I doubt very much that this lunatic would be able to fly a plane through a window while he is half a mile away, and after it crashed, be able to activate a detonator. Totally ridiculous.
What is ridiculous is how he could be within half a mile in any direction of the Capitol where he'd have enough open space to take either of those off yet still be inconspicuous enough to not draw attention. You can't fart within 100 yards of anything down there without someone taking notice.
