http://www.defensetech.org/archives/002286.html This comes from the concept discussed - using plasmas on the skin of aircraft to reduce drag and to reduce the RADAR signature - which is an idea known to serious UFO researchers for some years now. I think it is likely that this technology has been developed or at least tested at some level, and this is seen from time to time. However, the idea that this might be used to distort the appearance of an object is new to me. That is a fascinating idea... I wonder if it is possible [and practical] to do this.
