Long white object caught during eclipse

On August 21, 2008, during the eclipse, a young woman has snapped a long bright UFO not visible to naked eye over Glenrock, Wyoming. What is it?

Witness report:

Captured this photo in reverse mode while watching the eclipse through my cell phones camera. Upon viewing the photos,noticed something odd above my shoulder. Zooming in on the photo,I thought it worthy of a professional opinion.
