murmured. And then something strange happened. The foremost plane that had been straining to reach them, faltered in midair, seemed to hang there for a moment, then, dropping one wing, went into a spiral dive that increased in speed until it seemed a boy’s top, spinning in the sky. Dragging her eyes from this fascinating and terrible sight, she looked for the other planes. They, too, were going down, but under control.

He’s gone to join his ancestors.” “You mean—”
