In this alternate history novel, Nazi Germany is building Silbervogel, Eugen Sänger‘s proposed “antipodal bomber”, in an attempt to firebomb New York during WWII. Learning about the work from spy efforts, a US team led by Robert Goddard builds a counter-weapon, an American suborbital interceptor.
For a fan of the history of astronautics, this novel is a treat. While in reality Nazi Germany focused its rocketry efforts on the A-4 rocket, better known as the V-2 ballistic missile, it is not a big stretch to imagine how efforts could have gone towards Silbervogel instead. Steele mixes real people and fictional events in a very plausible “what if?” of history.
