UFO Sighting in Herrin, Illinois on July 20th 2015 – Was filming storm clouds with my iPhone and saw the object when reviewing video.

I was outside in my front yard filming storm clouds with my iPhone. I saw nothing unusual at the time, but when I reviewed the video I noticed an object zip out from behind the trees flying from NE to NW. I watched the video over and over and took screen shots at different frames. It's a disc shaped object, but is going so fast that it's only for a brief second that you can see it. You can see it in the video around the 30-32 second mark.
