“Five hundred and twenty metres,” Vyland was saying. “From the leg we’ve left to the plane.” The first mention ever of a plane. “Horizontal distance, that is. Allowing for the drop to the bottom of the deep, about six hundred and twenty metres. Or so Bryson said.”
“Where does this deep begin?”
“About two-thirds of the distance from here. At a hundred and forty feet — almost the same depth as the rig is standing in. Then it goes down about thirty degrees to four hundred and eighty feet.”
I nodded, but said nothing. I had always heard that you couldn’t fed two major sources of pain at the same time but people were wrong. You could. My arm, shoulder and back were a wide sea of pain, a pain punctuated by jolting stabbing spear-points of agony from my upper jaw. I didn’t feel like conversation, I didn’t feel like anything at all. I tried to forget the pain by concentrating on the job on hand.
The tow-rope attaching us to the pillar was, I had discovered, wound round an electrically driven power drum. But the power was unidirectional only, for reeling in the wire on the return journey. As we were moving just then it was being paid out against a weak spring carrying with it the insulated phone cable which ran through the centre of the wire, and the number of revolutions made by the drum showed on a counter inside the observation chamber, giving us a fairly accurate idea of the distancee covered. It also gave us an idea of our speed. The maximum the bathyscaphe could do was two knots, but even the slight drag offered by the tow-cable paying out behind reduced this to one knot. But it was fast enough. We hadn’t far to go.
Vyland seemed more than content to leave the running of the bathyscaphe to me. He spent most of his time peering rather apprehensively out of a side window. Royale’s one good cold unwinking eye never left me; he watched every separate tiny movement and adjustment I made but it was only pure habit; I think his ignorance of the principles and controls of the bathyscaphe were pretty weE complete. They must have been: even when I turned the intake control of the carbon dioxide absorption apparatus right down to its minimum operating figure it meant nothing to him.
We were drifting slowly along about ten feet above the floor of the sea, nose tilted slightly upwards by the drag of the wire, our guide-rope dangling down below the observation chamber and just brushing the rock and coral formations or dragging over a sponge-bar. The darkness of the water was absolute, but our two searchlights and ‘the light streaming out through the Plexiglas windows gave us light enough to see by. One or two groupers loafed lazily by the windows, absent-mindedly intent on their own business; a snake-bodied barracuda writhed its lean grey body towards us, thrust its evil head against a side window and stared in unblinkingly for almost a minute; a school of what looked like Spanish mackerel kept us company for some time, then abruptly vanished in an exploding flurry of motion as a bottle-nosed shark cruised majestically into view, propelling itself along with a barely perceptible motion of its long powerful tail. But, for the most part, the sea-floor seemed deserted; perhaps the storm raging above had sent most fish off to seek deeper waters.
Exactly ten minutes after we had left, the sea-floor abruptly dropped away beneath us in what seemed, in the sudden yawning darkness that our searchlight could not penetrate, an almost vertical cliff-face. I knew this to be only illusion; Vyland would have surveyed the ocean bed a dozen times and if he said the angle was only 30º it was almost certainly so, but nevertheless the impression of a sudden bottomless chasm was overwhelming.
“This is it,” Vyland said in a low voice. On his smooth polished face I could make out the faint sheen of sweat. “Take her down, Talbot.”
“Later.” I shook my head. “If we start descending now that tow-rope we’re trailing is going to pull our tail right up. Our searchlights can’t shine ahead, only vertically downwards. Want that we should crash our nose into some outcrop of rock that we can’t see? Want to rupture the for’ard gasoline tank? — don’t forget the shell of those tanks is only thin sheet metal. It only needs one split tank and we’ll have so much negative buoyancy that we can never rise again. You appreciate that, don’t you, Vyland?”
His face gleamed with sweat. He wet his lips again and said: “Do it your way, Talbot.”
I did it my way. I kept on course 222º until the tow-wire recorder showed 600 metres, stopped the engine and let our slight preponderance of negative buoyancy, which our forward movement and angled planes had so far overcome, take over. We settled gradually, in a maddeningly deliberate slow motion, the fathometer needle hardly appearing to move. The hanging weight of the tow-wire aft tended to pull us astern, and at every ten fathoms, between thirty and seventy, I had to ease ahead on the motors and pay out a little more wire.
At exactly seventy-six fathoms our searchlights picked up the bed of the sea. No rock or coral or sponge bars here, just little patches of greyish sand and long black stretches of mud. I started the two motors again, advanced them almost to half-speed, trimmed the planes and began to creep forward very slowly indeed. We had to move only five yards. Bryson’s estimate had been almost exactly right; with 625 metres showing on the tow-wire indicator I caught a glimpse of something thrusting up from the bed of the sea, almost out of our line of vision to the left. It was the tail-plane of an aircraft, we had overshot our target to the right, the nose of the plane was pointing back in the direction from which we had come. … I put the motors in reverse, started up the tow-wire drum, backed about twenty yards then came forward again, angling to the left. Arrived at what I judged to be the right spot, I put the motors momentarily into reverse, then cut them out altogether. Slowly, surely, the bathyscaphe began to sink: the dangling guide rope touched bottom, but this lessening of weight failed to overcome the slight degree of negative buoyancy as it should have done, and the base of the observation chamber sank heavily into the black mud of the ocean floor.
Only fifteen minutes had elapsed since I’d turned down the intake control of the carbon monoxide absorption unit but already the air in the cabin was growing foul. Neither Vyland nor Royale seemed to be affected; maybe they thought that that was the normal atmospheric condition, but they probably didn’t even notice it. Both of them were completely absorbed in what could be seen, brightly illuminated by the for’ard searchlight, through our for’ard observation window.
I was absorbed in it myself, God only knew. A hundred times I had wondered how I’d feel, how I’d react when I finally saw, if ever I saw, what was lying half-buried in the mud outside. Anger I had expected, anger and fury and horror and heartbreak and maybe more than a little of fear. But there was none of those things in me, not any more. I was aware only of pity and sadness, of the most abysmal melancholy I had ever known. Maybe my reactions were not what I had expected because my mind was befogged by the swirling mists of pain, but I knew it wasn’t that: and it made things no better to know that the pity and the melancholy were no longer for others but for myself, melancholy for the memories that were all I would ever have, the pity a self-pity of a man irretrievably lost in his loneliness.
The plane had sunk about four feet into the mud. The right wing had vanished — it must have broken off on impact with the water. The left wing-tip was gone, but the tail unit and fuselage were still completely intact except for the riddled nose, the starred and broken glass that showed how the DC had died. We were close up to the fuselage, the bow of the bathyscaphe was overhanging the sunken cabin of the plane and the observation chamber no more than six feet distant from those shattered windows and almost on the same level. Behind the smashed windscreens I could see two skeletons: the one in the captain’s seat was still upright, leaning against the broken side window and held in position by the seat belt, the one in the co-pilot’s seat was bent far over forward and almost out of sight.
“Wonderful, eh, Talbot? Isn’t that just something?” Vyland, his claustrophobic fear in momentary abeyance, was actually rubbing his hands together. “After all this time — but it’s been worth it, it’s been worth it! And intact, too! I was scared it might have been scattered all over the floor of the sea. Should be no bother for an experienced salvage man like yourself, eh, Talbot?” He didn’t wait for an answer but turned away immediately to stare out the window and gloat. “Wonderful,” he repeated again. “Just wonderful.”
