Black triangle with yellow lights on either side of it. It hovered for 5 minutes and vanished after I took my eye of it for 1 sec.I was driving and noticed an object hovering in the sky. It was black, triangular, and appeared to have a white or yellow light on either side of it. The lights were static and not flashing. The object did not move except for periodic lateral sways that were not that dramatic. I pulled into a parking lot to stop and get a better look. With my eyes on it the entire time, I parked, and when I emerged from the car, it was just gone. No sign of it at all in any direction. At the time I was viewing the object, there were 2 helicopters near by but flying low that appeared to be approaching the object from opposite directions. After I had emerged from the car and realized the object was gone, I also realized one of the helicopters had vanished as well and the other one had turned back toward Albany. It was strange.
