HUGE disk hovering over the city of Paterson in the very early 1980's.

I am not sure of the exact date, but it was around 1980-1081. My now husband, then fiance, were sitting in a PARKED/TURNED OFF car at Garrett Mt. New Jersey, which overlooks the city of Paterson. He was sitting in the drivers seat and I was sitting in the passenger seat. We were looking at each other and talking. Suddenly, we noticed a HUGE disk hovering over the city of Paterson! It seemed as huge as the city itself. Underneath the disk there were round lights of red, blue, green and yellow. The lights seemed as though they were rotating. Within several seconds the radio started to flicker on our PARKED/TURNED OFF car. It was a fuzzy, unclear signal. I remember the car sputtering as though the engine was trying to turn over, my husband does not remember that; he only remembers the affect that the craft had on the radio. Then, just as suddenly as it appeared, the disk was simply gone. There were other people parked there that day. The odd thing is that we never got out of the car and nobody got out of their car. We have been searching for someone else who saw this.
Date is approximate.  PD
