Myself and 3 friends witnessed a circular shaped craft in the spring of 1967 hovering over a railroad track.

In the spring of 1967 3 friends and myself were returning from Rock Hill, SC, to our homes in Edgemoor, SC.  It was approximately 1:00 AM when we witnessed a circular shaped craft hovering over the Seaboard railroad tracks.  This was to our left, and the craft was approximately 100 feet from us hovering at around 60 feet. The craft was approximately 40 in diameter and had colored lights around the edges.  We pulled over into the driveway of a gas station (closed at the time) and we all got out of the car.  The craft made no noise as it proceeded to pass over us to our right. It then hovered over a local residents front yard, and at this time was approximately 100 + feet from us. A cylinder of light came from the bottom of the craft as if taking samples from the yard.  This light defied the laws of physics, as you could see the bottom of the cylinder(of light) decend 1/2 way, 3/4 way down, etc. before reaching the earth. The light then ascended in the same manner, and then the craft vanished in thin air.  Again, making no noise whatsoever.  We then jumped back in the car and sped to our homes in a state of terror.  I have never officially reported this in 33 years but have told this to many friends and relatives.  Some believe, and of course many laugh, but this really happened to me and my 3 friends.
