It was nov 17 2017, approximately 3pm. i was driving home on the interstate (i57) headed north. i had been capturing a lot of ufo's on camera outside of effingham,illinois where i work .It got to the point that it seemed i could get at least 2 or 3 pics a week by just randomly taking photographs of the sky. they were either triangle,rectangle,or shaped like an bottle of penzoil. on this day i felt i was being watched so i decided to film my rear view mirror on the driver's side. i noticed immediately an object by the sun lower its altitude and then go back up. it reminded me of a large insect/robot. it stayed with me flying up over bridges as i went under them and dodging other vehicles. at one point it had to maneuver around trees on the side of the road. that is when i captured the best footage of it. it had a half a ball of light on the bottom and smaller ones with it. i thought it shot at me and could hear it hit my vehicle. at one point a small one or a projectile nearly hit a school bus. i became angered at one point and said "do you know who i am??" that is when a orb shot towards them. either from me or from somewhere else. i lost track of it as i got into town. the entire event lasted approximately 15 minute. during the event: i felt attacked and invaded. after a few months i feel almost as if it was a test. i feel like that because i have many photos and another video of black objects going into a partial rainbow. i had 3 cameras running that day. 1 was in sepia mode and captured them and an orb come out of a field. the 2 cameras without sepia captured only the rainbow.
