I was outside looking at the chemtrails when I saw a small blackish in color object moving rapidly along the length of the chemtrail. I can see planes as they approach and depart from either SFO or Oakland airports and this object was much smaller and seemed to travel at far greater speeds than any planes. It traveled half the distance of my vision from the horizon on my right towards center. ( Eastern direction). When a plane appeared and was crossing its path the small object seemed to flicker and dissappear. This is my 5th sighting like this and I have 3 videos that contain these objects. Unfortunately todays I was unable to video. I also have a dozen photos with these objects in them. Usually along a chemtrail. I called my wife to see the object but she couldnt spot it before it dissappeared. I will attach 1 video of 3. At 00:33 seconds this object appears above storage tank on hill and between chemtrail before camera moves away it flashes light as it passes chemtrail and seems to have a means of propulsion that lights the aft end. I did not edit sound or video in any manner.
