Description: I was driving in South Seattle near the Boeing airport on I-5. It was around 6:00 PM? It looked like a constellation of amber orbs, but nowhere close to being high enough to be stars ( a low Aircraft height). I drifted into a different lane because I was staring at it. Once I got back into my lane I looked again and there were only three left in the formation of a triangle. I was close enough to see that it had no solid structure. It was just lights. During the entire time the lights stayed in one place until I had almost past it and one of the three left it's triangle formation and headed west.
Response of Witness to Questions: I thought about that the lights could be Chinese Lanterns too, but what I saw was so perfectly geometric it was startling. And when the one broke from its formation horizontally that thought went out the window. I looked at some of the pictures from other reports and it's EXACTLY what I saw. This is exciting stuff. Thanks for telling my story.
