On Monday, flights were halted at Newark Liberty International, Philadelphia International, and Teterboro airports due to radio equipment issues affecting Philadelphia’s terminal radar approach control. This disruption coincided with a Government Accountability Office (GAO) report revealing vulnerabilities in the FAA's communication systems, which are susceptible to hacking and can lead to safety risks like false flight cancellations. Senator Ron Wyden emphasized the urgent need for updated cybersecurity standards to protect national security and public safety.

Story summary
On Monday, 5,600 flights across the US were delayed or canceled after a backup fiber cable was accidentally cut by an Amtrak construction crew in New Jersey, causing significant disruptions at airports like Newark Liberty, Philadelphia International, and John F. Kennedy Airport just as world leaders arrived for the United Nations General Assembly meeting in New York. The Federal Aviation Administration (FAA) ordered ground stops to ensure airspace safety until a new circuit was made operational. Travelers are entitled to full refunds under U.S. law but not compensation since the issue was beyond airlines' control.

A congressional watchdog has warned the systems guiding US aircraft are open to interference and deception as flights into three busy airports in the country’s north east US were halted by a radio equipment problem.
asserted
flights → warn → problem
The Federal Aviation Administration (FAA) ordered a ground stop at about 10am on Monday for Newark Liberty international, Philadelphia international and Teterboro airports, saying some radio frequencies at the Philadelphia terminal radar approach control (Tracon) were affected until the early afternoon.
asserted
frequencies → order → afternoon
Arrivals and departures at Newark were delayed, and the agency has not said what caused the outage.
asserted
what → delay → outage
The disruption coincided with the publication of a government accountability office (GAO) report, which found that the FAA has yet to finish risk assessments or update security documentation covering threats from spoofing, jamming and other attacks on the radio spectrum – prompting a prominent senator to warn of a “major threat” to national security.
asserted
FAA → coincide → security
The FAA also lacks a real-time system to detect all such threats, the report said, meaning it can generally only investigate incidents after they are reported.
asserted
they → lack → incidents
Investigators warned that a hacker could send fraudulent messages, such as false cancellations of flight clearances, to aircraft, with the potential to cause delays, disrupt airspace or create safety risks.
uncertain
hacker → warn → risks
Two systems used to send text messages to aircraft predate modern cybersecurity standards and lack common protections such as encryption, according to the report.
uncertain
systems → use → report
The watchdog’s findings prompted calls for swift action.
asserted
findings → prompt → action
“The FAA’s failure to require the aviation industry to use secure communications is a major threat to US national security, to our economy and the safety of the flying public,” said Ron Wyden, the US senator for Oregon, who has long campaigned on privacy, surveillance and cyber security issues.
asserted
who → require → issues
“The FAA needs to issue new standards, as soon as possible, to protect the security of airline communications.”
The GAO made nine recommendations, including a formal risk assessment of seven of eight reviewed systems, continuous monitoring for interference, spoofing and jamming, and formal guidance on information sharing.
asserted
GAO → need → sharing
The department of transportation, replying for the FAA, agreed with all nine.
asserted
department → reply → nine
In April 2025, an outage blanked controllers’ screens for roughly 60 to 90 seconds and cut their contact with aircraft, prompting the FAA to halt departures.
asserted
outage → blank → departures
The FAA later moved the Philadelphia Tracon to a new fiber-optic link with New York on two separate paths, as part of measures to improve reliability.
asserted
FAA → move → reliability
The FAA handles more than 44,000 flights a day and about 3 million passengers, the GAO noted.
asserted
GAO → handle → flights
Wyden, who sits on the Senate intelligence committee, added: “This sobering report from [the] GAO reveals that the technology used by air traffic controllers to communicate with aircraft is incredibly insecure, can be intercepted, impersonated, and jammed, and that hackers and foreign governments can exploit these vulnerabilities to disrupt air travel and even put passengers at risk.”
asserted
hackers → sit → risk
The GAO also pointed to jamming and spoofing abroad.
asserted
GAO → point → jamming
Estonia and Finland have accused Russia of interfering with satellite navigation in their airspace, which Moscow denies.

Moscow → accuse → which
One incident last September involved a Spanish military jet carrying the country’s defense minister.
