An infrared light for active infrared illumination could appear dark red, but probably wouldn't on a military drone. It would probably filter out all visible frequencies.

Thanks for your account, these things will show up again if they are actively used. There's no question that such an aircraft could be built, I've been thinking about it myself. (Strong aviation interest).

That would be really cool, if you can build something like that! I'm really interested in your findings, would you drop me a line on torchat (see profile) in case you know more about it?
