They had some measure of anti-gravity to help lift the ship from a planet. About 22%, Hanlon remembered. They still had to use rockets when near a planet—but these present-day rockets were a far cry from the early crude ones with which Snyder and his men had put first ships on the Moon and planets. These could deliver a thrust far more powerful than those early ones.
For long distances they used a type of "warping" that made the ship "skip" along the lines of force that permeate all space. Hanlon had never quite got it firmly fixed in his mind just how this was done, especially the technique of the engines that made it possible. That was "advanced stuff" that the cadets were not taught in their regular courses—it was Post Graduate work for those who were to become Engineering Masters.
As he went up the escalator into the ship Hanlon was met at the outer lock by a deck steward who led him toward the level where his cabin was located.
This was Hanlon's first time aboard one of these luxury liners—how different the deep-piled rugs, the magnificently frescoed passageway walls, the deeply upholstered furniture, from the utilitarian plainness of the Corps' warships on which he had made his practice cruises.
"As you may know, sir," the steward said as they walked along, "there is neither night nor day in space, but we use Terran time on the ship, and lights are turned on and off to conform to the regular Terran day. Breakfast is served from seven to nine, luncheon from twelve to fourteen, and dinner from eighteen to twenty-one."
"Thanks." A credit note changed from hand to hand—tipping was still in style. The obsequious steward gave him further directions for finding the games and recreational rooms, and other points of interest aboard.
Hanlon unpacked, and stored his luggage in the compact closets and then, having heard the first and second warnings, hastened to the observation desk, to watch the take-off. He had barely reached it and been strapped into the acceleration chair turned to face the long, narrow quartzite port, when the blast-off sirens began screaming their third and final warning.
The intra-ship communicators blared, "All passengers and personnel strap in. Five minutes until blast-off ... four minutes ... three ... two ... one ... thirty seconds ... fifteen ... ten ... five, four, three, two, one, BLAST!"
Dimly heard through the insulated hull was what Hanlon knew to be a tremendous crescendo roar of sound, and he was pushed deep into the resilient spring-cushions of his chair. A constricting band seemed to be clamped on his chest, while at the same time there was a curious feeling that he should weigh less but didn't. That was the peculiar sensation the combination of anti-gravity and the thrust of the rockers always gave.
From experience he knew how to regulate his breathing and to let his muscles and nerves relax as much as possible, so that for him there was but a brief moment of discomfort. Then he was able to watch the scene unfolding before and below him.
