Ball of light over Lincoln County Kentucky

Late one night around 1972 a friend and I were watering cattle that were held in a feed lot.  As we dropped the water we sat on the tank looking up at the sky when we noticed a bright ball of light in the sky just south of us.  This ball of light sat there for about 5 or 10 minutes.  
Then a streak of what looked like fire shot from the north side of the object.  When the fire dissipated  it left another smaller ball of light just north of the larger object. They both sat there for a few more minutes and then the smaller ball of light left to the southwest so fast that it left a small trail of light behind it, this trail lasted only a fraction of a second. 
In just a few minutes the larger ball of light did the exact same thing.  There is no noise.  
I have no idea of what I saw.  I have no idea how large they were because I have no idea of their altitude. 
I do know that in the late 60's and early 70's the Air Force was flying B52's at low altitude over that area.  I may see as many as 4 or 5  a day always flying the same track or course. 
Around 1965 or 1966 there was a military aircraft that crashed in Lincoln County close to a little town called Mckinney,  I understand there were several crewmen that died in that crash. 
There was a lot of activity in that area at the time of my sighting, so I say again I have no idea of what I saw.
Witness indicates that the date of the incident is approximate.  PD
