But tropical growth is difficult to land in.

A moment later his swinging body crashed through the branches of a tree, and he pitched forward, unable to control the impetus. A sudden shock of pain stabbed through his head and everything spun dizzily before him. He knew he was falling, jerking down as the parachute ripped on the boughs.
