Subject: [PATCH] Ensure that the aircraft model is in the same clip plane as
everything else and *doesn't* clear the z-buffer when in external view;
tighten the far plane for internal view back to 100m to give us maximum
precision (this will be important for some instruments; I might even move it
to 50m).
