From a Pentagon news story about the departure ceremony for George Bush at Andrews Air Force Base --
The crowd roared as the former president and vice president made their dramatic entrance into the hangar. The rousing sounds of the “Air Force One” movie theme rung out as the huge hangar slowly opened, revealing the huge blue-and-white presidential aircraft glistening in the sunlight.
As the article later quietly explains, Bush's days with an actual AF1 were done by that point.
UPDATE: Bush wore an Air Force One jacket on the final flight.
