WASHINGTON – In a significant disruption to air travel in the Mid-Atlantic region, airports serving Washington, D.C., Baltimore, and parts of Virginia experienced a brief halt in flight operations on Friday evening. This interruption was prompted by reports of a strong chemical smell at the Potomac Terminal Radar Approach Control (TRACON), the facility responsible for managing air traffic in the area.
The Federal Aviation Administration (FAA) confirmed that the ground stop affected major airports including Ronald Reagan Washington National Airport, Washington Dulles International Airport, and Baltimore-Washington International Airport, among others. According to a spokesperson from the Department of Transportation, the decision to halt all flights was made as a precautionary measure while authorities investigated the source of the odor.
FAA spokeswoman Kristen Alsop reported that air traffic controllers were gradually returning to work as the situation was assessed. Normal flight operations were expected to resume shortly thereafter. Baltimore-Washington International Airport noted on the social media platform X that while the FAA’s ground stop had been lifted, travelers should anticipate some residual delays as the air traffic system normalized.
In light of the disruptions, travelers were advised to remain vigilant. New York City Emergency Management cautioned passengers heading to Washington that they might encounter significant delays due to the ground stop. The agency recommended that travelers check directly with their airlines for the latest updates regarding their flights, as cancellations and departure delays could occur.
This incident marked the second time in a month that flights in the region were suspended due to a chemical smell emanating from the Potomac TRACON facility. Earlier in the month, a similar situation unfolded, leading to a temporary ground stop that lasted approximately one hour. Transportation Secretary Sean Duffy indicated that the previous odor was traced to a circuit issue, and operations were resumed once firefighters confirmed there was no threat to the safety of air traffic controllers.
As airports and authorities work to ensure the safety and efficiency of air travel, these recent events underscore the importance of prompt responses to potential hazards in the aviation industry. Travelers are encouraged to stay informed and prepared for any changes to their travel plans.
