Jennings looked at him in dismay. Was the man kidding him? Explain the zenith of science, the culmination of the dreams of man in twenty simple words or less! And about ten minutes to win over a man which the Pentagon had failed to win.

"Perhaps you'd like to sit here, Senator," he said courteously. "When we learned you were coming, we felt yours should be the honor. At zero time, you press this key—here. It will be your hand which sends the test ship out into space."

Apparently they were safe. The senator knew so little, he did not realize the automatic switch would close with the zero time signal, that no hand could be trusted to press the key at precisely the right time, that the senator's key was a dummy.

"Beep, ten," the signal came through.

Jennings went back over to the periscope and peered through the slit. He felt strangely surprised to see the silver column of the ship still there. The calm, the scientific detachment, the warm thrill of co-ordinated effort, all were gone. He felt as if the test flight itself was secondary to what the senator thought about it, what he would say in his progress report.

He wondered if the senator's progress report would compare in any particular with the one on the ship. That was a chart, representing as far as they could tell, the minimum and maximum tolerances of human life. If the multiple needles, tracing their continuous lines, went over the black boundaries of tolerances, human beings would die at that point. Such a progress report, showing the life-sustaining conditions at each point throughout the ship's flight, would have some meaning. He wondered what meaning the senator's progress report would have.

He felt himself being pushed aside from the periscope. There was no ungentleness in the push, simply the determined pressure of an arrogant man who was accustomed to being in the center of things, and thinking nothing of shoving to get there. The senator gave him the briefest of explanatory looks, and placed his own eye at the periscope slit.

"Beep, nine," the signal sounded.

"So that's what represents two billion dollars," the senator said contemptuously. "That little sliver of metal."

"The two billion dollar atomic bomb was even smaller," Jennings said quietly.
