"Oh, yeah? Just watch this." The ship thundered to life beneath them and leaped off in a full-throttled take-off. "We're going to crash! That gap isn't wide enough!" The sides of the gap rushed in on the tips of the stubby wings. Brian braced himself for the crash, but it didn't come. At the last possible second, the ship rolled smoothly over. At the moment it flashed through the opening it was stood vertically on edge. * * * * * Crystal held the ship in its roll and completed the maneuver outside the mountain while Brian struggled to get his internal economy back into some semblance of order. "That's some flying," he said as soon as he could speak. Crystal looked at him in surprise. "That's nothing. We Venusians fly almost as soon as we can walk." "Oh--I see," Brian said weakly and a few moments later he really did see. Two big, fast, green ships, carrying the insignia of the Venus Consolidated police, cruised suddenly out from a mountain air station. An aërial torpedo exploded in front of the rebel ship. Crystal's face set in grim lines as she pulled the ship up in a screaming climb. Brian got up off the floor. "You don't have to get excited like that," he complained. "They weren't trying to hit us." "That's what you think," Crystal muttered. "Those children don't play for peanuts." "But, girl, they're just Venus Consolidated police. They haven't got any authority to shoot anyone." "Authority doesn't make much difference to them," Crystal snapped bitterly. "They've been killing people all over the planet. What do you think this revolution is about?" "You must be mistak--" He slumped to the floor as Crystal threw the ship into a mad, rolling spin. A tremendous crash thundered close astern. "I guess that was a mistake!" Crystal yelled as she fought the controls. Brian almost got to his feet when another wild maneuver hurled him back to the floor. The police ship was right on their tail. The girl gunned her craft into a snap Immelmann and swept back on their pursuers, slicing in close over the ship. Brian's eyes bulged as he saw a long streak of paint and metal ripped off the wing of the police ship. He saw the crew battling their controls in startled terror. The ship slipped frantically away and fell into a spin. "That's them," Crystal said with satisfaction. "How are the others doing?" "Look! They're hit!" Brian felt sick. The slower rebel freight ship staggered drunkenly as a torpedo caught it and ripped away half a wing. It plunged down in flames with the white flowers of half a dozen parachutes blossoming around it. Brian watched in horror as the police ship came deliberately about. They heard its forward guns go into action. The bodies of the parachutists jerked and jumped like crazy marionettes as the bullets smashed into them. It was over in a few moments. The dead rebels drifted down into the mist-shrouded depths of the valley.
