On the night of March 13, 2026, a pungent odor associated with a chemical scare led local officials across its borders. In response, the Federal Aviation Administration (FAA) instituted a ground stop at four major airports in Washington, D.C., Baltimore, and Richmond, Virginia. The snoozing impacted two major airports, Ronald Reagan Washington National Airport and Washington Dulles International Airport. Furthermore, Baltimore-Washington International Airport and Richmond International Airport plunged into chaos.
The ground stop was enacted because the odor was blocking air traffic controllers from doing their job safely. FAA Secretary Sean Duffy proudly proclaimed the decision on social media. He announced that all scheduled flights to/from the affected airports would be stopped for more than an hour. The direct result was that air traffic was completely halted in the midst of one of the busiest travel windows coming into the weekend on Friday evening.
Around 7 p.m. Eastern Time, flights began leaving from the airports. A ground stop was still in place as planes launched into the air. Flight delays rocketed to almost two hours. This led to widespread chaos at many of the country’s largest and busiest airports. News articles indicated that delays affected up to a quarter to a third of all flights. These disruptions were felt at the four airports involved in the incident.
In response to the extraordinary circumstances, FAA issued a sweeping statement. They did not respond with any information on what caused the chemical odor issue or how it specifically impacted air traffic controllers. A representative from the agency did not return repeated requests for comment about how the odor impacted operations.
This incident further highlights the difficulty airport authorities and air traffic control go through in reacting to safety threats that arise unexpectedly. Now that operations were restored, travel was still disrupted with travelers urged to check with their airlines for rebooked flights and delays.
