A vehicle of some sort appeared to be over the Snohomish/Arlington area that pulsed between a red and white light. There were also one or two other aircraft in the event.

While driving North on highway 9 in Snohomish we spotted a light in the night sky somwhere I believe to be over Arlington or the Sound (hard to tell at night). The light pulsed between red and white in a cycle of about twice every second (two red and two white every second). The light also appeared to be centralized, as in it was deffinately not on a wing-tip, or fin. This was also the only light on the object. There was also at leaste one other vehicle in the vicinity, and possibly two. The primary object maintained a rather steady corse, changing direction about once every minute. The secondary vehicle(s) appeared to be following or chasing the primary object, but not maintaining as steady of a corse. The other vehicles had no lights on them except for what appeared to be an engine flame (white). I belive that the aircraft in pursuite were military because one of the engines appeared to fire an afterburner twice during the time that we could maintain visual contact with the objects. All objects appeared to be Northbound and about 10,000 to 20,000 feet up, although this is just a guess.
