I saw a video clip on how "the military" was researching how to deal with the potential threat of UAV's or drones, and this made me wonder about various SIGINT technologies might--and perhaps already do--interfere with our flying of our radio-controlled quadcopters, etc. Perhaps development and testing of SIGINT technologies might explain some of the uncontrolled situations that some on this forum have mentioned--such as fly-aways and crashes? In the following video clip, the person being interviewed mentioned how unmanned drones can be built by anyone in their garage, for example: http://video.foxnews.com/v/370881111900 ... ed-drones/ SIGINT is nothing new... I wouldn't call it news, but it's something that could be difficult to detect and prove. BTW, SIGINT could mean Signal Intelligence, Signal Intercept, Signal Interference. Call it what you want--even tactical and strategic communications apply as SIGINT is a form of that.
