Flight disruption across the US on Wednesday was caused by a corrupted file database, the Federal Aviation Administration has revealed.

An estimated 10,000 flights were cancelled overall and the FAA tweeted on Wednesday morning to say it was ‘working to restore its Notice to Air Missions System’, adding: “Operations across the National Airspace System are affected.”

The FAA issued an update just after 12 noon GMT to say it had ordered airlines to pause all domestic departures until 9am Eastern Time (2pm GMT).

The system was back working shortly after – but schedules for the rest of the day remained affected.

The FAA said preliminary findings traced the cause to a ‘damaged database file’, which reportedly corrupted both the main system and its backup, the Independent reports.

An engineer ‘replaced one file with another’ without realising the mistake, a senior official told ABC News.

“It was an honest mistake that cost the country millions,” the official said.
