All flights across America have been grounded this morning until at least 9am EST by an FAA systems failure that has left thousands of people stranded at airports..
The problem is with the Notice to Air Missions System, which pilots use to access flight paths and communicate with air traffic controllers about hazards.
That system went down sometime before 6am EST on Wednesday morning and as of 7.30am, it remains unfixed.
In the interest of safety, the FAA has grounded all commercial and private planes.
The cause of the failure is unclear. President Biden told reporters on Wednesday morning that he had spoken with Transport Secretary Pete Buttigieg and ordered a full investigation.
Planes can still land safely, but none are allowed to take off domestically for at least another hour.

All flights have been grounded until at least 9am EST which will have a knock-on effect on the 45,000 flights the FAA handles every day
Some 1,000 flights have already been delayed and the issue is likely to have a knock-on effect on routes for the rest of the day.
In pre-market trading, the shares of Delta, American Airlines and United all dipped slightly.
Transport Secretary Pete Buttigieg says he is in touch with the FAA and working to resolve the issue, while White House Press Secretary Karine Jean-Pierre said President Biden has been briefed.
There is no evidence of a cyber attack yet, she said, but the President has ordered the Department of Transport to conduct a full investigation.
In the meantime, thousands of people are stranded at airports across the country. Airport lounges quickly filled up as news of the outage spread, while some passengers were told by their airlines to simply ‘go home’.
In the first mention of the problem this morning, the FAA said in an alert: ‘The FAA is working to restore its Notice to Air Missions System.

The FAA’s announcement on Wednesday morning
‘We are performing final validation checks and repopulating the system now. Operations across the National Airspace System are affected.
‘We will provide frequent updates as we make progress.’
At 7am, the agency said: ‘The FAA is still working to fully restore the Notice to Air Missions system following an outage.
‘While some functions are beginning to come back on line, National Airspace System operations remain limited.’
Shortly before 7.30am, the FAA announced all flights were on hold until 9am.
‘The FAA is still working to fully restore the Notice to Air Missions system following an outage.
‘The FAA has ordered airlines to pause all domestic departures until 9 a.m. Eastern Time to allow the agency to validate the integrity of flight and safety information.’
NOTAM notices contain information essential to personnel concerned with flight operations, but not known far enough in advance to be publicized by other means.
Information can go up to 200 pages for long-haul international flights and may include items such as runway closures, general bird hazard warnings, or low-altitude construction obstacles.
The outage comes after federal officials said on Tuesday that they will require charter airlines, air-tour operators and plane manufacturers to develop detailed systems for identifying potential safety problems before accidents occur.
The Federal Aviation Administration said safety-management systems have made travel on large airlines safer since their adoption was required in 2018.
‘Expanding safety management systems to other players in the aviation industry will reduce accidents and incidents and save lives,’ acting FAA Administrator Billy Nolen said in a statement.
The National Transportation Safety Board, which investigates crashes, has pushed for wider adoption of such systems.
In 2020, Congress directed the FAA to require them for aircraft manufacturers after two fatal crashes involving Boeing 737 Max planes. The FAA said its proposal Tuesday went further by including smaller passenger-carrying operators.

In justifying expanding the requirement to smaller air operators, the FAA cited incidents including a 2015 crash of a float plane near Ketchikan, Alaska, that killed the pilot and all eight passengers.
The NTSB blamed pilot error and the company’s lack of a formal safety program.
The FAA said Tuesday that if its proposed rule had been in effect, the company would have taken steps that might have prevented the accident, including having a manager responsible for assessing safety risk.
The FAA has an explainer on safety-management systems, which have been a growing trend in aviation in recent years.
