Long Description of Sighting Report
I was looking at centipede-looking chemytails, no craft observed. Cloud was in the middle of a cloudless sky at the time. Upon looking at the digital photo, the craft is revealed. That is the first three pictures. The last picture taken 12/17/13 at 12:30PST showing an orb like craft emitting cloud or chemtrail upward, and then spreading out in a V shpe as it hits prevailing winds.
