Surely (I am not a physicist) one kind of an invisible plane Would be one where all the light that hits it is absorbed - comes into it but does not Reflect off - so the light would be incredibly bright inside. Or would that be just a hole in the sky? I mean that would be a radar invisible plane. Would the scattering of the light around the rest of the sky be enough to occlude your “hole” ?
