For reasons not clear to me, you can’t seem to get a clean(?) observation of whatever these objects are.
It’s like looking at a fuzzy image of something.
Something like a compact vehicle through an unfocused camera lens.
My vision tended to blur when I would look up from my instrument panel to where the object was.
This was not just my experience, it was a similar experience to other pilots that encountered these things.
I don’t know, I’m no expert but I do wonder if that is the reason no one has ever taken a clear picture of a ufo?
Whatever these things are, they appear to be quite sneaky.
People who have studied abduction cases, like Dr John Mack (Harvard psychiatrist, now deceased), have concluded that the same characteristic is present in those experience.
There is ample evidence of "something"...but, whatever it is, it is effective at keeping itself hidden behind a curtain of blurriness and deceit.
