He looked around, noting that the air over the Administrative Group was comparatively free of traffic. To be sure, he would have to cross the traffic lines, but he could take the upper lanes, avoiding all but official traffic. A guard might challenge, but he could use his identifying lights. He wouldn't be halted. He corrected his course a little, glanced at the altimeter, and put his ship into a climb. At length, he eased his ship over the parklike area over Administrative Square and hovered over the parking entry. A light blinked on his dash, to tell him that all the official spaces were occupied. He grunted. "Wonder they couldn't leave a clear space in Official. They know I'm coming in for conference." He moved the control wheel, allowing his ship to slide over to a shopping center parking slot, and hovered over the entry, debating. He could park here and take the sub-surface to Administrative, or he could use the surface lot just outside of the headquarters group. Of course, the director frowned on use of the surface lot, except in emergency. The underground lots were designated for all normal parking. Morely thought over the problem, ignoring the helis which hovered, waiting for him to clear the center of the landing area. Finally, his hand started for the throttle. He would settle in the landing slot, let the guards shove his heli to a space, and avoid any conflict with the director's orders regarding the surface lot. * * * * * Suddenly, there was a sputtering roar. Someone had become impatient at the delay. A small sports heli swept by, impellers reversed, and dropped rapidly toward the entry to the underground parking space. Morely's ship rocked a little in the air blast. For an instant, Morely felt a sharp pain which gnawed at the pit of his stomach. His head was abruptly light, and his hand, apparently of its own volition, closed over the throttle knob. This joy boy was overdue for a lesson. Morely measured the distance quickly, judging the instant when the other pilot would have to repitch his impellers and halt his downward rush. He allowed his own heavy ship to wallow earthward. Scant feet from ground surface, the sportster pilot flicked his pitch control and pulled his throttle out for the brief burst of power which would allow him to drop gently to the landing platform. Morely grinned savagely as he saw the impellers below him change pitch and start to move faster. He twisted his own impellers to full pitch and pulled out the throttle for a sudden, roaring surge of power, then swung the control column, jerking his ship up and away. As he steadied his heli and cut power, he looked down.
