Huge gray warships used to be the primary way the United States showed its flag around the world. But there was only one problem with that: such flag-waving was limited to seaports, and the vessels’ bristling guns carried a decidedly military message.

Its gleaming fuselage, with its white and light-blue livery, declares the American chief executive is in town, tending to the nation’s business.

Unlike warships, it can deliver the President to any city with a decent airport, at home or overseas, inland or otherwise.
