All flights across the US have been grounded due to a glitch with the Federal Aviation Administration's computer system, US media reports.

The FAA said it was working to restore its Notice to Air Missions (NOTAM) system, which alerts pilots of potential hazards along a flight route.

Some 760 flights within, into or out of the US have been delayed today, according to flight tracker FlightAware.com, while 91 have been cancelled.

Corrupted file to blame for computer glitch which grounded every US flight

A senior government official said the corrupted file affected both the main and backup computer systems used by the Federal Aviation Administration, causing thousands of flights arriving and departing the US to be delayed, with hundreds cancelled.

As far as I understand it:

• Until around 10 mins ago, there was no FAA directive (outside of United who were grounded in advisory 23). This means that airlines who could confirm they had current NOTAMs could depart.
• The FAA have now issued a directive which will see all domestic departures delayed for the next 2 hours.
