 After realizing his situation after the crash, why did Rolf laugh?
Sisko Rolf's stocky body was a blur of motion as he cut the rocket jets, doused the twin searchlights, and switched over to the audio beams that served so well on the surface when blind flying was in order.

The ship struck; split open like a rotten squash, and Rolf felt himself being flung far outward through thick blackness.

A hundred paces away Rolf made the dark shapes of armed warriors as they filed downward from the Barrier into the blackened desolation of the desert half of Lomihi.
