An evacuation at Federal Aviation Administration air traffic control center located in Northern Virginia is delaying flights at Washington, D.C., area airports.
“Local fire officials directed the FAA to evacuate the Washington Center in Leesburg, VA at about 6:40 pm after fumes from construction work permeated the control room,” the FAA said in a statement Monday evening. “The center handles high altitude flights over the area. The facility stopped accepting new flights and handed off airborne flights to other air traffic control facilities for safe handling. We are actively working to fully ventilate the facility. We will update the statement when we get new information.”
The FAA, shortly after 9pm Monday, said it cleared air traffic controllers to reoccupy the Washington Center and expected operations to resume soon.
