Object three lights,two green lights on each side,red slow flashing light just one side, made no soundWas early evening and the sun had set,on my way home south on highway 148 from Mt.Vernon once I had made it about 5 mins from Waltonville on 148 there was an object in the sky that cought my eye. This object had three lights on it with there being two green lights one on each side with an red slow flashing light on just one of the sides. My first thought was an dubble propelled Helicopter. Once about home, I noticed this object wasnt moved much at all. I then got home outta the car and by this time I was running to look at this object as best I could with it being dark and by this time the object had moved over the little town of Waltonville. This object that I had thought was maybe a Helicopter wasnt one because the object made no sound once so ever. As the object moved from being south near Nason to moving West NorthWest over Waltonville, it then moved faster northward toward Mt. Vernon.
