The Harkness swelled ahead. Horst would be fingering his trigger ring, worrying his sights. I stopped watching for mantas and adjusted my dive so Horst wouldn't be in line when I fired...

Flashing lights, hasty, almost panicky. I read, then glanced out right and up, spied the manta pair. From high above the Harridans they arrowed toward the whale, tips and trailing edges of their wings rippling as they adjusted dive to each vagary of canyon air. But they were a kilometer above and would be no worry till we'd completed our pass. And the other two ships of our flight would be after them, to engage while Horst and I completed the primary mission.

The relationship between mantas and whales had never, to that time, been clearly defined. The mantas seemed to feed among the growths on whale backs, to attach themselves in mated pairs to particular adults, which they fiercely defended, and upon which they were apparently dependent. But nothing seemed to come the other way. The whales utterly ignored them, even as food. Whales ignored everything in the air, though, enduring our attacks as if they weren't happening. If not for the mantas, the extermination program would've been a cakewalk.

But mantas fought at every encounter, almost as if they knew what we were doing. A year earlier they'd been little problem. Then we'd been sending single flights after lone wandering whales, but as migratory pressures built the manta population had increased till we were forced to fight three or four battles to each whale attack-of which maybe one in twenty resulted in a confirmed kill. Frustrating business, especially since self-defense distracted so from our primary mission.

Luckily, the mantas had only one inefficient, if spectacular,

weapon, the lightning they hurled.

That fool von Drachau dropped flaps to give himself more firing time. Because I began overtaking him, I had to follow suit. My glider shuddered, groaned, and an ominous snap came from my right wing. But nothing fell apart.
