Reagan National Airport is in between two overlapping No Fly Zones so pilots have to watch out for the Pentagon and CIA headquarters . And on takeoff , pilots must ascend quickly and sharply turn left so they do n't fly over the White House . After the attacks of September 11 , 2001 , security forces strongly enforce these rules . Reagan National has extra security precautions required by the Washington Air Defense Identification Zone that have been in place since the airport began operations
