The Nautilus did not land, nor did she tie up to a space station. Instead her speed was reduced as she approached the planet so that she fell into a 2-hour, pole-to-pole parking orbit only a few hundred miles outside the silvery cloud blanket. The Venus colonies were too young, too poor, to afford the luxury of a great orbiting station in space, but a fast pole-to-pole parking orbit caused a ship to pass over every part of the spinning globe, an “orange slice” at each pass—like winding string on a ball.
A shuttle ship up from the surface could leave any spot on Venus, rendezvous with the ship in orbit, then land on its port of departure or on any other point having expended a theoretical minimum of fuel. As soon as the Nautilus had parked such shuttles began to swarm up to her. They were more airplane than spaceship, for, although each was sealed and pressurized to operate outside the atmosphere while making contact with orbiting spaceships, each was winged and was powered with ramjet atmosphere engines as well as with rocket jets. Like frogs, they were adapted to two media.
A shuttle would be launched to catapult from the surface, her ramjets would take hold and she would climb on her wings, reaching in the thin, cold heights of the upper stratosphere speeds in excess of three thousand miles an hour. There, as her ramjets failed for want of air, her rocket jets would take over and kick her forward to orbiting speed of around twelve thousand miles an hour and permit her to match in with a spaceship.
A nice maneuver! It required both precise mathematical calculation of times, orbits, fuel expenditure, and upper air weather and piloting virtuosity beyond mathematical calculation—but it saved pennies. Once the shuttle was loaded at the spaceship it was necessary only to nudge it with its rockets against the orbital direction whereupon the shuttle would drop into a lower orbit which would eventually intersect the atmosphere and let the pilot take a free ride back to the surface, glider fashion, killing his terrible speed by dipping ever lower into the thickening air. Here again the pilot must be an artist, for he must both kill his momentum and conserve it so that it would take him where he wanted to go. A shuttle, which landed out in the bush, a thousand miles from a port, would never make another trip, even if pilot and passengers walked away from the landing.
Don went down in the Cyrus Buchanan, a trim little craft of hardly three hundred feet wingspread. From a port Don watched her being warped in to match air locks and noticed that the triple globes of Interplanet Lines had been hastily and inadequately painted out on her nose and over had been stenciled: MIDDLE GUARD-VENUS REPUBLIC. This defaced insignia brought the rebellion home to him almost more than had the bombing of Circum-Terra. Interplanet was strong as government—some said it was the government. Now hardy rebels had dared to expropriate ships of the great transport trust, paint out the proud triple globes.
Don felt the winds of history blowing coldly around his ears. McMasters was right; he now believed that no ship would run from here to Mars.
When his turn came he pulled himself along through the air locks and into the Cyrus Buchanan. The craft’s steward was still in the uniform of Interplanet but the company’s insignia had been removed and chevrons had been sewed to his sleeves. With this change had come a change in manner; he handled the passengers efficiently but without the paid deference of the semi-servant.
The trip down was long, tedious, and hot, as an atmosphere-braking series always is. More than an hour after touch off the airfoils first took hold; shortly Don and the other passengers felt almost full weight pressing them into the cushions, then the pilot lifted her as he decided his ship was growing too hot, let her ride out and upward in free fall. Over and over again this happened, like a stone skipping on water, a nauseating cosmic roller coaster, vastly uncomfortable.
Don did not mind. He was a spaceman again; his stomach was indifferent to surges of acceleration or even the absence thereof. At first he was excited at being back in the clouds of Venus; presently he was bored. At long, long last he was awakened by a change in motion; the craft was whistling down in its final glide, the pilot stabbing ahead with radar for his landing. Then the Cyrus Buchanan touched, bounced, and quivered to the rushing water under her hull. She slowed and stopped. After a considerable wait she was towed to her berth. The steward stood up and shouted, “New London! Republic of Venus! Have your papers ready.”
