## Executive Summary
A nationwide FAA ground stop halted US flights on November 14, with coverage pointing to an L3Harris router as the suspected cause.

## Intelligence Brief
A nationwide ground stop ordered by the Federal Aviation Administration brought US air travel to a halt on November 14, 2026, with coverage from NBC 7 San Diego and CBS News reporting on the disruption and its aftermath. The ground stop affected airports across the country, including San Diego International Airport and Baltimore/Washington International Thurgood Marshall Airport (BWI), where flights were halted before later resuming operations.


Coverage from NBC 7 San Diego centers on travelers at San Diego International Airport sharing stories of delays and detours in the wake of the ground stop. The outlet reports on passengers stranded at the airport, describing the confusion and frustration as they navigated rebooking options and uncertain timelines. Meanwhile, CBS News reports that flights have resumed at BWI following the nationwide ground stop, indicating that the FAA lifted the order and operations are returning to normal at that major East Coast hub.


The context for this disruption lies in the critical role of FAA systems in managing US airspace, where a single point of failure in communications or navigation infrastructure can cascade into a national ground stop.


What to watch next includes any official statement from the FAA on the root cause and duration of the outage, as well as whether L3Harris or the agency will disclose remediation steps to prevent recurrence. Coverage does not yet specify if the ground stop was triggered by a complete system failure or a precautionary measure, nor does it indicate whether other airports beyond San Diego and BWI experienced extended delays after the order was lifted. Congressional oversight or an NTSB inquiry could follow if the incident is classified as a significant safety event, but no such actions are mentioned in the current reporting.
