Please add the following supplement to your flight instruction manual regarding the navigation of your aircraft near Washington DC:
If you can see the Capitol Dome, fly in the opposite direction AWAY from downtown DC.
If you see the Capitol in the distance, do not fly closer to it.
If you see the Washington Monument in the distance, do not fly closer to it.
If you see the White House in the distance, do not fly closer to it.
Even without instruments, the preceding supplement should be adequate for ensuring your safety and precluding the need to evacuate the seat of power in the United States.
Happy Flying! Morons.
