"There she is!" said General Webb, proudly, gesturing over the railing of the small balcony upon which they stood. "The Whirligig!" "What?" called Secretary of Defense Whitlow, shaking his head to indicate he hadn't heard a word. Somewhat piqued, but resigned, General Webb leaned his wide mouth nearly up against Whitlow's small pink plugged ear, and roared the same information at the top of his lungs. Whitlow, a little stunned by the volume despite the plugs, nodded wearily, to indicate that he'd heard, then asked, in a high, piping voice, "What's it for?" Webb's eyes bulged in their sockets. "Great heavens, man, can't you _see_?" He gestured down at his creation, his baby, his project, as though it were self-evident what its function was. Whitlow strained his eyes to divine anything that might give a clue as to just what the government had been pouring money into for the past eight months. All he saw was what appeared to be a sort of ferris-wheel, except that it was revolving in a horizontal plane. The structure was completely enclosed in metal, and was whirling too fast for even the central shaft to be anything but a hazy, silver-blue blur. "I see it," he shouted, squeakily. "But I don't understand it!" "Come with me," said General Webb, re-opening the door at their backs. He was just about to step through when, with a quick blush of mortification, he remembered the "Top Secret" earplugs. Hastily, averting his face lest the other man see his embarrassment, he returned his plugs to their box, and did the same with Whitlow's. Whitlow was glad when the door closed behind them. "My office is this way," said Webb, striding off in a stiff military manner. Whitlow, with a forlorn shrug, could do nothing but clutch his brief case and follow. * * * * * "It's this way," General Webb began, once they were seated uncomfortably in his office. From a pocket in his khaki jacket, Webb had produced a big-bowled calabash pipe, and was puffing its noxious gray fumes in all directions while he spoke. "Up until the late fifties, war was a simple thing ..." Oh, not the March of Science Speech! said Whitlow to himself. He knew it by heart. It was the talk of the Capitol, and the nightmare of military strategists. As the general's voice droned on and on, Whitlow barely listened. The general, Top Secret or no Top Secret, was divulging nothing that wasn't common knowledge from the ruins of Philadelphia to the great Hollywood crater ... All at once, weapons had gotten _too_ good. That was the whole problem. Wars, no matter what the abilities of the death-dealing guns, cannon, rifles, rockets or whatever, needed one thing on the battlefield that could not be turned out in a factory: Men. In order to win a war, a country must be vanquished. In order to vanquish a country, soldiers must be landed. And that was precisely wherein the difficulty lay: landing the soldiers.
