i could not identify this object with any known craft although i has study janes and nasa craft for years!

at 6:50 pm i was leaving home to drive to work when i noticed something falling from the sky. i thought it was an air craft at first, and thougtht it would crash near the shering plough pharmacutical plant i turned the corner to head towards that area wwhen i notice the object stop in midair and slowly hover over the intersection of morris av and north av near the kean college entrance. i then pulled into the seven eleven store to see if there were any people outside seeing this ufo as well. the only one there was the soda delivery man. he was doing paper work in the cab of his truck so i asked him to observe this slowly hovering craft and tell me what it is. he was startled.
it was saucer shaped and had a visible dome shaped top but the bottom was a very dark gray color and it seemed to have some type of movement resembling rippling water. it hovered slowly across the sky towards the sw and dissapeared. the total time that i viewed the object was 3 to 4 mins.
Date is approximate.  PD
