http://cosmiclog.msnbc.msn.com/archive/2006/05/30/59.aspxLast week's report on the quest for invisibility sparked some pretty intriguing comments, including numerous claims that the military has already developed real-life invisibility cloaks. It sounds a little too much like "The X-Files" to me — but hey,en-USCommunityServer 2.0 (Build: 60608.1)http://cosmiclog.msnbc.msn.com/archive/2006/05/30/59.aspx#66Fri, 02 Jun 2006 16:27:09 GMT8a5d2dbc-a0e4-4c7a-979f-3188051f228e:66Garry Rondeau, Winnipeg, Manitoba, CanadaIn all probability,this technology is already well developed and is most likely being field-tested as we speak! Don't forget, 10-15 years ago nobody would have believed in a Stealth Fighter or Stealth Bomber either!http://cosmiclog.msnbc.msn.com/archive/2006/05/30/59.aspx#108Mon, 05 Jun 2006 17:49:15 GMT8a5d2dbc-a0e4-4c7a-979f-3188051f228e:108James Wetzel, Gilbert, ArizonaInvisibility is not new..anyone ever hear of the PHILADELPHIA EXPERIMENT?!http://cosmiclog.msnbc.msn.com/archive/2006/05/30/59.aspx#298197Tue, 31 Jul 2007 06:18:12 GMT8a5d2dbc-a0e4-4c7a-979f-3188051f228e:298197NLP FanaticI read that this Philadelphia experiment was an elaborate hoax. Quite like the fellows who persuaded the world that the Loch Ness picture was real. <br> <br>71 years after that photograph, the architect of that deception admitted to the dastardly deedhttp://cosmiclog.msnbc.msn.com/archive/2006/05/30/59.aspx#1347735Thu, 04 Sep 2008 19:18:51 GMT8a5d2dbc-a0e4-4c7a-979f-3188051f228e:1347735MattThe Philadelphia experiment was not a hoax, it was an actual experiment. The hope was to make it invisible to sonar. However, all the sensationalist propaganda about it is false, inventions more akin to the Roswell incident than to a hoax. I'm more curious about this Australian engineering outfit that has supposedly defeated radar-absorbing materials and redirecting shapes. Time to research that.http://cosmiclog.msnbc.msn.com/archive/2006/05/30/59.aspx#1545812Wed, 15 Oct 2008 13:16:04 GMT8a5d2dbc-a0e4-4c7a-979f-3188051f228e:1545812Marv, Whiteriver Arizonathe concept of invisibility was tried after the movie &quot;Predator&quot;, it was a projection of the background creating an illusion of invisibility which was featured in military technologies, and I believe newsweek. Einstein worked on this theory and several others during his early years, but all theory.
