My wife who is a huge skeptic witnessed a steady moving orb that was completely silent pass over her head it covered a few miles in less than 30 seconds, had no FAA required blinking lights and was bigger than her thumb held out before her...she freaked a little when it got over her head due to the size and the fact that it seemed it swelled in intensity when it got over her head causing her to hit the record button again on her phone... She continued to watch as it went over the building she was standing next to and lost sight of it. We have both seen the space station go over before... it was way to big and low flying to be a satellite. She estimated the size to be bigger than a truck, It came from behind Franklin mountain and over her head in less than 30 seconds that is over 5 miles from where she took the video...near the Oneonta Waste treatment center. She continually tried to make sense of it and couldn't. It seems a drone would have required it to be controlled from over 5 miles away....lost as to what it is, so it quite literally becomes an unidentified flying object.I have a video of the event
