I was on a routine patrol on a state highway in Massachussets, (ironically only a few miles from my home). It was about 3 am in the morning and I was heading north bound when I observed approximately a dozen seperate lights on the initial horizon. There were about six of these "lights" in "opposition" to each other approaching the others at a very rapid pace.

My first impression was that these "lights" could be searchlights operating from two seperate directions but in synchronization to each other. It suddenly occured to me that no power on earth could synchronize these lights at the speed and directional changes they were operating at.  At this point I was so taken aback I actually ran my cruiser off the roadway.
I took the next exit (my home) and parked the cruiser in my yard - we lived on a 90 acre stretch so it was isolated.  About five minutes later I looked up at the sky and saw an enormous, oval shaped object flying approximately 300-400 feet in the air in a westward direction - due to the darkness, the altitude was an approximation.
This object approached my direction.  I stood in the roadway attempting to interpret what I was observing - the craft made no loud noise but rather as it passed overhead I could only describe it as a "whoosing sound" - very quiet.  At certain intervals  there seemed to be a circular, revolving series of low impact lights surrounding the craft which was moving rather slowly to the west.
I went into my home to wake my wife but she was too frightened to step outside.  Rather than reporting the incident I tried to call Otis Air Force Base but the lines were jammed, as were those of a local police department - as discretion is often the better part of valor I put the incident in my own "I don't know file" and just let it be.
Date of incident is unknown to us, at this writing.  We will attempt to obtain the date from the witness, who describes self as a public employee of the State of Massachusetts.  PD
