I had a neighbor growing up that had R/C airplanes,especially gliders,he would put all kinds of colored lights on them and have them go off and on all the time,one night he scared so many people that people were calling the airforce base to see if it was really a UFO,he was detected by a guy on the ground who had one of those really powerful flashlights,Q-beams,I think their called,this always makes me wonder when these people go out to the desert why don't you carry one of these with one in your car/truck,plug it in and shine away.
