Part 12 (1/2)

He heard a whirring sound, and saw the magnetic mooring cables jerk. The s.h.i.+p was preparing for blastoff. Automatic motors were drawing the cables and grappling plates into the hull. Moving quickly, Tom reached the rear cable. Here was his anchor, something to hold him tight to the hull! With one hand he loosened the web belt of his suit, looped it over a corner of the grappling plate as it pulled in to the hull.

The plate pulled tight against the belt. Each plate fit into a shallow excavation in the hull, fitting so tightly that the plates were all but invisible when they were in place. Tom felt himself pulled in tightly as the plate gripped the belt against the metal, and the whirring of the motor stopped.

For an instant it looked like the answer. The belt was wedged tight ... he couldn't possibly pull loose without ripping the nylon webbing of the belt. But a moment later the motor started whirring again.

The plate pushed out from the hull a few inches, then started back, again pulling in the belt....

A good idea that just wouldn't work. The automatic machinery on a s.p.a.ces.h.i.+p was built to perfection; nothing could be permitted to half-work. Tom realized what was happening. Unless the plate fit perfectly in its place, the cable motor could not shut off, and presently an alarm signal would start flas.h.i.+ng on the control panel.

He pulled the belt loose, reluctantly. He would have to count on his boots and his hand-pads alone.

He searched the rear hull, looking for some break in the polished metal that might serve as a toehold. To the rear the fins flared out, supported by heavy struts. He made his way back, crouching close to the hull, and straddled one of the struts. He jammed his magnetic boots down against the hull, and wrapped his arms around the strut with all his strength.

Clinging there, he waited.

It wasn't a good position. The metal of the strut was polished and slick, but it was better than trying to cling to the open hull. He tensed now, not daring to relax for fear that the blastoff accelleration would slam him when he was unprepared.

Deep in the s.h.i.+p, the engines began to rumble. He felt it rather than heard it, a low-pitched vibration that grew stronger and stronger.

The Ranger would not need a great thrust to move away from the orbit-s.h.i.+p ... but if they were in a hurry, they might start out at nearly Mars-escape....

The jets flared, and something slammed him down against the fin strut.

The Ranger moved out, its engines roaring, accellerating hard. Tom felt as though he had been hit by a ton of rock. The strut seemed to press in against his chest; he could not breathe. His hands were sliding, and he felt the pull on his boots. He tightened his grip desperately. This was it. He had to hang on, _had_ to hang on....

He saw his boot on the hull surface, sliding slowly, creeping back and stretching his leg, suddenly it broke loose; he lurched to one side, and the other boot began sliding. There was a terrible ache in his arms, as though some malignant giant were tearing at him, trying to wrench him loose as he fought for his hold.

There was one black instant when he knew he could not hold on another second. He could see the blue flame of the jet streaming behind him, the cold blackness of s.p.a.ce beyond that. It had been a fool's idea, he thought in despair, a million-to-one shot that he had taken, and lost....

And then the pressure stopped. His boots clanged down on the hull, and he almost lost his hand-grip. He stretched an arm, shook himself, took a great painful breath, and then clung to the strut, almost sobbing, hardly daring to move.

The ordeal was over. Somewhere, far ahead, an orbit-s.h.i.+p was waiting for the Ranger to return. He would have to be ready for the braking thrust and the side-maneuvering thrusts, but he would manage to hold on.

Crouching against the fin, he would be invisible to viewers on the orbit-s.h.i.+p ... and who would be looking for a man clinging to the outside of a scout-s.h.i.+p?

Tom sighed, and waited. Jupiter Equilateral would have its prisoners, all right. He wished now that he had not discarded the stunner, but those extra pounds might have made the difference between life and death during the blastoff. And at least he was not completely unarmed. He still had Dad's revolver at his side.

He smiled to himself. The pirates would have their prisoners, indeed ... but they would have one factor to deal with that they had not counted on.

For Greg it was a bitter, lonely trip.

After ten hours they saw the huge Jupiter Equilateral orbit-s.h.i.+p looming up in the viewscreen like a minor planet. Skilfully Doc maneuvered the s.h.i.+p into the launching rack. The guards unstrapped the prisoners, and handed them pressure suits.

Moments later they were in a section in crews' quarters where they stripped off their suits. This...o...b..t-s.h.i.+p was much larger than Roger Hunter's; the gravity was almost Mars-normal, and it was comforting just to stretch and relax their cramped muscles.

As long as they didn't think of what was ahead.

Finally Johnny grinned and slapped Greg's shoulder. ”Cheer up,” he said.
