Went to front porch to sit and looked over the horizon. Bright light appeared stationary, then 2 others appear in a row stationary. Planes nearby traveled past them so I know they were stationary. they pulsed red, orange, green and yellow. Once began to travel accross the sky while the others stayed stationary. My eyes followed the traveling light and spotted another group of 3 lights in a row much dimmer. I got my binoculars to see a large object (cigar shapped / maybe disk like) travel across the sky. it travel right in near a radio tower. If i held my arm out in front of me the radio tower was the size of my thumb on its side. this object was the size of 2 of my thumbs on there side. it was the larges object I have ever seen in the sky. made no sound and traveled real slow. I went to school next to Dover AFB in Delaware and am very aware of the large cargo planes. This was no plane.
