Walking into my home. Standing in the back yard. Thousands of lights flew over from the SE heading NW at an extremely fast rate of speed. I thought it was a plane, but the mass quickly expanded beyond that of anything we know. These things flew at an unworldy speed. There were commercial flights in the air at the same time. They stood still in comparison. The lights rolled over like a wave, silently at a very high altitude. The formation spanned over a mile. It was huge. There were thousands, all together. No trails, nothing. Lasted about 15 seconds. Amazing and unexplainable. I am going to look for them again, and I am going to capture footage. I felt amazed to see this. I've never seen anything like it in several decades of stargazing. Convinced.
