the object was standing still in the sky , no noise,as close as tall skyscraper, triangle shaped, whites lights around the edges

I was driving northbound on the Garden State Parkway........I watched it from a distance....it wasn't moving. It was a triangle shape with lights all around the outside edges...white lights.  As I approached the Mullica River Bridge I became frightened....I realized how huge it was as I drove under it.  I don't know how high it was but was lower than any aircraft would travel.  As you know.....this location is very close to the Atlantic City Airport.  
At first I thought it was a group of helicopters...flying in formation....they seemed to be standing still.  I was driving alone with my 3 small children and I didn't really want to stop to look but I did......I pulled off to the shoulder of the road and only rolled the window down and looked up...I was afraid to get out.  At that time I could see that it was one huge triangle shaped object......it was not moving....or moving so slow I couldn't tell...there was absolutely no noise.  It seemed to be pointed in the direction of Philadelphia.  
It was very frightening and no mistaking how big it was....it was a very clear night and easy to see that the object within the lights was solid.  I continued on my way and watched the papers and the news to see if it had been reported.....it wasn't.  I didn't count the lights on it but there were enough to tell from a distance that it was triangle shaped.  The total experience lasted about a half hour....for me.....it was still there when I left.
Witness indicates that date of sighting is approximate.  PD
