"Be good to get back in the air again. Perhaps anti-sub patrol, eh?"

"Very likely."

They fell silent again. The car skimmed west on Highway 80, leaving the silver rocket farther behind with every mile. Where to and what next? He gave up trying to figure the Colonel's strategy. One thing he was sure of. The hard-faced man next to him knew exactly what he was doing. If it was secret agent stuff, then that's the way it had to be played.


He leaned back and thought of the task ahead—the rocket he had lived with for over a year. Now the marriage would be consummated. Every detail of the Aztec was vivid in his mind. Like the three great motors tucked triangularly between her tail fins, each a tank equipped with a flaring nozzle to feed in hot gases under pressure. He pictured the fuel tanks just forward of the engines; the way the fuels were mixed, vaporized, forced into the fireports where they would ignite and react explosively, generating the enormous volumes of flaming hot gas to drive out through the jet tubes and provide the tremendous thrust needed to boost her into the skies. Between the engines and fuel tanks was a maze of machinery—fuel lines, speed controllers, electric motors.

He let his mind rove over the rocket thinking that before many hours had passed he would need every morsel of the knowledge he had so carefully gathered. Midway where the hull tapered was a joint, the separation point between the first and second stages. The second stage had one engine fed by two tanks. The exterior of the second stage was smooth, finless, for it was designed to operate at the fringe of space where the air molecules were widely spaced; but it could be steered by small deflectors mounted in its blast stream.

The third stage was little more than a space cabin riding between the tapered nose cone and a single relatively low-thrust engine. Between the engine and tanks was a maze of turbines, pumps, meters, motors, wires. A generator provided electricity for the ship's electric and electronic equipment; this in turn was spun by a turbine driven by the explosive decomposition of hydrogen peroxide. Forward of this was the Brain, a complex guidance mechanism which monitored engine performance, kept track of speed, computed course. All that was needed was the human hand. His hand.


They traveled several hours with only occasional words, purring across the flat sandy wastes at a steady seventy. The cars boxing them in kept at a steady distance.

Crag watched the yellow headlights sweep across the sage lining the highway, giving an odd illusion of movement. Light and shadow danced in eerie patterns. The chauffeur turned onto a two-lane road heading north. Alpine Base, Crag thought. He had been stationed there several years before. Now it was reputed to be the launch site of one of the three drones slated to cross the gulfs of space. The chauffeur drove past a housing area and turned in the direction he knew the strip to be.
