Transportation Secretary Pete Buttigieg said his agency isn’t ruling out the possibility of “nefarious activity” being behind a computer outage that grounded all U.S. flights on Jan. 11.
The Federal Aviation Administration (FAA), which is overseen by Buttigieg’s agency, halted all domestic flights after a problem with the Notice to Air Missions system that relays real-time flight hazards to pilots. The cause of the hour-long outage hasn’t been determined.
