Chase reached for the button, but Blanchard's cybernetic command was far faster. The drone's rack cover slammed open, and Chase heard the drone roar from its mounting. On the monitor showing the drone's point of view Chase saw only sky, so he eased the small joystick forward. Regardless of its actual orientation, he'd be pushing the drone toward the ground. The horizon and then the ground slid into view, and Chase caught the edge of the Azzie chopper as it slipped from sight. The solid-fuel booster on the drone kept it flying at a constant speed, and Chase began to swing it around toward the Aztlan helicopter.
