The moment I wagged back he broke circle and dove. I'd've circled lower. If the whale was down in the Gap itself that might mean a three thousand meter fall. Pulling out would overstrain one's wings. Sailplanes, even the jackboot jobs we flew, are fragile machines never intended for stunt flying.

But I was wingman, responsible for protecting the attack pilot's rear. I winged over and followed, maintaining a constant five hundred meters between us. Light and shadow from clouds and mountains played over his ship, alternately lighting and darkening the personal devices he'd painted on. A death's-head grinned and winked...

I spied the whale. It was working directly toward Beadle. Size and coloring of the gasbag (oblate spheroid sixty meters long, patched in shades from pink to scarlet and sported with odd other colors at organ sites) indicated a juvenile of the Harkness species, that with the greatest potential for destruction. Triangular vanes protruding ten meters from muscle rings on the bag twitched and quivered as the monster strove to maintain a steady course. Atop it in a thin Mohawk swath swayed a copse of treelike organs believed to serve both plant-like and animal digestive and metabolic functions. Some may have been sensory. Beneath it sensory tentacles trailed, stirring fretfully like dreaming snakes on the head of Medusa. If any found food (and anything organic was provender for a Harkness), it'd anchor itself immediately. Hundreds more tentacles would descend and begin lifting edibles to mouths in a tiny head-body tight against the underside of the gasbag. There'd be a drizzling organic rainfall as the monster dumped ballast/waste. Migrating whale herds could devastate great swaths of countryside. Fortunately for Ubichi's operations, the mating seasons were infrequent.
