WUSA9 shared:
Emergency vehicles could be seen parked near a United flight, apparently the only plane on the tarmac. WUSA9 is working to learn more information about that flight.
Flights had also been grounded on Oct. 29, when the FAA told WUSA9 that “military activities” had delayed flights. Similar to Tuesday, the FAA’s National Airspace System Status had said the ground stop was issued “due to security.”
Other area airports, such as Washington Dulles (IAD) and Baltimore / Washington (BWI), did not appear to be impacted and had a regular flight schedule on Tuesday afternoon.

A security emergency was issued at Ronald Reagan Washington National Airport (DCA) at 11:30am ET, impacting more than 800 flights.
Travelers stranded on the runway reported a bomb threat on a United flight that landed from Houston, which was quickly surrounded by emergency vehicles.
