Long cylinder flying high in the sky no noice or lights.

Me and my son walked out of the house and Iooked up in the clear night sky to our amazement witnessed a UFO. We have power lines in front of our home, at first I thought it might be a glare from those power lines, not so. We walked to
the middle of the steet past line power lines and veiwed a long silver,gray cylinder object flying high in the sky with no noice or lights. This object had to be at least five football fields long moving slow and then just slowly faded away like it never was there. The stange thing is it seem like the planes switched there fly pattern away from this object on there way to O'hare airport. We took a picture of it, you see the power lines to the left and the object to the right we forgot the flash was on the phone.
