Great post thanks for sharing. I like the follow up u did to call about this. I agree def not a helicopter. If this isn't an actual alien craft of some sort, than worst case its def a reversed engineered craft or drone by the govt. Drone most likely I would say. The lack of sound shows a top secret propulsion system (why I saw reversed engineered)Still exciting b/c reversed engineered tech obviously means we have alien life vising us.
