Researchers in the US and Britain have unveiled their blueprints for building a cloaking device.
PARIS: The age-old fantasy of rendering objects invisible took a sharp step toward reality Sunday when scientists said they had created a material that can bend visible light in three dimensions.
AS YOU may have heard, this will be the year. The Large Hadron Collider - the most powerful atom-smasher ever built - will be switched on, and particle physics will hit pay-dirt. Yet if a pair of Russian mathematicians are right, any advances in this area could be overshadowed by a truly extraordinary event. According to Irina Aref'eva and Igor Volovich, the LHC might just turn out to be the world's first time machine.
It is a highly speculative claim, that's for sure. But if Aref'eva and Volovich are correct, the LHC's debut at CERN, the European particle physics centre near Geneva in Switzerland, could provide a landmark in history. That's because travelling into the past is only possible - if it is possible at all - as far back as the creation of the first time machine, and that means 2008 could become Year Zero: a must-see for the ...

If the aircraft was invisible it could not have cast a shadow due to the physics of light.
This is what metamaterials theoretically can do: They guide light around an object, rather than reflect or refract the light. So to the light waves -- and the human eye that perceives them -- the object might as well not even be there. If the light waves can be guided by the metamaterials around the object and back to its original course, the object wouldn't cast a shadow, either. This is another goal of using metamaterials to create cloaking devices.

This isnt new - I saw this on Future Weapons a year ago. They showed a man in uniform in full cloak and explained it just like the article on DC

You could not see the guy unless you were looking for him. Like heat shimmering off pavement that is what you saw a shimmering reflection of everything behind or around him. It was kinda creepy.
If the general media is just releasing this I am sure the gov has had it for some time now.

The tech is over a decade old, and was on tv last night as a coincidence. It is a thin film covering that senses what is behind every angle and then displays it. If you look up and its blue the film colors the bottom blue. If it passes a cloud it mimics the cloud very much like the lizards in many places in the world. Although they look invisible you can see heat waves from the engines and hear noise.

I saw a short bit of info on the net that told about new things
in aviation and there is a device to be used on USAF aircraft
that electronically? or by computer allows the airplane to change
the color of the craft to mimic the sky's color so it appears to
be INVISIBLE. If this is a STEALTH airplane.......it's hard to see
on RADAR or by your eyes. Now all we need is alien/Ufo tech-
nology for the noiseless Saucer propulsion unit.

Hi JFJ,
You may not have seen it but I edited the OP to say that I thought it might have used fiber-optic technology which makes it appear to be invisible by mimiking what is beyond it on the side you are looking at.
The plane is still physically there, so it would indeed have cast a shadow.
Very possible then. I know there are several companies experimenting with applying electrical current to metal paints to create memetic responses
Here's a quick example I found

That is exactly the kind of thing that I was thinking about, so thanks for posting the link. If that's what's in the private sector, then imagine what isn't!

Interesting read here thanks.
I have just recently started reading about the supposedly "new" invisibility tech that we have. But as I think we all know, when we are finally told of a new technology, it has actually been around for many years, and they only give us hints of it and make it sound brand new. I would not be suprised at all if there is a way to make an entire airplane invisible. I will do a little research on this subject and see what if anything I can find. Thanks again for the OP.

I read an article, which I will try to find, that discussed some of the possible 2nd gen addons to the F22 Raptor. One of the addons was a skin that had sensors and would change colors depending on the environment it was flying over, under, through, etc..
I believe the source article was from DARPA if that helps.
