Extremely bright lights (2) fluctuating downward, and 5 + times brighter than an plane (AND SILENT). Low Level Flight pattern.I first notices a VERY bright light coming out of the South and proceeding more or less due North. Its lights were "intense" to say the very least. I have been around aircraft for many years in the USAF so I know what landing lights look like and the intensity of even the largest airplane. This had to be 5 times as bright (or brighter). Additionally, the lights were 2 seemingly separate but ? attached ? lights shining straight down.The leading light was the largest and the trailing attached light was 50% (plus) as bright. It seemed to be having trouble turning its lights of as they were fluctuating together but randomly. I perceived that fact only because I could think of no other reason for such random fluctuations.As it came overhead I noted that it was so low that it was in the region where local single engine aircraft would fly and NOT where Passenger/Military aircraft fly in our area.As it passed overhead I heard absolutely NOTHING, not anything. Total and complete silence.It lit up my yard and everything within a mile or more so that I could clearly see my dog who was in the back yard with me. It was casting so much light that I could distinctly see the shadows of my fence, my dog, and the house. Not distinctly but notably casting a perceivable shadow.The light itself was PURE white and there were no flashing lights (running light) with which I am extremely aware of due to being around airplanes of all kinds (including stealth).It continues STRAIGHT north and eventually either disappeared over the mountains to the north of us or was able to extinguish its lights.To indicate my professional credentials. I worked on the NASA Space Station Design Team (Technical Staff - Computers and such. I have been to most NASA sites stateside but not all. I also worked for U of Colo CASA/NASA research team and built the guidance system and wiring harnesses for 2 research rockets which were trying to locate the center of the universe.One rocket was fired from White Sands Proving Ground and the second was fired from Woomera Australia (NASA). It failed to release one stabilization chain and the rocket tilted and was quickly over ridden by staff to re-fire the explosive to release the chain. It flew toward Adelaide and crashed just on the outskirts. It never got into space to finish its mission.NASA took over from there and I have never heard back from anyone but understand that they did determine that the NASA mission did confirm the land coordinate as well as the White Sands data. The center of the universe is just beneath the "Eye of Horus". (Where the Gods watch man, from according to the Egyptians.I spend 1 -3 hours star gazing at night on more than 9 out of 10 nights and can spot all kinds of satellites and aircraft and can distinguish the difference easily.THIS ONE I CANNOT EXPLAIN.((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information.
