I know you're perpetually bored and just out to bait 'ufo nuts', as James R loves to troll it, but anyway....I find it curious that given I spend so much time looking at the night sky and often all night photographing nebula and galaxies on a regular basis but never have the luck to see a UFO on any of the thousands upon thousands of photos that I have taken and indeed none of the guys on the astronomy forum I attend have had no better luck. I have been on that forum since 2005 and not one report of a UFO from any of the 15,000 off folk who have come and gone... between all of us there would be millions of photos...I take up to 250 in one evening never a UFO..yet someone going out to get a pizza looks up and spots one right away pulls out their phone and records their UFO ...mmm sure ..those photos are fake for sure..and eye witnesses..mmm...I don't believe them..liars or fools take your pick.
I guess astronomers and astro photographers are just unlucky.
