3 multicolored craft observer traveling in sky and turned off lights as commercial airplane traveled past in same general areaTight cluster of multi blinking colored lights (white, blue, green, red). Observed through binoculars. clusters appeared to be 1 craft. At first 2 clusters which moved slowly around and next to each other minutes. Occasionally lights would go out completely as in when an obvious airplane closed in on their position but at a different level. Plane was not interacting with craft and kept on its flight pattern apparently unaware or unconcerned of blinking lights. When plane was (I assume) far enough away, the lights on craft came on again and from one of the clusters emerged another seemingly smaller craft with only white light which moved very quickly away from the main cluster. The two clusters (crafts) were getting smaller. Apparently moving away from me closely followed by the smaller white light craft till they were out of rang of my binoculars. This whole incident took about 15 to 20 minutes. I had my wife occasionally take a look at what was going on. No noise. I have observed these same type of craft in different parts of the sky many times. I didn't know there was this place to report it and didn't really think about doing it till today.
