G-8, the high-flying ace pilot of World War I, was born in the front seat of a car barreling through the Holland Tunnel. His father was Robert Jasper Hogan, who had made quite a name for himself as a prolific pulp writer specializing in aviation fiction during the glamorous era now styled Between the Wars. Among practitioners of that now-lost art, this school of writing was styled Yammering Guns, after the sound of contending synchronized machine guns in furious action.

Flying a Spad warplane marked only with his cryptic code name, the invincible ace ranged the blood-soaked skies over No Man's Land, hunting the worst war criminals the Kaiser had to offer. His orders: Shoot them down in flames!
