8 lights in two rows, separate two groups of 4, rotate form diamonds and head off across sky.

I have wanted to share this for many years but didn't know where to do it.
My friend and I and his mother were out on his patio on a nice summer evening in the summer of 1986.  He was leaving for the Navy in couple weeks and we were just talking about old times.  My friends home was adjacent to a 10 acre pasture and on the opposite side of the pasture was a shopping center with the typical bright parking lot lights.  Straight line distance the parking lot was about 1000ft to the north from where were were.  
As we were talking my friends mom said "What the heck is that?"  My friend and I which had our backs to the parking lot turned around.  Directly above the parking lot in the sky where there is no stars because of city lights were 8 lights that were rising up.  As I looked at them the kind of shimmied side to side as they went up and I initially thought that someone had let go of a bunch of balloons and we were seeing the parking lot lights reflect off of the bottoms of the balloons as they rose.  This was quickly not the case as the 8 ! lights (in two rows of 4 with each light in the opposite row halfway between the next.  The lights continued up in the sky and were now passing through the sky with stars and these lights were now as bright or brighter than the surrounding stars.  They proceeded up to about 45 degrees then stopped.  The 8 lights now separated horizontally into to rhombus shaped objects.  They then rotated about 45 degrees counterclockwise to form diamonds.  The lower diamond proceeded to move up side by side with the other diamond and then connect.  The two diamonds then started moving across the sky north to south.  They were going about twice as fast as an orbiting satellite for reference.  I followed it accross the sky until a large pine tree blocked my view.  As I ran around the other side of the tree the object was gone.
