Contrails, also known as a vapor trail, is a term used to describe the streak of condensation left behind as a plane flies through the sky. The condensation created from the planes exhaust are actually artificial cirrus clouds. Often in a photo critique comments will be made recommending the removal of this visual pollutant using a variety of photo editing tools.
Example of a contrail removed from a landscape photo:
