A computer outage at the US Federal Aviation Administration (FAA) has brought flights to a standstill across America, with hundreds of delays quickly cascading through the system at US airports.

The FAA ordered all US flights to delay departures until 9am EST (2pm GMT), though airlines said they were aware of the situation and had already begun grounding flights.
