There are many reasons why an airport might ground planes. For example, in May 2025, Atlanta's Hartsfield-Jackson Airport, America's busiest airport, grounded all flights due to an equipment outage. The Federal Aviation Administration (FAA) issued the ground stop, delaying at least 410 flights and cancelling five by 1 pm. Similarly, the FAA issued a brief ground stop at Newark Liberty International Airport due to an audio issue at the ATC facility. These decisions to ground planes are made to ensure the safety of passengers, crew, and the general public.

What You'll Learn
Equipment failure
Air traffic control equipment failures can also lead to planes being grounded. For example, in April and May 2025, Newark Liberty International Airport experienced several radar and communication outages. These outages prevented air traffic controllers from seeing or communicating with aircraft, resulting in significant delays and cancellations. In some cases, planes were instructed to maintain an altitude of 3,000 feet or higher to ensure safe operations.

Radar outage
The impact of such outages on air traffic control operations cannot be overstated. Controllers rely on radar systems to track and manage aircraft movements, and when these systems fail, the risk of collisions increases. In the case of the Newark outage, air traffic controllers were left unable to communicate with pilots, a situation described as "'everybody's worst nightmare'" by a retired controller.
To manage these situations, each air traffic control facility has an "operational emergency plan" that outlines procedures to follow during cataclysmic events, including power outages. While these systems have redundancies, sometimes failures can occur at a basic infrastructure level, eliminating these backup measures. In the case of the Philadelphia TRACON facility, controllers can activate an "emergency service" button, which provides a backup scope displaying critical flight information such as aircraft positions, altitudes, and speeds.
However, despite these contingency measures, radar outages can still have far-reaching consequences. The April 2025 radar outage at Newark resulted in hundreds of flight cancellations and delays, with the Federal Aviation Administration (FAA) slowing down traffic to prioritize safety. Additionally, several controllers were so distressed by the incident that they took trauma leave, further exacerbating staffing shortages and contributing to ongoing delays.
The root causes of radar outages can vary. In the case of Newark, outdated infrastructure and staffing shortages have been identified as key factors. Transportation Secretary Sean Duffy has announced a multibillion-dollar plan to replace the nation's aging air traffic control system, addressing the shortcomings of outdated technology and infrastructure. The plan includes the installation of 4,600 new high-speed connections and the replacement of 618 radars across the country.

Air traffic control issues
Air traffic control (ATC) services play a critical role in ensuring the safe and efficient movement of aircraft and vehicles within an airport's taxiways, runways, and surrounding airspace. However, issues within ATC operations can lead to significant disruptions, including grounding planes and causing extensive delays.
One of the primary issues within ATC is the outdated technology and equipment used in some regions, particularly in the United States. The Federal Aviation Administration (FAA) in the US has been criticised for its "antiquated" air traffic control system, which relies on archaic methods such as paper flight strips and ground-based radar systems. This outdated equipment has been blamed for several incidents, including a collision between a helicopter and a passenger jet, and a FedEx plane nearly landing on top of another aircraft due to low visibility.
In contrast, overseas controllers in countries like Canada utilise advanced technology such as sleek computer screens and high-resolution cameras to monitor planes, allowing for more efficient and accurate control.
Another critical issue within ATC is the shortage of controllers and staff. This problem is prevalent in the US, where thousands of vacant controller positions remain unfilled. The shortage has been exacerbated by incidents causing trauma to controllers, such as the loss of communication with aircraft at Newark Liberty International Airport, leading to several controllers taking extended leave.
The combination of outdated technology and staff shortages has resulted in significant disruptions to air travel, with grounded planes, delayed flights, and frustrated passengers.
To address these issues, there have been calls for independent corporations to take over ATC services, similar to the successful model implemented in Canada, where funding through user fees allows for efficient modernisation. Additionally, there is a push for the adoption of new technologies, such as satellite guidance systems and digital standards, to improve the efficiency and accuracy of ATC operations.

Safety concerns
One of the primary reasons for grounding planes is equipment failure or technical issues. This can include radar and telecommunication outages, as seen in the case of Newark Liberty International Airport, where radar screens went dark, causing communication loss with aircraft. Such incidents can be extremely dangerous, as they prevent air traffic controllers from effectively monitoring and guiding flights. In such situations, a ground stop is a necessary safety precaution to prevent potential mid-air disasters.
Airports may also ground planes due to adverse weather conditions, such as heavy fog, snow, or storms, which can impair visibility and make flying unsafe. Additionally, wildlife hazards, such as bird strikes, can be a concern, leading to temporary grounding until the issue is resolved.
Another critical safety concern is the potential for collisions and accidents. In the tragic case of the mid-air collision at Reagan National Airport, which resulted in numerous fatalities, a ground stop was likely implemented to prevent further incidents and ensure the safety of other aircraft in the area.
Furthermore, safety audits and investigations following a significant incident or accident can lead to grounding. For example, after a serious incident, an airport may voluntarily ground flights to conduct safety inspections and reviews, ensuring that all procedures and equipment are functioning correctly and meeting safety standards.
Finally, safety concerns can extend to issues with aircraft themselves. Airports may ground specific aircraft models if a mechanical or design flaw is identified, as seen with the Boeing 737 MAX groundings following two tragic crashes. In such cases, grounding is a precautionary measure to safeguard passengers and crew until necessary modifications or repairs are made.

Traumatic events
There are many reasons why an airport might ground planes, some of which can be traumatic events. Traumatic events can include deadly mid-air collisions, such as the one that occurred at Reagan National Airport in January 2025, resulting in 67 fatalities. Following this incident, air traffic controllers at Newark Airport experienced a separate traumatic event when radar screens went dark, causing a brief halt to all departures. This radar outage lasted for about 60 to 90 seconds, during which controllers were unable to communicate with aircraft.
In the aftermath of these incidents, air traffic controllers at Newark went on medical leave, as they are entitled to do so for at least 45 days, with a doctor's evaluation required before returning to work. The Federal Aviation Administration (FAA) also issued a brief 45-minute ground stop at Newark due to an audio issue, which was resolved by switching to a backup system.
These events highlight the potential for traumatic experiences within the aviation industry, particularly for air traffic controllers who are responsible for ensuring the safe and efficient flow of air traffic. The impact of such incidents can be significant, leading to medical leave and increased awareness of the need for improved funding and resources for air traffic control systems.
