Barlennan tore his attention from the screen with some reluctance. “I’d rather watch the picture, but it would probably be better for me to get used to the sight of flying things,” he said. “From which side will it come?”
“The east, I should expect. I have given Mack a careful description of the layout here, and he already had photographs; and I know an approach from that direction will be somewhat easier, as he is now set. I’m afraid the sun is interfering at the moment with your line of vision, but he’s still about forty miles up — look well above the sun.”
Barlennan followed these instructions and waited. For perhaps a minute he saw nothing; his eye was caught by a glint of metal some twenty degrees above the rising sun.
“Altitude ten — horizontal distance about the same,” Lackland reported at the same moment. “I have him on the scope here.”
The glint grew brighter, holding its direction almost perfectly — the rocket was on a nearly exact course toward the dome. In another minute it was close enough for details to be visible — or would have been, except that everything was now hidden in the glare of the rising sun. Mack hung poised for a moment a mile above the station and as far as to the east; and as Belne moved out of line Barlennan could see the windows and exhaust ports in the cylindrical hull. The storm wind had dropped almost completely, but now a warm breeze laden with a taint of melting ammonia began to blow from the point where the exhaust struck the ground. The drops of semiliquid spattered on Barlennan’s eye shells, but he continued to stare at the slowly settling mass of metal. Every muscle in his long body was at maximum tension, his arms held close to his sides, pincers clamped tightly enough to have shorn through steel wire, the hearts in each of his body segments pumping furiously. He would have been holding his breath had he possessed breathing apparatus at all similar to that of a human being. Intellectually he knew that the thing would not fall — he kept telling himself that it could not; but having grown to maturity in an environment where a fall of six inches was usually fatally destructive even to the incredibly tough Mesklinite organism, his emotions were not easy to control. Subconsciously he kept expecting the metal shell to vanish from sight, to reappear on the ground below flattened out of recognizable shape. After all, it was still hundreds of feet up…
On the ground below the rocket, now swept clear of snow, the black vegetation abruptly burst into flame. Black ash blew from the landing point, and the ground itself glowed briefly. For just an instant this lasted before the glittering cylinder settled lightly into the center of the bare patch.
Seconds later the thunder which had mounted to a roar louder than Mesklin’s hurricanes died abruptly. Almost painfully, Barlennan relaxed, opening and shutting his pincers to relieve the cramps.
“If you’ll stand by a moment, I’ll be out with the radios,” Lackland said. The commander had not noticed his departure, but the Flyer was no longer in the room. “Mack will drive the crawler over here — you can watch it come while I’m getting into armor.”
Actually Barlennan was able to watch only a portion of the drive. He saw the rocket’s cargo lock swing open and the vehicle emerge; he got a sufficiently good look at the crawler to understand everything about it — he thought — except what made its caterpillar treads move, It was big, easily big enough to hold several of the Flyer’s race unless too much of its interior was full of machinery. Like the dome, it had numerous and large windows; through one of these in the front the commander could see the armored figure of another Flyer, who was apparently controlling it. Whatever drove the machine did not make enough noise to be audible across the mile of space that still separated it from the dome.
It covered very little of that distance before the sun set, and details ceased to be visible. Esstes, the smaller sun, was still in the sky and brighter than the full moon of Earth, but Barlennan’s eyes had their limitations. An intense beam of light projected from the crawler itself along its path, and consequently straight toward the dome, did not help either. Barlennan simply waited. After all, it was still too far for really good examination even by daylight, and would undoubtedly be at the Hill by sunrise.
