A ground stop was issued for all three major airports serving the Washington, D.C. area on Friday afternoon due to a strong chemical odor at an air traffic control service center in Potomac.
Ronald Reagan Washington National Airport, Washington Dulles International Airport and Baltimore/Washington International Airport were all affected.
Officials said the disruption was linked to a ‘strong chemical smell’ detected at the Potomac Consolidated Terminal Radar Approach Control facility, commonly known as Potomac TRACON, which oversees air traffic in the region.
