Flights across the U.S. resumed Wednesday morning, several hours after the Federal Aviation Administration suffered a computer outagethat forced it to halt all departures nationwide while it scrambled to resolve the issue.
The FAA said the crippling delays that affected thousands of flights appear to have been caused by a problem in the Notice to Air Missions system, or NOTAM, which sends pilots vital information they need to fly.
A corrupted file affected both the primary and the backup systems, a senior government official said Wednesday evening, adding that officials continue to investigate.
