Cigar-shaped UFO flying over Cantonment, Illinois

On June 15, 2012, an inhabitant of Cantonment (town located in Escambia County, Florida) took photos of a helicopter in the sky. Later by looking these pictures, he noticed a long cigar-shaped UFO. What is it?

Witness report:

Not much to tell here as I did not notice the object until i was looking through the pictures I had taken that day. As you can see the sky was beautifully clear and I was outside when a Blackhawk helicopter came flying over. I started shooting multiple frames with my Nikon D60 as the helicopter flew overhead. I just happened to notice the elongated black cylinder/cigar shaped object in the lower left corner of one of the pictures. Some folks told me that they thought it was a bug, but I have to disagree. As you can see the helicopter rotor blades are captured perfectly and I'm sure they are rotating much faster than if a bug were to be flying through the frame. If it were a bug then I would expect it to be a single point, maybe a little bit of blur but not like what is in the photo. Curiously my maximum resolution picture of this event has vanished from my computer. No idea how this happened. The original picture was shot at 10.2 mega pixel. This pic is much lower resolution but you can still see the object. Just zoom in to the lower left corner and you will see it. So.... any feedback on what this could be? And please don’t cry hoax! I don’t even know how to use Photoshop.

Peace all, eyes to the sky
