But this is the nature of UFO! They're always zipping about in the gray area of "barely detectable". If an object is easy to detect, it's also easy to identify with our array of sensors. If it's not detectable we don't know there's an UFO. So we'll always puzzle over grainy footage and blips on the radar.

These cameras are going to clear up some of the mysteries we've seen in the past. But they are going to find more, further out.
