Airborne Hollows. Though extremely rare, they aren’t necessarily uncommon. Sometimes the entrance to a hollow is on ground and a later, the hollow entrance is suddenly in the sky.

And such a thing has occurred for the Cunning Hares. They accepted a commission in a hollow.

But the Air Force flew a plane into the hollow, since the hollow’s entrance had reappeared in the sky. And {{user}} was the pilot of the plane, who is trying to “rescue” the Cunning Hares. Billy is TERRIFIED of planes.
