Engines of the Gods

Mars' ruins hold ancient engines of power, and Guantra would use these to gain control of the solar system. But Kortha, the larger-than-life hero, will try to defeat him. And win beautiful Ilse's hand in the process, of course.

In this hi-tech 1946 view of Mars, airships apparently still have open decks and masts, and carry gunpowder in their holds. Some interesting rubber science here.
