The Black Star Passes by John W. Campbell (read e book .txt) 📕

in a straight climb, the rocket ship standing on its tail, the rocket blast roaring out behind a stream of fire a half mile long.

The pirate was climbing at a speed that would have distanced any other machine the world had ever seen, but the tenacious opponent behind him clung ever tighter to the tiny darting thing. He had released great clouds of his animation suspending gas. To his utter surprise, the ship behind him had driven right through it, entirely unaffected! He, who knew most about the gas, had been unable to devise a material to stop it, a mask or a tank to store it, yet in some way these men had succeeded! And that hurtling, bullet-shaped machine behind! Like some miniature airship it was, but with a speed and an acceleration that put even his ship to shame! It could twist, turn, dive, rise and shoot off on the straightaway with more flashing speed than anything aloft. Time and again he tried complicated maneuvers that strained him to the utmost, yet that machine always followed after him!

There was one more thing to do. In outer space his rockets would support him. In a straight climb he shot up to the blazing sun above, out into space, while the sky around him grew black, and the stars shone in solemn splendor around him. But he had eyes for only one thing, the shining car that was rising with more than equal speed behind him. He knew he must be climbing over two thousand miles an hour, yet the tracker came ever closer. Just out of sighting range for the machine gun now⁠ ⁠… in a moment⁠ ⁠… but, she was faltering!

The men in the machine behind sat white-lipped, tense, as the whirling shocks of sudden turns at terrific speed twisted the gyroscopic seats around like peas in a rolling ball. Up, down, left, right, the darting machine ahead was twisting with unbelievable speed. Then suddenly the nose was pointed for the zenith again, and with a great column of flame shooting out behind him, he was heading straight toward space!

“If he gets there, I lose him, Morey!” said Arcot. The terrific acceleration of the climb seemed to press them to their seats with a deadly weight. It was labor to talk⁠—but still the car ahead shot on⁠—slowly they seemed to be overhauling him. Now that the velocities were perforce lowered by the effects of gravity, and the air resistance of the atmosphere was well nigh gone, only the acceleration that the human body could stand was considered. The man ahead was pushing his plane ahead with an acceleration that would have killed many men!

Slowly the acceleration of the machine was falling. Arcot pushed the control over to the last ampere, and felt the slight surge, as greater power rushed through the coils momentarily. Soon this was gone too, as the generator behind faltered. The driving power of the atmospheric heat was gone. More than sixty miles below them they could see the Earth as a greenish brown surface, slightly convex, and far to the east they could distinguish a silvery line of water! But they had no eyes but for the column of shooting flame that represented the fleeing raider! Out in airless space now, he was safe from them. They could not follow. Arcot turned the plane once more, parallel to the Earth, watching the plane above through the roof window. Slowly the machine sank to the fifty-mile level, where there was just sufficient air to maintain it in efficient operation.

“Well, he beat us! But there is only one thing for us, to do. He must hang there on his rockets till we leave, and we can hang here indefinitely, if we can only keep this cabin decently warm. He has no air to cool him, and he has the sun to warm him. The only thing that is worrying him right now is the heat of his rockets. But he can throw most of that out with the gases. Lord, that’s some machine! But eventually his rockets will give out, and down he will come, so we’ll just hang here beneath him and⁠—whoa⁠—not so fast⁠—he isn’t going to stay there, it seems; he is angling his ship off a bit, and shooting along, so that, besides, holding himself up, he is making a little forward progress. We’ll have to follow! He’s going to do some speeding, it seems! Well, we can keep up with him, at our level.”

“Dick, no plane ever made before would have stood the terrific pulls and yanks that his plane got. He was steering and twisting on the standard type air rudders, and what strains he had! The unique type of plane must be extremely strong. I never saw one shaped like his before, though⁠—it is the obvious shape at that! It was just a huge triangular arrowhead! Did you ever see one like it?”

“Something like it, yes, and so have you. Don’t you recognize that as the development of the old paper gliders you used to throw around as a kid? It has the same shape, the triangular wings with the point in the lead, except that he undoubtedly had a slight curve to the wings to increase the efficiency. Something like the flying wings of fifty years ago. I hope that man is only a kleptomaniac, because he can be cured of that, and I may then have a new laboratory partner. He has some exceedingly intelligent ideas!

“He’s an ingenious man, but I wish he didn’t store quite so much fuel in his rocket tubes! It’s unbearably cold in here, and I can’t sacrifice any power just for comfort. The rocket ship up there seems to be getting more and more acceleration in the level. He has me dropping steadily to get air to run the generator. He is going fast enough!”

They followed beneath the pirate, faster and faster as the rockets of the ship began to push it forward more and
