Clarence Budington Kelland, The Highflyers
“ He was flying on a level with Cantor’s machine, approaching it from the rear. Hildegarde saw the blue shape of a revolver in Potter’s hand and bent forward, tense, breathless for the event.Cantor, unconscious that he did not occupy the heavens alone, sped onward with singleness of purpose. He was unaware of danger, unconscious of near-flying menace. Potter did not want it so. He could not attack a man, an unconscious man, from behind. What he wanted was combat, man to man conflict. Even a spy bent on treacherous mission of destruction he could not destroy without warning. ”
