Now if I recall correctly, All the tail numbers on Presidential Aircraft were variations of "1600" Pennsylvania Avenue, and the actual address of the White House in Washington D.C. It is something of an honored service amongst the US Air Force Crewmen to get a gig maintaining the President's aircraft in topflight condition. So, I couldn't resist taking a Snap of the aircraft's tail number as I deplaned. This particular version of AF1 is on loan from the Air Force as well.
