing flights on Friday, citing “extraordinary circumstances and for reasons of safety.” While the agency has not publicly explained the cause.

But Washington Examiner journalist Anna Giaritelli shared a post about the outage, quoting an FAA employee who said the problem appeared to be serious because it was affecting a large part of the country.
