Richard Knight soars into darker, wilder skies. In Volume 4 of The Complete Adventures of Richard Knight, Donald E. Keyhoe-later famed for his Philip Strange tales and his pioneering UFO work-pushes his daredevil ace farther into pulp spectacle. Across four blistering yarns, Knight meets sabotage and mad science, trading cannon bursts for heart-stopping escapes and cinematic dogfights. Fast, relentless, and vividly theatrical, these tales showcase the high-altitude thrills that made Flying Aces a proving ground for pulp adventure. This volume collects the next four Richard Knight stories, restored to their original, uncut urgency.
