Space War #16

A man named Henry carefully plans a spaceship construction site for Earth 687, concealing food in his briefcase until the proper moment. When the ship blasts off, Henry's body is discovered inside, revealing his dream of space travel has become reality. As the ship encounters various hostile alien worlds including one with poisonous gases, monstrous creatures, and a giant serpent, a Cruiser Group led by Commodore Biddle's flagship pursues the vessel through deep space toward the target area where the original ship was last sighted.
