zig zaging point of light witnessed by dozens in northern West Virginia

I don't remember the exact date or time but this event is varifiable by a local newspaper article (I believe it was the local news paper in weirton, wv ).
 The sky was completely clear.  There was very little ambient light in this area.
 The object was in the southern sky.  It moved covering the area between 40 and 70 degrees vertically from the horizon and a horizontal area of about 30 degrees.  The object did not make any sound that I could here.
 The object moved at a continuous velocity.  When I say a continuous velocity, I don't mean on average.  I mean that it's motion was mechanical in nature.  It's motion made it obvious that it was an engineered device of some sort.  It was very precise in it's movement and speed.
 The object would move in a straight line for a second or two, and then continue at another angle between 90 and 180 degrees of the preceeding path.  It did not stop or even slow down for these changes in direction.  I can't call the changes in direction turns, because the motion was not at all curved.  The changes in direction were precise corners with no change in velocity.  This motion reminded me of the motion of a spot of light on a vector CRT or that produced by vector controlled laser optics.  By the way the object moved, it looked as if it had somehow been projected onto the clear night sky.
 The object itself was a point of blueish-white light not much different from any star in the sky that night.  It was dimmer than the brightest visible star but brighter than any moving satalite I've seen with my eyes alone.
 I saw this while relaxing with my grandmother on her patio.  We would often stay out late, listen to the radio and talk.  I was very dissapointed when the object finally vannished low in the sky.  I was unable to get my grandmother to see the light.  I wanted a witness to my claim but went to bed knowing I was the only one to see the object.
 The next morning my grandmother and grandfather called me into the kitchen.  A small article in the local paper explained that dozens of people in northern West Virginia, including law enforcement, had reported seeing a ufo that zig-zagged across the sky befor disappearing behind the hills.  It seemed I had some witnesses after all.
 A bit about my background-  This was my first UFO sighting.  I was about 14 years old.  My grandmother was in her 50's.  Everyone in my family- I mean everyone has or has had a belief and interest in the spiritual/ paranormal.  My interest in such things is probably the strongest out of any of my family aside from my uncle when he was younger.
 I have had many dreams about future places and events.  Some have already come true in ways that were very obvious to me, others I feel will, in time, unfold.
 I have a background in electronics, fine arts, and music.  I have composed two feature length musical scores for B-budget films.
Date is approximate.  PD
