Massive fleet of amber green spheres flying in odd formation over Wichita, Kansas

Well i do not remember the exact year but it was about 1985-1987 in the summer.  Me my brother and two cousins were outside in my aunts broken car.  We were just sitting and talking for about a hour.  We all decided to go inside when my brother who is actually five years older than me pointed to the sky and said "Ya'll look, UFO's!!".  
It was a semi-cloudy night but what we saw traveling into the clouds (sort of speak) was what looked like a fleet of spherical UFO's.  This fleet of space craft flew in complete unison in some very odd pattern (kind of like the formation of Canadian geese, but having 90 degree formations of all sorts).  We thought that we were being invaded by aliens as they flew across the sky at a slow motion with out a sound. 
The spherical objects had a amber glow at the bottom. We watched what seemed to be over a 150 craft fly across the sky for about 20 minutes.  
I was young then but i know that there had to be many people of Wichita, , that saw this sight, without a doubt.
Witness indicates that the date of the sighting is approximate.  PD
