Boomerage shaped object flying low and quiet.My 19-yr old daughter and I were headed west on 264 through Ganado when I looked up and noticed an object flying at street-light level passing across/above the roadway in a southwest to northeast direction that we were on. The large object had a boomerang shape with one light on one end, a light on the other end, and one light in the middle. My daughter and I both were surprised by what we were seeing and told her to roll her window down and look out the window. She heard a humming sound. Nothing like a helicopter or plane sound. It moved above us real slow and low. We continued to watch it until it was out of sight. We both got chills up our back and didn't know what it was. We kept trying to look for it while we continued to make our way home but never saw the lights or the object again.
