I was dropping my wife at work (Boeing Kent Space Center) made left turn to her building. She said to look ahead. At about 20 degrees up we saw 2 very bright whitelights alernating from one side to the other at set intervals every 2-3 seconds. Sat and watched a few minutes. Lights did not move. I told my wife I would drive east out the main gatw then north on Interuban. When I turned north the lights were gone but I saw a faint flat straight sterak going east My wife went outside after daylight there was nothing in that area which would hold lights like these
