I went outside to let the dogs out around 9:30 - 9:45, I stepped off the front steps and started watching the sky. We live south of Everett Boeing and there are all kinds of planes always flying by. I love to watch the sky, birds during the day and planes and then to see the stars at night. A smaller aircraft flew south with the typical noise and blinking lights, nothing unusual there. As it flew south and I started to lose sight of it I looked back above the house and noticed these shapes above me flying from north to south. 3 cigar shapes, connected by glowing pale white to bluish light, they were at a slight angle to each other, stacked at an angle makes more sense, there was a pulsating light going through each individual one. There was NO NOISE, none. They flew slower then the plane that had gone by, much slower and again no noise, I was able to watch them for 3 - 5 minutes and then lost sight of them.I almost cried it was so unreal to me to be seeing this.
