DC-area flights grounded again after odor at Warrenton TRACON

The FAA halted traffic at Reagan National (DCA), Dulles (IAD), and BWI, along with Charlottesville (CHO) and Richmond (RIC) area airports, after an overheated battery in an IT cabinet at the Potomac Consolidated TRACON facility in Warrenton, Va., produced a strong odor. The ground stop was lifted around 7:30 p.m. Friday. No injuries were reported. This marks the second odor-related disruption at the same facility in weeks and comes as the region’s travel system weathered ongoing stresses from a partial government shutdown affecting TSA staffing.
