In light of the costly flight control system glitch, President Joe Biden has ordered a full investigation into the causes. Some have speculated whether the technical failure could have been caused by a cyber attack but the White House says, so far, there has been no evidence to suggest this.
White House press secretary Karine Jean-Pierre confirmed that Mr Biden had been made aware of the Federal Aviation Administration (FAA) outage on Wednesday.
Writing on Twitter, she said: “The President has been briefed by the Secretary of Transportation this morning on the FAA system outage.
“There is no evidence of a cyberattack at this point, but the President directed DOT to conduct a full investigation into the causes. The FAA will provide regular updates.”
