And with that, he had gestured to Dirk and stepped back. The silence in the training ship had been absolute. The other thirteen in the class stared at the recipient of this signal honor. Who but the son of the commandant would be trusted to land a ship on his first training flight? Who but the heir to the space mantle of Commandant Jemson.

Dirk remembered the sticky perspiration that had drenched his uniform as he had stared in disbelief at the beaming Petley. He had stammered some excuse, but Petley had smiled and firmly insisted. This was no time to be modest.

Dirk had closed his eyes, moved to the controls. Through the visi-shield, the grey orb of Deimos rushed toward him. The black maw of space was a swirling, twisting, rotating nightmare that blurred up at him.

In the background, Ensign Petley had murmured explanations to the watchers. Closer and closer whirled Deimos. Dirk's hands had faltered over the degravitator. Somehow, the movement of the universe had communicated itself to him. His mind, his heart, his stomach all swam in a whirlpool of black motion.

"Now, Dirk!" Petley's voice was sharp. "Now! Show the class!"

The eyes had been on him—the urgency in the voice had been great—but the hypnotic spinning of Deimos in the visi-shield was irresistible. With a little sigh, Dirk had blacked out.

There had been very little said, naturally. Petley had broken the rules in turning a ship over to a boot, in the first place; and one of the other trainees had saved them by seizing the controls at the crucial moment and decelerating. Dirk had asked to be transferred to another class, and his request was granted. He was, after all, the Commandant's son and allowances must be made.

Enough allowances were made to permit him to graduate from the strato-school. He was a great theorist, his instructors agreed. Perhaps he lacked a little of his father's daring and drive, but he had the same comprehension, the same inter-stellar grasp.

And after graduation, nothing sensational. A little routine work between Mars and Luna—work which permitted him to stay in the navigator's cell—away from the visi-shield—away from the twisting whirlpool of space.

For, after all, promotions must not come too rapidly. He was the son of a famous man and sons of famous men are closely observed by the Universe. When he rose, it must not be the result of family, but because he was well qualified and experienced.
