The craft up close was enormous and turned on a semi -circular white light which wrapped around it's flattenend shape.

I first saw it about 30 degrees from the zenith and to the South West.At first it was a pinpoint of white light moving towards the horizon as it moved(maybe in decent)it changed colors in a spectral sequence of white/blue/green/yellow/orange/red. It now appeared as two red lights near the horizon in the South West.Off to the right, a small plane seemed to be approaching It's  last position,and then to my astonishment a brilliant white light happened near where they would have met.Now I was peering intently;thinking an explosion had occured.But then I saw the two red lights again and now closer and apparently approaching me. It moved slowly and I thought at first I was looking at a large low flying plane however the red lights were steady and not blinking and as it drew closer I noticed it had only a low buzzing sound.However even when it was  just above the roadway in front of my house I still thought it was something from,near by,Stewart Airforce base.But then it turned on a white light which clearly revealed it's shape.The light wrapped around the front of it as a semi circle and I could also see it had small wings which were more like fins and the red lights were at the ends of the fins. It was 200-250 feet across and 250-300 feet front to back it's height was 25-50 feet. It was moving very slowly at 150-200 feet above and maybe 15mph ;the whitelight lit up the roadway.I noticed a slight wobble or hesitency in its forward motion as if it were moving within some kind of field. When It turned off it's main light which may have been on for a minute it began to pivot around one off it's fins and then I was directly beneath it where I could now see a third red light at it's rear and it's full shape from below as a flattened oval and the fins made it seem triangular. It continued over our house and then to the fields behind. I then ran Inside my brother was watching Jonny Carson. We both watched it dissapear banking behind the trees to the North East.
