Thousands of US flights grounded after computer outage

Thousands of flight delays and cancellations rippled across the U.S. early Wednesday after a computer outage led to a grounding order for all departing aircraft by the Federal Aviation Administration, according to a report from the Associated Press.

The stop order was lifted just before 9 a.m. EST, but delays and cancellations are expected to snowball. Nearly 5,000 flights were delayed and almost 900 were cancelled by around 10 a.m. EST. Departure gates at major airports are filled with aircraft that had been ordered grounded for hours. More than 21,000 flights were scheduled to take off in the U.S. today, mostly domestic trips, and about 1,840 international flights expected to fly to the U.S., according to aviation data firm Cirium.

While the White House initially said that there is no evidence of a cyberattack, President Joe Biden said “we don’t know” and told reporters that he’s directed the Department of Transportation to investigate the cause of the disruption.
