Bright light with shooting star sped to a dead stop hovering strobe.

I saw a bright light flashing, moving from south to north in the eastern sky. Approximately 45-55 degrees above the Horizon. Then suddenly it shot like a shooting star 10 to 20 degrees (at least from my perspective angle) to a sudden dead stop seemingly almost above me. It seems as if it was just a few blocks away or over down town, but seemed like it was only 500 feet above the city! It then began to flash a single bright flashing light every second to two second intervals very steady pace. Not making a single sound! Where it just hung out stationery for approximately ten minutes or so, silently. I called my neighbor out to watch it and witness it too. Which she did.
Behind and above the brilliant flash I could see what seemed like a large bay window. Like maybe an observational window. It was an aqua color.Then it after what seemed like about ten minutes or so, it slowly went out of view behind the building as it moved in a N.E. direction. At first I went back to my porch then decided to walk all the way over to where I had last seen it going behind the buildings. I briefly saw it again but as it kept moving I lost sight of it. So I went back up to my porch. Next thing I knew it was in the deep southern sky traveling west and went out of sight behind the trees.
What it seemed like it did was make a maneuver that was impossible for a human occupant to survive (thus showing off ‘’we are not human”) Then stopped directly in the middle of air traffic flight path from the Eugene Airport and hovered there for ten minutes or so, as if to say “so what are you going to do about it”? I am trained in deep sky observations, and using indirect field of view it see details as I have had a number of large telescopes and have sat on the board of directors of the Eugene Astronomical Society. I can’t say for sure what it was I saw. But I can tell you what it wasn’t. I am not ignorant to the night sky.
