Military: Digital camouflage- now on warplanes

I've posted before about digital camouflage being used on military uniforms.  Now, StrategyPage tells us about how it is being used on warplanes, at least on the tops of the airplanes. On the bottoms, which would be seen by people looking up at the sky, they are still using a sky-colored monochrome.  Interestingly, there are multiple patterns for the top sides to match different terrains, such as arctic and desert.
