The Federal Aviation Administration (FAA) said the odor impacted some controllers and prompted ground stops at Baltimore-Washington International Thurgood Marshall (BWI), Ronald Reagan Washington National (DCA) and Washington Dulles International (IAD).

The ground stops produced extensive delays and wider regional disruption: Dulles departures were reported up to 90 minutes or more, and several outlets said the ground stops extended to Richmond and other airports served by the same TRACON.

FAA alerts and airline reports estimated the stoppage would last into the evening, with many outlets quoting an expected lift time around 8 p.m. and passengers describing congested gates and long waits.

The Potomac Consolidated TRACON — the regional Terminal Radar Approach Control facility in Warrenton — manages a large swath of Mid-Atlantic airspace for the Baltimore-Washington and Richmond–Charlottesville corridors, including Andrews, Reagan, Dulles, BWI and Richmond; several outlets emphasized how an outage there ripples across the region’s flights.

The Baltimore Banner and TravelPirates noted the TRACON was built by Lockheed Martin in 2002 to handle high volumes of traffic, underscoring why disruption at the site has wide effects.

Officials and outlets provided differing descriptions as they investigated: the FAA framed the immediate cause as a strong odor at Potomac TRACON, while some reporting also cited an equipment outage as the operational cause.

Transportation Secretary Sean Duffy posted updates saying FAA teams were probing the odor and working to address the source, and some outlets reported the agency began moving controllers to a backup training facility to keep some flights moving.

Passengers and airports felt immediate disruption: reports described crowded gates, travelers sprawled on floors, and local airports buzzing with discontent as departures were delayed or diverted.
