Harry Harrison - A Transatlantic Tunnel, Hurrah!

“A Brabbage engine, one of the largest and most complex ever made.”

“Beautiful indeed!” Gus answered in sincere appreciation, forgetting for the moment his great unhappiness.“I have never seen one this size before. I suppose you have a large memory store?”

“More than adequate for our needs as you can see.” He opened a door with a flourish to disclose serried banks of slowly turning silver disks, all of them perforated with large numbers of small holes. Metal fingers riding on rods brushed the surfaces of the disks, bobbing and clicking when they encountered the openings. There was a continual soft metallic chatter going on, along with some hissing and an occasional clatter. From this welter of sound Clarke must have detected an inconsistency because he cocked his head to one side, listening, then threw open the next panel and seized an oil can from the bench behind them. “A fine device, although it does need upkeep.” He dropped oil on the bearings of a cam follower where it rode up and down on the smoothly formed and complex shape of a brass analog cam. “They are making wholly electric Brabbage engines now, calling them computers as if that made a difference, they are much smaller but still filled with bugs. Give me good solid metal anytime, although we do have trouble with backlash in the gear trains.”

“It is all very interesting…”

“Please excuse me, Washington, no excuse really, bit carried away, dreadfully sorry.” He dropped the oil can, flustered, picked it up again, restored it to the bench, closed the panels and pointed to a door across the room. “If you please, now you’ve seen the Brabbage, right through here. This may interest you more.”

It did indeed, for beyond the door was a great hangar, in the center of which stood the tall, spearlike form of a rocket. Fifty feet or more it reached up, six feet thick at the base, finned and sleek and stern, all of a color, blue-black and striking.

“ Black Knight , our best and most powerful rocket. Completely reliable with a most efficient liquid fuel engine that burns kerosene mixed with peroxide. Very delicate controls. Sends back a radio signal as it goes along that is monitored by the Brabbage engine we have just seen, so that course adjustments can be made in flight. Using this we have been most successful in an experimental program that may soon become a standard practice. Rocket mail, the Post Office is interested as you can well imagine, between here and Croydon. They have one of the electric computers there, pick up the signal as Black Knight comes over the Atlantic and guide her in, cut engines and all that, bring her down by parachute…” His voice ground to a halt as Washington turned slowly to stare at him, fix him with a terrible gaze. When he spoke again it was hurriedly, stumbling at times. “No, hear me out please, experimental program, nothing more. Worked every time so far, mail got through, but who knows. Tremendous acceleration. Kill a person dead perhaps. But other experiments, sent a chimp last time, Daisy, sweet thing, in the Regent’s Park Zoo right now, never seemed to phase her, ate a whole hand of bananas when they took her out.”

“If you are saying what I think you are saying, Clarke, why then IS am your man. If you would like «s volunteer to cross the ocean in your piece of fireworks, then I have volunteered. But only if it gets me then by nine ia the morning. Will it?” And indeed that Was what the Devonshire engineer had in mind and the more he explained the more convinced Gus was that victory might still be snatched from the already closing jaws of defeat. The other engineers and the base commander were called in and they conferred, London was contacted on the radio telephone and more conferring was done until, in the end, there were none to say nay and the yea-speakers were overwhelming in numbers and there was no choice but to do this new and wonderful thing.

It was a labor to finish in the few hours that remained, but labor they did. Outside the arctic storm howled and beat in impotent rage against the buildings while inside they worked on the device that would vanquish the storm, vanquish time and space and distance to send a man from the new world to the old in a matter of some few minutes. The rocket was fuelled and readied and all of its complex circuitry tested while, high above, the mechanics labored to install the rubberised lining and to pump in all the gallons of water that would be needed.

“That is the secret,” Clarke explained, eyes glistening with enthusiasm behind the smudged lenses of his glasses. “Amniotic fluid, a secret known to nature and there for the taking had we but the sense to know where to look. But we have at last looked and seen and utilized this secret. As you know 1-G is the force of gravity, gravity as we know it on the surface of the Earth. Acceleration and gravity seem to be identical, or at least that’s what that German chap Einstein who used to be at Oxford says, identical. We accelerate and feel 2-G’s and are uncomfortable, 3-G’s and we suffer, 5-G’s, 6-G’s strange things happen, death and heart failure and blackouts, very nasty. But, suspended in a liquid medium, we have had test subjects, simians for the most part, subjected to 50-G’s and they survived in fine fettle. So that is what we are doing how. A space-going womb, ha-ha, you might call it.”

“Submerged all the way? I hope I won’t have to hold my breath?”

“That would be impossible… Oh, pulling my leg, Captain Washington? Oh dear yes! No, indeed, quite comfortable. The water may be chill but you will be wearing a wet suit with an oxygen mask. Quite comfortable indeed.”

Comfortable was not exactly the correct word, Gus thought as helping hands slipped him into the space-going bath. He dropped below the surface and fastened the snaps to his belt as he had been instructed while he breathed slowly and carefully through the mask. It was all quite interesting though there was a moment of disquiet when the distorted faces and hands above him vanished and the nose cone slid into place with a resounding clang. The water carried all the sounds and he could hear the clanking and grinding of metal al the bolts were secured. Then silence?!

This was the worst part, the waiting in the darkness and solitude. Alone, alone as he had never been before in his life, perched atop this column with its cargo of highly combustible fuel. Waiting. He could visualize the roof opening up above the rollers, the preflight check-off, the switches thrown. He had been told this would take a few minutes but had not realized that his time perception would be thrown off to such a degree. Had minutes passed—or hours? Had there been a failure, an accident? Could he escape from here or would he die in a boiling pot atop a fiery column? His imagination’s steamed along in high gear and had he been able to speak he would have shouted aloud so great was the tension at this moment.

And then a sound, a whine and al scream like the souls in the pit in eternal agony. He felt the hair on his I neck stir before he realized that it was just the high-speed pumps going! into operation, forcing the fuel into! the combustion chamber. The flight was beginning! And at the instant he realized that there was a distant rumble and roar that grew fantastically until it beat at his ears so he had to cover them with his hand while something unseen jumped on his chest and battered him down! Blast off!

For a long and unmeasurable time the pressure continued—then suddenly ceased as the engines shut down. The rocket was coasting. In those eternity-long minutes while the engines were working they had burned their way up through the storm and penetrated the atmosphere above and the stratosphere above that until now they were beyond the last traces of airy envelope of the Earth and arcing through the vacuum of space. The Atlantic was a hundred, two hundred miles below them and ahead was England. And the waiting computer at the airport in Croydon, that sleepy little suburb of London, an electric Brabbage engine that was not as reliable as the mechanical one and he hoped that, at least this once, the enthusiastic Captain Clarke would prove to be wrong about the reliability of that machine.
