Teak, brass and a canvas panel stencilled like an old supply crate. Drop a token and you are at the controls of the ranger patrol biplane, running north over the plain — savanna, the river bend, the acacia flats, the escarpment, and Kilimanjaro standing at the top of the run. The poachers' aircraft come down at you in formation. Turn every one of them back, because anything that slips past you is over the herds. Pull Peter's loop when the sky gets too thick, and hold all five sectors to have the Postal Society postmark your own Acacia Patrol stamp.

Arrows or WASD to fly, space to fire, shift to pull the loop. On a touch screen, drag to fly — you fire while you hold, and holding still for a moment pulls the loop.
Three loops a life, and nothing can touch you through the arc. Lead planes drop wing-mates, a wide shot, a spare loop or a pinch of fairy dust. Never let one through to the herds.
