In the novel, Caiden introduced the character Steve Austin the astronaut and test pilot who had been horribly maimed in a testing crash. This novel later inspired the long running television series The Six Millon Dollar Man.

Caiden was best known for his historical work on military aviation, including Samurai! a biography of Japanese ace Saburo Sakai and Thunderbolt! a biography of American ace and Medal of Honor winner Robert S. Johnson.
