Here's the link re: the actual wording of the restricted airspace over DC. AOPA DC NOTAM
I bet they are pilots no more. If it was all "innocent" then they are too stupid to remain pilots. It could have been more sinister -- they simply could have been on a mission to "test the waters."
I was flying with my brother in his Cessna Citation on our way to Cabo and the lcd screen in the instrument panel showed the boundaries of these areas extremely clearly. Coupled to gps and a picture of our plane over the map there is no way we could encroach more than a few feet into the no-fly areas unless we suddenly went blind. the autopilot was even programmed to go around them.
How fortunate we are that you are not in charge of anything to do with Homeland Security and the other involved agencies.
