That was an experiment in Philadelphia -- and it was to make a ship disappear, not just "seem" to disappear. On another note, this could be old technology. I believe I saw this stuff on a plane in the late 70's.

Seems I remember something that happened around WWII, that involved using Magnetic waves to make a Destroyer/Aircraft Carrier disappear. From what I understand the outcome of that experiment is still kind of hush, hush.

A simple technique for greatly reducing visibility of antisub aircraft was developed about 1943. A row of lights was mounted on or near the wing leading edge, set up so that the brightness could be adjusted to match the background brightness of the sky, making the aircraft practically invisible from directly ahead, as viewed from the sub's deck when the plane was attacking. About that time the subs began to carry radar, which eliminated most of the advantages.
