An Air Force pilot rode his powerful, deadly jet-fighter across the desert country, thinking of the wife and children waiting for him in Los Angeles. Suddenly, he tensed, staring over the side. Far below, a black shape was outlined against the gray earth. Quickly, the pilot radioed his flight h.q. and fired his guns, blasting their muzzle-covers away. Then he peeled over into a dive and went screaming downward. The black shape appeared on his sights, his thumb pressed the fire-button--no time to set up for auto-fire-- And then, the black shape was gone! The wind stopped screaming around the little ship as Smitty cut its gravitors back in, halting its helpless plunge. He pointed its needle-nose up the black maw of a deep canyon and glanced upward, grinning as he thought what must be going through that jet jockey's mind. _Which way'd he go?_ Just let 'em try following a "spaceship" through one of these twisting canyons! At a jet-fighter's thousand-mile-an-hour combat speed, just let 'em try! But, as Morrow discovered, a heliocopter could follow anywhere. It wasn't when he and Gwyn drove into Stockton to get married, but later, when they were playing follow-the-leader in silvery wonderland of clouds under a full moon. He and Gwyn wore gravitor-units strapped to their backs, with the harness incorporated into a swim-suit attire, without helmets or any other garments. It was a warm summer night filled with cool breeze that caressed their skin as they circled and skimmed over and around the bright masses of cloud. A civilian pilot riding his little ram-jet heliocopter southward toward 'Frisco saw them gliding around the clouds at approximately the same moment Morrow caught sight of him. The 'copter gave chase. Morrow and Gwyn parted, trying to confuse the pilot, but the 'copter swung on its whirling blades and went after Gwyn. Its speed was greater than hers and it was rapidly overtaking her--the pilot jockeying it into position so its blades would strike her. Apparently, the pilot had a morbid sense of humor. Seeing this, Morrow swung back, intercepted the chase, and swooped low under the 'copter, trying to unnerve the pilot. But the pilot merely waved at him and laughed, shouting something about "_Gonna get one of you, anyway!_" that Morrow barely heard. He circled and dived at the 'copter again, fumbling at his belt. This time, he pulled up to the side of the 'copter's teardrop cabin, stopping himself by slamming both feet against the cabin. Startled, the pilot jerked the controls and the 'copter dipped its blades at Morrow. He had just enough time before cutting his gravitor and plunging free to fire his flash-bulb pistol directly into the pilot's face.
