http://www.cnn.com/2007/US/01/02/ufo.sighting.ap/index.html Looks like a group of United Airline employees including some pilots reported a UFO over O'Hare Nov 7. FAA isnt investigating. They reported a spinning disc shape object that was hovering over the airport then shot straight up but the FAA is saying its just weather. .Interesting we are just hearing about it 2 months later. The workers included some pilots. I would guess they werent told by the govt that there is no such thing and not to believe their eyes. I would like to see more statements by the witnesses. Interesting. Perhaps it was Swamp gas,or the planet venus,or a flock of birds or the weather or perhaps mass hallucinations,etc etc. (edit) better info can be found herehttp://www.nuforc.org/ Its about halfway down the page. Looks like others saw it including a mechanic taxiing a Boeing 777.
