Soon they arrived at their objective and maintained a position well in the van, but not sufficiently far ahead of the rest to call forth a restraining ray from their captors. Already strongly affected by the gravitational pull of the mass of the satellite, many of the smaller portions of the wreck, not directly held by the tractors, began to separate from the main mass. As each bit left its place another beam leaped out, until it became apparent that no more were available, and Stevens strapped the girl and himself down before two lookout plates.

Day after day the brilliant sphere flew toward distant Saturn, with the wreckage of the Forlorn Hope in tow.

Several light tractor beams did not have the power of one heavy-duty one, simply because it was difficult to coordinate them. To be at all effective, paired tractors had to lift at the same time and yank in the same direction.

Her pilot completed his final approach, and the cutter shivered as Warlock’s tractors captured it. It rolled on its gyros, aligning itself with the heavy cruiser’s internal gravity as the brilliantly-lit cavern of Warlock’s boat bay engulfed them, then settled into the docking cradle.
