Disk over Birmingham (NE of), AL

The report, as filed

I snapped this picture from my seat on a flight from San Francisco to Atlanta. The picture was somewhere northwest of Birmingham, Alabama. I noticed it outside my window, and figured it was another airliner. After observing it a few seconds, I noticed it didn't look like another jet. I couldn't see any wings or tail fin. It was in view for maybe 20 seconds or so before it changed directions and went out of my view. I am not sure of the time. The only reason I have a rough idea of a location is because I noticed the guy beside me had his flight tracker up on his seat monitor about 3 minutes after my sighting. I was heading East, the object appeared to be heading southeast at a 45 angle to us but never seemed to get closer or farther from us unti it changed its direction to south. The object looked whitish in color, shaped almost like a blimp or a football. My best guess would be 10-20 miles away from our aircraft.
