One morning me and my children were leaving one of the schools which is nearby another school we happen to notice these silver disc lights in the sky i took a picture and two videos. you will notice that the light in the middle stays still and one of the lights moves towards it and then under it. i was freezing so the footage is on and off shakey. you can hearvmy children count them. they just went back into the coulds after awhile. i thought at first they were planes but after watching the videos i was convinced they could not be. we have had lots of activity in illinois. our family does not know what these our our some of the other strange sightings and experiences are-but its not natural.
