Raiders Invisible illustrated — D.W. Hall

he muffled, helmeted figure of a pilot climbed down the spider ladder, nestled into the foremost scout's cockpit and pressed the starting button. The motor spat out a wisp of smoke, then burst into its full-throated roar: the automatic clamp above loosened: the scout dropped plummet-like, bobbed to the flagship below, straightened out and zoomed six thousand feet up into the morning blue, where it hovered for a few moments like an eagle on taut wings. Lieutenant Christopher Travers, the pilot, glanced around.Behind and below him was spread a magnificent panorama. Across the plate of scintillating glass that was the sea moved rows of toy ships, tipped by the gleaming, one-fifth-mile long shape of a dirigible, of whose three scout planes Chris's was the leader.

The eyes of the whole world were on that array of America's ocean might-the eyes of one foreign nation in particular. Washington knew of the policies of that nation, and wished to impress upon is the hopelessness of them. More than a game, this concentration of sea and air-borne fighting power was a gesture for the continued peace of the world-a gesture strong with the hint of steel.Chris Travers was vaguely aware, through the rumors of the mess-room, of the double meaning of the game he was playing his part in, but this morning he didn't give a single
