You can't even get up to take a pee 30 minutes to/from Reagan National. Air Marshals on all flights.

I don't think there are any int'l flights at National, because the runways aren't long enough.

Flight attendants and crews all know each other. A strange pilot would be red flag time.

"A strange pilot would be red flag time."

A mole would by definition not be a strange pilot, but someone who was assumed to be legit, someone who had gone through the normal training. Al Quaeda bides its time, and will prepare for years to pull off something big. As for not being allowed to take a pee within 30 minutes of DC, I don't expect terrorists to follow the rules on that or anything else. :-)
