Since he had no real intention of doing so, he wondered why he had even brought the sergeant. Purely as a ceremonial bodyguard, he supposed—the Marines performed shipboard duties for the Space Force similar to those they always had for the Navy, although their EVA role was a new wrinkle for them. Anyway, having him along made DiFalco feel better.
Gunnery Sergeant Joel Thompson, USMC, was not a particularly huge man. In fact, he was only slightly bigger than the six feet and one hundred eighty pounds maintained by DiFalco, who worked at keeping in shape—largely, as he admitted to himself, because he was reaching the age at which a flat stomach was an emblem of self-discipline. But vanity had nothing to do with the sergeant's unrelieved musculature, without an ounce of efficiency-impairing fat. He was not an easy man to know, but he was as formidable and dependable as he looked. And his stubbornness was a force of nature.
A faint boom sounded through the shuttle as it made airlock-to-airlock contact with the UFO's hull and instruments confirmed magnetic seal attachment. For a moment, the two of them sat in silence as if awaiting something, then exchanged quick, sheepish smiles and proceeded to don their vac suit helmets. DiFalco's mounted a videocam whose continuous transmission to Andy J. would, he guessed, be of some interest to Levinson and everyone else who could contrive an excuse for being near a screen. Like their helmet communicators, it would be relayed by the shuttle's more powerful comm equipment; they shouldn't be out of contact with the big ship, barring intentional jamming by the . . . aliens, he supposed he had to call them. Concentrating grimly on the the concrete and the routine, he led the way to the airlock.
Decompression completed, their outer door slid open to reveal, as he had more than half expected, the UFO's airlock similarly open to vacuum. They floated from one chamber into the other, and the strange door sealed behind them. There. That was it. Shouldn't I have said something historical before stepping across?
"Can you hear me, XO? Are you getting this?"
"Barely." Levinson's voice came faintly. "The transmission sucks. Swing a little to your left, will you . . . there! I wanted to get those instructions, or whatever they are, on the wall . . . shit!" The light that awakened just above the odd, cursive lettering startled DiFalco almost as much as it did Levinson, whose picture it momentarily overloaded like a flash bulb.
Immediately, DiFalco began to feel the return of outside air pressure.
Sergeant Thompson studied a readout on the bulky equipment he was carrying. "Skipper"—it was one of the things DiFalco had stopped trying to break him of—"pressure is almost up to one bar. And the initial reading shows nitrogen and oxygen in the right percentages."
"Did you copy that, XO?" Levinson confirmed, and Difalco continued. "All right. I am going to open my faceplate." Ignoring Thompson's disapproving frown, he did so, holding his breath. The air was a little warmer than Andy J. 's. He was preparing to take an experimental breath when the light went out and the inner door slid open. Lightheaded as he was, nothing else seemed to register. He expelled his breath and pushed himself across the threshold into the passageway beyond . . . .
The universe fell on him, slamming him to the deck.
Lying there, he heard Levinson's shouts and Thompson's bellows as if from a great distance, for reality had, for him, suddenly narrowed to two impossible facts. One was that he had just floated directly from free fall into a gravity field that had absolutely no business being there. (How strong was it? Two gees, surely. No, make it three.)
The other was the pair of feet, in utilitarian-looking boots of some unfamiliar material, planted on the deck a few inches from his face. His eyes travelled up the legs and body, the videocam travelling with them . . . and Levinson's frantic voice trailed
