It's only a UFO (the key word being unidentified - not little green men)because it's such a crappy picture we can't tell what the hell it is. I suggest if it's not a watermark on the lens it's a kite, or a R/C toy.
Better yet, I suggest the picture is a 3rd generation as you can clearly see the vertical scan lines, an artifact of a digital scanner. That means the
photo 1st gen was processed on a computer where the object could of been added then it was printed 2nd gen and then scanned (a picture of a picture)
and posted 3rd gen.
Why would anyone degrade a picture in that manner? Clearly faked in order to sell the rag. I have better cloud pics that look like UFOs, but they're
really clouds - move along.
