Down river from the Naval Yard but could expose a plane to an idiot ground fire and I imagine there is lots of helo activity as well.
UPDATE: Ground stop at Reagan National Airport is for departures http://bit.ly/1eUGWul.
MSNBC reports says reason for Reagan shut down is because of helicopter traffic for Navy Yard shooting.
I seriously doubt it. A little pop gun couldn’t reach where the planes have to go. Maybe if he had a RPG.
The flight path doesn’t take planes over the Navy Yard, the problem is the subway stop at the Navy yard makes the airport only a few minutes away.
I think you’re right about it being helo related. FBI HRT is at Quantico and there are military reaction units at Davidson Airfield at Ft Belvoir. Both would approach the Navy Yard going upriver past Reagan National. They probably want to keep the airspace clear.
