All Flights Grounded Across the U.S.

The Federal Aviation Administration early Wednesday ordered airlines to pause all domestic departures until 9 a.m. ET to allow the agency to restore a critical system that alerts pilots and crew to safety advisories and other information for flights, the Wall Street Journal reports.

The White House tweeted there “is no evidence of a cyberattack at this point, but the President directed DOT to conduct a full investigation into the causes.”
