The fireball was headed almost straight down from my perspective for 10-15 minutes, then it almost suddenly changed its trajectory (still downward, but VERY MUCH less so) so that it was headed eastward. To equate it's trajectory to the "hour hand" as represented on a twelve hour analog clock, the first fifteen minutes the fireball appeared to move in a "5:45" direction downward so slowly that it almost seemed as though it was barely moving at all. Then within less than one to two minutes, it was headed toward a "3:30" position (toward my right, very slightly downward, but much more leveled out in a direction horizontal with the horizon), and moving at a much greater speed until it finally disappeared behind the Olympic Mountains range. It was a pretty amazing sight. I took a series of photos on my iPhone (though your website only allowed me to upload one photo). The sudden change in direction was what astounded me the most. I have no experience with meteors or fireballs, but I am ex-military and have experience with aircraft and missile systems. This sighting was remarkably different from anything I've witnessed before.
