Opposition to the bare idea of a Space Platform, for instance, from the moment it was first proposed. Every dictator protested bitterly. Even politicians out of office found it a subject for rabble-rousing harangues. The nationalistic political parties, the peddlers of hate, the entrepreneurs of discord—every crank in the world had something to say against the Platform from the first. When they did not roundly denounce it as impious, they raved that it was a scheme by which the United States would put itself in position to rule all the Earth. As a matter of fact, the United States had first proposed it as a United Nations enterprise, so that denunciations that politicians found good politics actually made very poor sense. But it did not get past the General Assembly. The proposal was so rabidly attacked on every side that it was not even passed up to the Council—where it would certainly have been vetoed anyhow.
But it was exactly that furious denunciation which put the Platform through the United States Congress, which had to find the money for its construction.
In Joe’s eyes and in the eyes of most of those who hoped for it from the beginning, the Platform’s great appeal was that it was the necessary first step toward interplanetary travel, with star ships yet to come. But most scientists wanted it, desperately, for their own ends. There were low-temperature experiments, electronic experiments, weather observations, star-temperature measurements, astronomical observations.... Any man in any field of science could name reasons for it to be built. Even the atom scientists had one, and nearly the best. Their argument was that there were new developments of nuclear theory that needed to be tried out, but should not be tried out on Earth. There were some reactions that ought to yield unlimited power for all the world from really abundant materials. But there was one chance in fifty that they wouldn’t be safe, just because the materials were so abundant. No sane man would risk a two-per-cent chance of destroying Earth and all its people, yet those reactions should be tried. In a space ship some millions of miles out in emptiness they could be. Either they’d be safe or they would not. But the only way to get a space ship a safe enough distance from Earth was to make a Space Platform as a starting point. Then a ship could shoot away from Earth with effectively zero gravity and full fuel tanks. The Platform should be built so civilization could surge ahead to new heights!
But despite these excellent reasons, it was the Platform’s enemies who really got it built. The American Congress would never have appropriated funds for a Platform for pure scientific research, no matter what peacetime benefits it promised. It was the vehemence of those who hated it that sold it to Congress as a measure for national defense. And in a sense it was.
These were ironic aspects Joe hadn’t thought about before, just as he hadn’t thought about the need to defend the Platform while it was being built. Defending it was Sally’s father’s job, and he wouldn’t have a popular time. Joe wondered idly how Sally liked living out where the most important job on Earth was being done. She was a nice kid. He remembered appreciatively that she’d grown up to be a very good-looking girl. He tended to remember her mostly as the tomboy who could beat him swimming, but the last time he’d seen her, come to think of it, he’d been startled to observe how pretty she’d grown. He didn’t know anybody who ought to be better-looking.... She was a really swell girl....
He came to himself again. There was a change in the look of the sky ahead. There was no actual horizon, of course. There was a white haze that blended imperceptibly into the cloud layer so that it was impossible to tell where the sky ended and the clouds or earth began. But presently there were holes in the clouds. The ship droned on, and suddenly it floated over the edge of such a hole, and looking down was very much like looking over the edge of a cliff at solid earth illimitably far below.
The holes increased in number. Then there were no holes at all, but only clouds breaking up the clear view of the ground beneath. And presently again even the clouds were left behind and the air was clear—but still there was no horizon—and there was brownish earth with small green patches and beyond was sere brown range. At seventeen thousand feet there were simply no details.
Soon the clouds were merely a white-tipped elevation of the white haze to the sides and behind. And then there came a new sound above the droning roar of the motors. Joe heard it—and then he saw.
Something had flashed down from nowhere. It flashed on ahead and banked steeply. It was a fighter jet, and for an instant Joe saw the distant range seem to ripple and dance in its exhaust blast. It circled watchfully.
The transport pilot manipulated something. There was a change in the sound of the motors. Joe followed the co-pilot’s eyes. The jet fighter was coming up astern, dive brakes extended to reduce its speed. It overhauled the transport very slowly. And then the transport’s pilot touched one of the separate prop-controls gently, and again, and again. Joe, looking at the jet, saw it through the whirling blades. There was an extraordinary stroboscopic effect. One of the two starboard propellers, seen through the other, abruptly took on a look which was not that of mistiness at all, but of writhing, gyrating solidity. The peculiar appearance vanished, and came again, and vanished and appeared yet again before it disappeared completely.
