Jet Power #1

This anthology issue contains two science fiction stories. "Jet Power" follows a pilot navigating a turbulent underground passage with a gravitation device, racing against torrent river waters and giant engines to escape a collapsing hangar before reaching the river. "Space Ace" is set three hundred years in the future on a colonized Mars, where a mysterious adventurer called Space Ace battles desert-dwelling creatures and contends with a malfunctioning spacecraft while combating atomic-powered threats in the Syrtis Major Basin.
