UFO sightings report: Im a photography student and i was taking pictures of a double rainbow and the pink red sky when i capture something im not sure what it could be..

First i thought it could have been a stealth fighter bomber but I heard nothing on the news.. is it possible that it was just a bird that i missed while shooting? I didnt really see any at the time.. I did take a photo prior to this one of an airplane and it looks nothing like that on this photo.
