More "Anonymous" Chicago UFO images
Got these in today from an "anonymous source" that at least traces back to the Chicago area. The story behind these is a woman shot them back in August, 2006 out by the La Salle Nuclear Power Plant!
She was concerned and reported them to Homeland Security who told her "someone is playing a prank on you" and blew her off. She asked her son to delete the images from her phone because she wants to forget about them.
Her son (who saved them to his computer before deleting them from her phone) heard about the O'Hare incident and that ATS was looking for images on Coast to Coast with George Noory www.coasttocoastam.com and sent them in.
Jeff Ritzmann has had a very "precursory" review of them and said they are not "Obvious Hoaxes" so I am putting them "OUT THERE" for all to see.
We would LOVE to get more images of "this thing over Chicago". What the HECK is going on in Chicago?
I look at this as simply more data, the more the merrier, until Jeff Ritzmann and David Biedny have had a chance to tear these down to the pixel I am standing by on these, but wow they are impressive in appearence.
