Alien Emergencies - James White [193]
“Why—” Conway began, shaking his head in momentary confusion. He had been about to list his own problems and requirements and found himself suddenly on the receiving end.
“Very well, Doctor, I’ll state the problem first,” the Fleet Commander said, frowning as he nodded to someone out of sight. The screen blanked for a few seconds, then it displayed a black field on which there was a thick, vertical gray line. At the lower end of the line a fat red box appeared and on the opposite end a blue circle. Dermod went on briskly, “We now have a pretty accurate idea of the configuration of the alien ship, and I am showing you a very simple representation because I haven’t time to do otherwise right now.
“The ship had a central stem, the gray line,” Dermod explained, “with the power plant and thrusters represented by the red box aft and the forward-mounted sensors and navigation systems shown as a blue circle. Since the ship’s occupant was unconscious, all of these systems were fully automatic. The stem also provided the anchoring points for the structure which supported the inhabited coil. You will see that the main supports are angled forward to compensate for stresses encountered while the vessel was under power and during the landing maneuver.”
A forest of branches grew suddenly from the stem, making it look like a squat, cylindrical Christmas tree standing in its red tub and with a bright-blue fairy light at the top. Then the continuous spiral of linked hibernation compartments was attached to the ends of the branches, followed by the spacing members which separated each loop of the coil, and the picture lost all resemblance to a tree.
“The coil diameter remains constant throughout at just under five hundred meters,” the Fleet Commander’s voice continued. “Originally there were twelve turns of the coil and, with each hibernation cylinder measuring twenty meters in length, this means there were roughly eighty hibernating CRLTs in every loop of the coil and close on one thousand of the beings on the complete ship.
“Every loop of the coil was separated by a distance of seventy meters, so that the total height of the coilship was just over eight hundred meters. We were puzzled by this separation since it would have been structurally much simpler laying one on top of the other, but we now believe that the open coil configuration was designed both to reduce and localize meteorite collision damage and remove the majority of the hibernation compartments as far as possible from radiation leakage from the reactor at the stern. While encased in its rather unusual vessel we think the creature traveled tail-first so that its thinking end was at the stern to initiate disembarkation following the landing. Unfortunately, the stern section had to be heavier and more rigid than the forward structure since it had to support the weight of the vessel during deceleration and landing, and so it was the stern which sustained most of the damage when the collision occurred, and most of the CRLT casualties were from the sternmost loop of the coil.”
According to Vespasian’s computer’s reconstruction, the vessel had been in direct head-on collision with a large meteor, and the closing velocities involved had been such that the whole central stem had been obliterated, as if an old-time projectile hand weapon had been used to remove the core of an apple. Only a few scraps of debris from the power unit and guidance system remained—enough for identification purposes but not for reconstruction—and the shock of the collision had shaken the overall coil structure apart.
On the screen the widely scattered hibernation compartments came together again into a not quite complete coil: There were several sections missing, particularly near the stern. Then the stem, its power and guidance systems, and the entire support structure disappeared
