Grounding all flights on 9/11 and preparing for the unpredictable









At 9:25 a.m. EDT on Tuesday, September 11, the Department of Transportation, via the FAA, ordered the U.S. National Airspace System closed to all civil flights at its 460 controlled and 15,000+ nontower airports. Canada’s Ministry of Transport followed suit within one hour.


Directed from the Air Traffic Control System Command Center at Washington Dulles, the FAA’s 17,500 controllers directed the landing of some 4,300 tracked airborne targets and ordered the diversion to Canada of 120 inbound overseas flights, while the remaining inbound airplanes returned to the countries of origin. Nav Canada landed the diverted traffic and its domestic airborne traffic before unplugging its service.

This unprecedented grounding of all civilian flights over an entire continent was subsequently described as 'organised mayhem'.

In the aftermath, attempts were made to find out how the grounding was actually achieved because there were no manuals or procedures for such an eventuality.

It turns out that when the thousands of Air traffic controllers needed to urgently find alternate landing grounds they achieved the task by ringing up airports near and far to figure out the best landing place for each flight.

Miraculously, this ad hoc and unstructured approach worked pretty well, especially when the controllers from different airports knew each other.

In making their recommendations the investigators noted that there was little point in making new procedures for an event that was unlikely to ever reoccur but they did note that there was value in the air traffic controllers knowing each other and that providing opportunities for them to socialise with each other might be the most valuable lesson for future unpredictable events.

For Story Students

The Setting: 5000 planes carrying a million people had to be landed immediately

The Complications: Terrorist attacks and the unprecedented grounding of the entire North American airspace

The Turning Point: Air traffic controllers around the country instinctively knew to contact each other to manage the landings

The Resolution: The airspace was safely cleared

The Point of the Story: The airspace was safely cleared

How to use this story: When talking about procedures and processes for unlikely events and how it doesn't always make sense to create new processes.
