I'd love to see some calculations on how much energy this UFO would have needed to perform the maneuvers it did. Whether there were any observable atmospheric effects like a wake even though there was no exhaust seen. Did it exhibit observable inertia, in other words did it move like bad movie special effects, or did it move like something real?
In the comments in the NYMag original article, one person wonders if it was the result of some advanced spoofing/decoy technology. I'm not sure what could cause what the sensors observed, but the idea seems interesting and brings a cause "down to Earth" so to speak.
