Nationwide ground stop lifted after four-hour delay

The US Federal Aviation Administration has lifted a nationwide ground stop that lasted over four hours, its longest since the 2001 terrorist attacks. The stoppage was caused by a communication issue affecting all air traffic control centers in the country.

According to Homeland Security Secretary Markwayne Mullin, there is no evidence of a cyber-attack and everyone involved is safe. Mullin's statement comes as the FAA attributed the issue to "extraordinary circumstances" that required an immediate response.

The ground stop had significant consequences for air travel, with over 8,500 flights delayed and nearly 8,000 canceled on Friday alone, according to data from FlightAware. The FAA initially announced the halt at 15:54 EST, stating that all flights departing within the US would be grounded until further notice.

More than 3,500 planes were airborne when the ground stop was implemented, with some diverted to alternative airports and others continuing to their destinations despite the ban on takeoffs in the US.

The ripple effect of the ground stop is expected to last for several days, according to US Transportation Secretary Sean Duffy. This means that travelers can anticipate continued disruptions in their plans over the coming days. Duffy's words reflect the severity of the situation.

Tens of thousands of people are currently stranded in airports across the country, many without a clear plan for where they will spend the night. The lack of information has added to the stress and uncertainty faced by these passengers. Some have expressed concern about their immediate living arrangements.

Delta Air Lines and United Airlines have announced that they will resume operations. This is a positive development for those affected by the ground stop. However, not all airlines are ready to return to normal service yet. American Airlines has stated its intention to operate as many remaining flights as possible this evening.

JetBlue has also indicated that it will resume flights on Saturday morning. Meanwhile, British Airways advises passengers to check their flight status before heading to the airport, but still encourages them to travel as planned.

Passengers who experience long delays due to air traffic control issues may be entitled to compensation under certain circumstances. This is because airlines are liable for damages if the cause of the delay falls within their control, such as a mechanical fault with the aircraft or pilot illness.

However, passengers do not have the same rights when it comes to air traffic control problems. In these cases, airlines are exempt from providing financial compensation to affected travelers. But there is still some protection in place for passengers under US federal and country-specific laws.

Under the FAA Reauthorization Act of 2024, airlines must offer alternative travel or a full refund to passengers whose flights have been canceled or significantly delayed. A flight is considered significantly delayed if it takes three hours or more for domestic routes and six hours or more for international flights.

Airlines operating in the UK are required by law to provide assistance to passengers when flights are delayed or cancelled due to various reasons. This includes providing a reasonable amount of food and drink, often through vouchers that can be redeemed at airport shops or restaurants.

Passengers also have access to means of communication, which may involve refunding the cost of phone calls made while waiting for their flight to resume. In some cases, airlines may offer free accommodation for overnight stays if the next day's flight is still delayed. If an airline fails to provide assistance, passengers can organize it themselves and claim reimbursement later.

According to Duffy, a legacy air traffic control system was responsible for the prolonged ground stop. The system, which relies on analogue telecommunications, became overwhelmed with data and eventually crashed, disrupting communications and radar operations. In his opinion, this outdated technology requires a complete overhaul at an estimated cost of $50 billion.

Homeland Security Secretary Markwayne Mullin has dismissed speculation about cyber-attacks being responsible for the ground stop, stating there is "zero evidence" to support such claims. He also ruled out any connection between the incident and a separate global Microsoft outage that occurred on Thursday.

A review of the incident has revealed that introducing new technology into an outdated air traffic control system caused a significant overload.

The public's safety was never at risk during the nationwide stoppage, according to both cabinet secretaries involved in investigating the matter.

This latest ground stop is only the second such event since the aftermath of the 9/11 plane hijackings.

The incident has been compared by experts to a similar US grounding that occurred in 2023 due to a failure in the Notice to Air Missions system.
