Well that's damned cool. This post predates my involvement here at AE. I tend to skim through the videos and pics because usually it comes down to : look, up in the sky ... it's a bird, plane, no no ... not him, balloon, bird, plane, cloud and so forth.
No idea what the hell that thing is, but assuming it is a real vehicle from Elsewhere why is it behaving in that fashion? Reminds me of playing with my cats with a laser pointer. You want to really speculate, maybe that is the reason .....
Add it to the pile in the WTF category.
After thinking about my sighting as a kid alongside five of my neighbors as we watched a pair of objects zig-zag across the sky in perfect close formation at supersonic speed, I can only assume that those maneuvers were a deliberate effort to draw our attention. Because otherwise it makes zero sense, and involves serious risk, to move from point A to point B in a zig-zag when a straight line is safer and more efficient.
The erratic motions of that object may have been executed for a similar reason, as to say "look at this folks - I'm not a balloon or other prosaic object." Perhaps it's a challenge: "try to figure out how I'm moving like this without wings or thrusters." Because if we can figure out how to replicate that propulsion mechanism, then we'll have the tech to traverse the stars. And perhaps, like in Star Trek, that's the prerequisite for making contact with a technological civilization like ours: the attainment of warp drive capability.
The radar return signal displayed at the bottom of that video is particularly fascinating: it looks like the object decided at one point to simply go radar invisible - the radar return just flat-lines all of a sudden.
And this video is an excellent example of what we've discussed before: it takes a military-grade cinetheodolite, and ideally an embedded radar signal like we have here, to really properly capture the presence of an exotic object in our skies. No iPhone or ordinary 35mm camera is capable of resolving a 30-50ft object in the sky at aerial distances which usually entail multiple miles of distance. An advanced long-range telescopic video system like this, or those sweet $3M Raytheon targeting pods on the F-18A interceptors, though - they can get the job done. But only the military has that kind of tech routinely deployed and capturing this kind of thing, and until about a year ago they were sharing none of it at all. Hopefully those three brief and blurry clips released over the last 13 months were just the beginning...
