"We've made it," Crag exulted. "We're on that old moon trajectory." The Chiefs face reflected his wonder. Crag studied his instruments. Speed slightly over 22,300 miles per hour. The radar altimeter showed the Aztec slightly more than one thousand miles above the earth's surface. He hesitated, then cut off the third stage engine. The fuel gauge indicated a bare few gallons left. This small amount, he knew, represented error in the precise computations of escape. Well, the extra weight was negligible. At the same time, they couldn't afford added acceleration. He became aware that the last vestige of weight had vanished. He moved his hand. No effort. No effort at all. Space, he thought, the first successful manned space ship.
Elation swept him. He, Adam Crag, was in space. Not just the top of the atmosphere but absolute space—the big vacuum that surrounded the world. This had been the aim ... the dream ... the goal. And so quick!
He flicked his mind back. It seemed almost no time at all since the Germans had electrified the world with the V-2, a primitive rocket that scarcely reached seventy miles above the earth, creeping at a mere 3,000 miles per hour.
The Americans had strapped a second stage to the German prototype, creating the two-stage V-2-Wac Corporal and sending it 250 miles into the tall blue at speeds better than 5,000 miles per hour. It had been a battle even then, he thought, remembering the dark day the Russians beat the West with Sputnik I ... seemingly demolished it with Sputnik II—until the U. S. Army came through with Explorer I. That had been the real beginning. IRBM's and ICBM's had been born. Missiles and counter-missiles. Dogs, monkeys and mice had ridden the fringes of space. But never man.
A deep sense of satisfaction flooded him. The Aztec had been the first. The Aztec under Commander Adam Crag. The full sense of the accomplishment was just beginning to strike him. We've beaten the enemy, he thought. We've won. It had been a grim battle waged on a technological front; a battle between nations in which, ironically, each victory by either side took mankind a step nearer emancipation from the world. Man could look forward now, to a bright shiny path leading to the stars. This was the final step. The Big Step. The step that would tie together two worlds. In a few short days the Aztec would reach her lonely destination, Arzachel, a bleak spot in the universe. Adam Crag, the Man in the Moon. He hoped. He turned toward the others, trying to wipe the smug look from his face.
The oddity of weightlessness was totally unlike anything he had expected despite the fact its symptoms had been carefully explained during the indoctrination program. He was sitting in the pilot's seat, yet he wasn't. He felt no sense of pressure against the seat, or against anything else, for that matter. It was, he thought, like sitting on air, as light as a mote of dust drifting in a breeze. Sure, he'd experienced weightlessness before, when pushing a research stratojet through a high-speed trajectory to counter the pull of gravity, for example. But those occasions had lasted only brief moments. He moved his hand experimentally upward—a move that ended like the strike of a snake. Yeah, it was going to take some doing to learn control of his movements. He looked at Prochaska. The Chief was feeding data to Alpine Base. He finished and grinned broadly at Crag. His eyes were elated.
"Sort of startling, isn't it?"
"Amen," Crag agreed. "I'm almost afraid to loosen my harnessing.
"Alpine says we're right on the button—schedule, course and speed. There's a gal operator on now."
"That's good. That means we're back to routine." Crag loosened his harnesses and twisted around in his seat. Larkwell was moving his hands experimentally. He saw Crag and grinned foolishly. Nagel looked ill. His face was pinched, bloodless, his eyes red-rimmed. He caught Crag's look and nodded, without expression.
