Around 9:30 PM: On Staten Island Expressway at approach to Goethals Bridge. My brother and I first noticed the object to our right hovering over Elizabeth, New Jersey. It resembled a large helicopter, accompanying taillight and headlight,except for a large blue screen that seemed to envelop its starboard side. The object appeared weighed down by this screen and while it hovered it also appeared to be stationary in the sky. After crossing bridge and entering New Jersey, object gradually hovered towards the northeast.
