Washington Monument (with Plane) at Sunset
Can't be absolutely sure about the plane in this shot. It was clear from the start that it's either a Boeing 737 (unlikely because of the fuselage line) or an Airbus 319 or 320. Given that the plane is on approach to Washington Reagan National (DCA) and that the dominant carrier into DCA is US Airways, I concluded that this is probably an Airbus 319. In editing mode, I zoomed deeply into the image and bumped up the exposure control to reveal winglets on the port wing. Since the winglets don't have the upsweep of the Boeing 737-800 or 900 series, it's definitely an Airbus and probably a 319.
