While driving my tanker truck from delivery site..I turned onto Harris Blvd headed west toward I-485 at approx. 0745 or so and noticed an aerial vehicle I first mistook to be a plane. Upon closer examination this caft looked like a cylinder ..siver in color with gray wing like triangular structures pointing straight down with what appeared to be bolts on the winglike structure facing me. Having been in the US Navy I can only appear the winglike structures consistency to that of gray painted iron with bolts on it and a wire that looked attached from one wing at back to the cylinder and maybe one at front. The craft traveled at a pretty good pace and crossed from my left to right just over the treetops, and I watched as long as I could before it dissappeared over the trees. I didnt get overly excited as I have seen a closer encounter back in 1973. I never reported that one. I am not sure if this was extraterrestrial in origin or manmade. What is weird is it had no normal propulsion systems..engines, rotors or horizontal wings or rudder and stabilizers..yet it glided with ease over the treetops. I saw it only for a few seconds but it was fairly close and easy to make out detail. No noise from it though my windows were up. I have seen drones before..and that was another thing I thought it might be..but dont think so due to lack of all the things Ive seen on large and small drones. If this is our tech than its pretty advanced stuff.
