 What is Rolf's new plan when he spots the rocket?
[Transcriber's Note: This etext was produced from Planet Stories Winter 1944. Old Garmon Nash's harsh voice snapped like a thunderclap in the cramped rocket flyer's cabin. Sisko Rolf's stocky body was a blur of motion as he cut the rocket jets, doused the twin searchlights, and switched over to the audio beams that served so well on the surface when blind flying was in order. But here in the cavern world, thirty-seventh in the linked series of vast caves that underlie the waterless wastes of Mars, the reflected waves of sound were of little value. "Trapped us neatly," Rolf said through clenched teeth. "Tolled into their underground hideout by that water-runner we tried to capture. We can't escape, that's certain. They know these caverns better than.... That was old Garmon Nash, his fellow patrolman aboard the Planet Patrol ship as he swung the deadly slimness of his rocket blast's barrel around to center on the fiery jets that betrayed the approaching outlaw flyers. Three times he fired the gun, the rocket projectiles blasting off with their invisible preliminary jets of gas, and three times an enemy craft flared up into an intolerable torch of flame before they realized the patrol ship had fired upon them. Then a barrage of enemy rocket shells exploded into life above and before them. Rolf swung the lax controls over hard as the bursts of fire revealed a looming barrier of stone dead ahead, and then he felt the tough skin of the flyer crumple inward. Down plunged the battered ship, downward ever downward. Somehow Rolf found the strength to wrap his fingers around the control levers and snap on a quick burst from the landing rockets. Their mad speed checked momentarily, but the nose of the vertically plunging ship dissolved into an inferno of flame. The ship struck; split open like a rotten squash, and Rolf felt himself being flung far outward through thick blackness. There was light in the narrow pit in which he found himself, light and heat from the yet-glowing debris of the rocket flyer.
 He'll be able to distribute water to Mar's colonies, and get out with Tanner and the girl.
 Now that he knows the location of the water, he'll be able to return to grab it for himself.  He'll have a way out of the caverns at last, be able to escape.  He can escape the fighting and leave Tanner and the girl behind.  He'll be able to distribute water to Mar's colonies, and get out with Tanner and the girl.
