When he awoke he was in a minute cabin, lying on a small cot. The cabin was a-buzz with the sound of motors, and it swayed gently. Vinson knew he was flying--flying in a large aircraft, kidnapped and helpless. He beat on the door with his fists, then shattered a metal fitting against it; both attempts were equally futile. He tried the cabin call-button with deliberate intent to arouse anger but received no reply. He gave up; they might have disconnected the bell or they may have been ignoring the sound--it was one and the same to Vinson. An hour later a slide in the wall opened and a tray of food came into the room. "So," he said aloud, "they will not even let me see them. How can they hope to keep this secret, and do they think I cannot guess who they are?" Shrugging, Vinson sat down and ate laconically. There was little he could do but wait; eventually someone would come. But Vinson could not accept his fate quietly for very long. The narrow confines of the cabin left him nothing to do but think. He scoured the minute place for something to use as a tool, found the cabin to be clean as the inside of an empty gasoline tin so far as tools went. Not a thing, nothing of any use but the light in the ceiling. But that was a starting point for a trained engineer; Vinson removed the electric light, inserted a coin in the socket, then screwed the lamp back tight then snapped the switch. From somewhere there was a minute _sput_ and all the rest of the lights in the cabin went out. What happened to the rest of the ship was outside of Vinson's knowledge. He only hoped that all the lights were on the same circuit; before anyone could replace the fuse, they would have to clear the short circuit. He waited. And then there was a snicking sound and the door opened automatically. "Now, damn you--" he started. He stepped forward swinging the pillow from the bed, its end torn open, and effectively hurling a snowstorm of feathers at his captive-- Machine! It came forward through the storm of feathers and Vinson leaped back to the bed and tore the mattress from its place. He hurled it on the floor in front of the half-tracks upon which the machine rode. The machine tilted, put out a girder to correct its off-balance position, then came to the floor with a crash as Vinson leaped forward, feet first, to kick the forward corner of the machine around and away from its steadying arm. He leaped over the fallen machine, avoiding a questing girder-and-clutcher by less than inches. He slammed the door behind him, raced down the corridor towards the pilot's compartment. He paused to smash the glass and take a metal crowbar from the fire-case on the wall; then he hit the door with a crash, went into the pilot's cabin with his bar upraised to bring it down on the pilot's head. Vinson stopped on his heels. There was no pilot; just an ultra-complex machine that was fastened to the floor before the controls.
