Ufos using acoustics for levitation?

You can also see the "bulbs or bubbles" on the bottom of most photos. It seems like most UFO photos are always blurry or out of focus, maybe it has to do with the vibrations from pulling in the frequencies?
 
That's a safari hat...... :-D ;-)
 
This to me is still the closest resemblance on how people describe them flying and making sharp maneuvers etc.
