UFO visits Earth (is it the same one again and again?)

I would just like to say that I don't not believe in UFO's. Having said that, it is getting harder to believe recent reports of a UFO sighting at O'Hare International Airport in Chicago because of one simple fact... no images. How is it possible that in today's world a UFO appears in a public place and no one takes a picture or video of it with their camera phone? I'm not sure I will be able to ever again consider believing that something seen by many people really happened if there isn't an image (preferably multiple images) of the incident. It's a sad day, because I want to believe, I really do.
