Driving around after swingshift to relax. Drove by familiar watertower; a red, flashing light caught my eye--to bright for the tower light--looked up and saw a two-tiered vessel--very clear because of low cloud over--big as a house, close, tipped slightly toward me. Did not blink, stopped car in middle of street, got out of car, stared.

I was working at Boeing at the newly opened space center. The red, flashing light first caught my eye, outside line of vision.  It was VERY close--just above the water tower, clearly outlined against the low cloud cover: two tiers, one smaller on top with large, red, clearly defined lights revolving clock-wise; the bottom, larger tier, with same-size green (traffic-light "go") lights, also revolving clockwise, but a little slower than the upper, red lights. As big as a house; no sound. As I watched, without blinking, it slowly moved in my direction, and after 1-2 minutes it disappeared--no sound, just poof--gone. It was about 02:00 at start; 02:10 when I arrived home about a mile away.
