Flat all black almost like felt material coming toward road I was on. I thought it was a medical helicopter landing for a car accident, then it turned and kinda looked like a hang glider but it was so black i could not make out a good shape. I opened my window to listen for sound and there was none. I pulled car over and began to take video. It moved in many direction and then went straight up until i could not see it. It was the size of a small helicopter, kinda of liked like a giant black batman, but more of a craft. Daylight busy road. Hovered over the Hudson River for about 5 mins.
