as a "proof-of-concept" of the stealth features it didn't need particularly sophisticated controls.

Might if it were an operational affair.

Using light as "camouflage" is an old, very effective trick in some circumstances. I remember seeing a movie of tanks against the horizon, with lights off and on.

With the lights off they were a perfect target, made your mouth water. With the lights on their sides turned on there was absolutely no indication there was anything there.

On a bright day in open terrain a hide could be "camouflaged" with light while it was being dug, almost anything hidden from some angles.

Sort of like a Great White shark against the surface of the ocean.

I wonder how hard it would be to disrupt a fly-by-wire planes' controls with very strong directed RF?

They must be shielded to a great extent, wonder if that could be overridden. By something besides a chemical explosion, I mean.
