It was a measure of the Aztlan's triumph that only a bare half-dozen police 'copters patrolled the empty skies above the parade route. The aliens had done this--had conquered the world without firing a shot or speaking a word in anger. They had wooed Earth with understanding patience and superlative guile--and Earth had fallen into their hands like a lovesick virgin! There never had been any real opposition, and what there was had been completely ineffective. Most of those who had opposed the aliens were out of circulation, imprisoned in correctional institutions, undergoing rehabilitation. Rehabilitation! a six bit word for dehumanizing. When those poor devils finished their treatment with Aztlan brain-washing techniques, they would be just like these sheep below, with the difference that they would never be able to be anything else. But these other stupid fools crowding the sidewalks, waiting to hail their destruction--these were the ones who must be saved. They--not the martyrs of the underground, were the important part of humanity. A police 'copter windmilled slowly down the avenue toward his hiding place, the rotating vanes and insect body of the craft starkly outlined against the jagged backdrop of the city's skyline. He laughed soundlessly as the susurrating flutter of the rotor blades beat overhead and died whispering in the distance down the long canyon of the street. His position had been chosen with care, and was invisible from air and ground alike. He had selected it months ago, and had taken considerable pains to conceal its true purpose. But after today concealment wouldn't matter. If things went as he hoped, the place might someday become a shrine. The idea amused him. Strange, he mused, how events conspire to change a man's career. Seven years ago he had been a respected and important member of that far different sort of crowd which had welcomed the visitors from space. That was a human crowd--half afraid, wholly curious, jostling, noisy, pushing--a teeming swarm that clustered in a thick disorderly ring around the silver disc that lay in the center of the International Airport overlooking Puget Sound. Then--he could have predicted his career. And none of the predictions would have been true--for none included a man with a rifle waiting in a blind for the game to approach within range.... The Aztlan ship had landed early that July morning, dropping silently through the overcast covering International Airport. It settled gently to rest precisely in the center of the junction of the three main runways of the field, effectively tying up the transcontinental and transoceanic traffic. Fully five hundred feet in diameter, the giant ship squatted massively on the runway junction, cracking and buckling the thick concrete runways under its enormous weight.
