The Black Star Passes John W. Campbell (good novels to read in english TXT) 📖

shape up nicely on paper, too, didn’t she. Oh, Fuller, congratulations on your masterpiece. It’s even better looking than we thought, now the copper has added color to it. Doesn’t she look fast? I wish we didn’t need physicists so badly on this trip, so you could go on the first ride with us.”

“Oh, that’s all right, Dick, I know the number of instruments in there, and I realize they will mean a lot of work this trip. I wish you all luck. The honor of having designed the first ship like that, the first heavier-than-air ship that ever flew without wings, jets, or props⁠—that is something to remember. And I think it’s one of the most beautiful that ever flew, too.”

“Well, Dick,” said his father quietly, “let’s get under way. It should fly⁠—but we don’t really know that it will!”

The four men entered the ship and strapped themselves in the gyroscopic seats. One by one they reported ready.

“Captain Mason,” Arcot explained to the Air Inspector, “these seats may seem to be a bit more active than one generally expects a seat to be, but in this experimental machine, I have provided all the safety devices I could think of. The ship itself won’t fall, of that I am sure, but the power is so great it might well prove fatal to us if we are not in a position to resist the forces. You know all too well the effect of sharp turns at high speed and the results of the centrifugal force. This machine can develop such tremendous power that I have to make provision for it.

“You notice that my controls and the instruments are mounted on the arm of the chair really; that permits me to maintain complete control of the ship at all times, and still permits my chair to remain perpendicular to the forces. The gyroscopes in the base here cause the entire chair to remain stable if the ship rolls, but the chair can continue to revolve about this bearing here so that we will not be forced out of our seats. I’m confident that you’ll find the machine safe enough for a license. Shall we start?”

“All right, Dr. Arcot,” replied the Air Inspector. “If you and your father are willing to try it, I am.”

“Ready, Engineer?” asked Arcot.

“Ready, Pilot!” replied Morey.

“All right⁠—just keep your eye on the meters, Dad, as I turn on the system. If the instruments back there don’t take care of everything, and you see one flash over the red mark⁠—yank open the main circuit. I’ll call out what to watch as I turn them on.”

“Ready son.”

“Main gyroscopes!” There was a low snap, a clicking of relays in the rear compartment, and then a low hum that quickly ran up the scale. “Main generators!” Again the clicking switch, and the relays thudding into action, again the rising hum. “Seat-gyroscopes.” The low click was succeeded by a quick shrilling sound that rose in moments above the range of hearing as the separate seat-gyroscopes took up their work. “Main power tube bank!” The low hum of the generator changed to a momentary roar as the relays threw on full load. In a moment the automatic controls had brought it up to speed.

“Everything is working perfectly so far. Are we ready to start now, son?”

“Main vertical power units!” The great ship trembled throughout its length as the lift of the power units started. A special instrument had been set up on the floor beside Arcot, that he might be able to judge the lift of his power units; it registered the apparent weight of the ship. It had read two hundred tons. Now all eyes were fixed on it, as the pointer dropped quickly to 150⁠–⁠100⁠–⁠75⁠–⁠50⁠–⁠40⁠–⁠20⁠–⁠10⁠—there was a click and the instrument flopped back to 300⁠—it was registering in pounds now! Then the needle moved to zero, and the mighty structure floated into the air, slowly moving down the field as a breeze carried it along the ground.

The men outside saw it rise swiftly into the sky, straight toward the blue vault of heaven. In two or three minutes it was disappearing. The glistening ship shrank to a tiny point of light; then it was gone! It must have been rising at fully three hundred miles an hour!

To the men in the car there had been a tremendous increase in weight that had forced them into the air cushions like leaden masses. Then the ground fell away with a speed that made them look in amazement. The house, the construction shed, the lake, all seemed contracting beneath them. So quickly were they rising that they had not time to adjust their mental attitude. To them all the world seemed shrinking about them.

Now they were at a tremendous height; over twenty miles they had risen into the atmosphere; the air about them was so thin that the sky seemed black, the stars blazed out in cold, unwinking glory, while the great fires of the sun seemed reaching out into space like mighty arms seeking to draw back to the parent body the masses of the wheeling planets. About it, in far flung streamers of cold fire shone the mighty zodiacal light, an Aurora on a titanic scale. For a moment they hung there, while they made readings of the meters.

Arcot was the first to speak and there was awe in his voice. “I never began to let out the power of this thing! What a ship! When these are made commercially, we’ll have to use about one horsepower generators in them, or people will kill themselves trying to see how fast they can go.”

Methodically the machine was tried out at this height, testing various settings of the instruments. It was definitely proven that the values that Arcot and Morey had assigned from purely theoretical calculations were correct to within one-tenth of one percent. The power absorbed by the machine they knew and had calculated, but the terrific power of the driving units was far beyond
