Basic Information
During the ages before the impact there. were ongoing development and testing of electrochromatic panels as part of innovations relevant to "daytime-stealth" capabilities which have within the last 20 years been rediscovered.
The electrochromatic panels are comprised of thousands of tiny sensors that function as video-cameras that take images of background scenaries, transferring them to the other panels on the other side of the aircraft. This gives the illusion that the aircraft is almost transparent. What the ground observer sees is whatever background images behind (or above) the body of the aircraft that are transposed to the "observer's" side of the body of the aircraft.
That an ongoing research, development and testing of such electrochromatic panels at locations in the science counsels headquarters. and the technology may soon be perfected for military use. .
